Abstract
BACKGROUND Sexually transmitted infections (STIs) are a major public health concern worldwide. Untreated STIs may have serious sequelae, particularly in pregnant women. The objective of this study was to assess the feasibility and acceptability of screening and treating common STIs in women during pregnancy in Bangladesh. METHODS Women were enrolled from four maternity clinics/hospitals serving the lower-middle class population in Dhaka, Bangladesh. The participants were interviewed, and vaginal swab samples were collected by clinical staff. Specimens were tested for Neisseria gonorrhoeae, Chlamydia trachomatis, Trichomonas vaginalis and high-risk Human Papilloma Viruses (HPVs) using GeneXpert (Cepheid, Sunnyvale, California). Women were informed of their test results and were provided treatment for curable infections. A test of cure was performed. RESULTS Out of 1157 pregnant women approached, 1000 (86.4%) participated. Ninety-one percent women learned of their test results on the same day of testing. Out of the 996 valid results, 7 (0.7%) tested positive for Chlamydia trachomatis and 1 (0.1%) for Trichomonas vaginalis. There were no gonorrhoea cases. Out of the 971 women with valid results for high-risk HPVs, 46 (4.7%) tested positive. CONCLUSIONS Screening women for STIs during antenatal care was highly feasible and well-accepted in Bangladesh. While the prevalence of common curable STIs was very low, hrHPV infection prevalence was moderately high. Our findings support period monitoring of STIs and continued prevention efforts for cervical cancer in Bangladesh.

Abstract
Background Vaginal discharge is a common complaint among women attending the sexually transmissible infections (STIs) clinic and is a cause for concern and mental distress. It can be attributed to physiological or pathological causes. This study aims to understand the prevalence of various etiologies of vaginal discharge, which would help frame health policies based on local needs. Objectives (1) To estimate the prevalence of discharge per vaginum among sexually active women attending the STI clinic at a tertiary care center during a 1-year period, (2) To identify the organisms causing vaginal discharge, (3) To have a clinicoetiological correlation of the cases, and (4) To identify the subspecies of Candida causing vaginal candidiasis. Materials and Methods A total of 126 patients with vaginal discharge attending the STI clinic at a tertiary care center were included in the study. A detailed clinical history, physical examination of the external genitalia, and vaginal examination were done on each patient. Five swabs were taken from the posterior fornix and lateral vaginal wall for evaluation of the organisms. Results The mean age of the study population was 31.51 ± 7.9 years. Vulvovaginal candidiasis (VVC) was found to be the most common cause of vaginal discharge, followed by bacterial vaginosis, mucopurulent cervicitis, herpes genitalis, and trichomoniasis. The most common species of Candida was found to be Candida albicans. Conclusion Even though VVC still remains the major cause, other viral infections like herpes significantly contribute. Vaginal discharge is an important indicator of women's reproductive health and its detailed evaluation helps identify the prevalence of various STIs in the community.

Abstract
Sexually transmitted infections (STI) symptoms (e.g., abnormal genital discharge and genital sores/ulcers) are a major public health concern in Bangladesh because the symptoms can indicate an STI and cause sexual and reproductive health complications in women of reproductive age. To our knowledge, no study examined the prevalence and risk factors of STI symptoms using a nationally representative sample. This study investigates the prevalence of STI symptoms among ever-married women in Bangladesh and the associations of STI symptoms with various demographic, socioeconomic, and behavioral risk factors using the most recent available data (2007, 2011, and 2014) of the Bangladesh Demographic and Health Surveys (BDHS). The BDHS employs a two-stage stratified sampling technique. The analytic sample comprised 41,777 women of reproductive age (15-49 years). Outcome variables included STI symptoms: abnormal genital discharge and genital sores/ulcers. Multivariate logistic regression was employed to find the adjusted odds ratio with a 95% confidence interval to assess the associations of outcome measures with explanatory variables. The study found that the prevalence of abnormal genital discharge and genital sores/ulcers among ever-married women aged 15-49 years was 10% and 6%, respectively. Multivariable analysis revealed that for women aged 25-34 years, those who used contraceptives and married earlier had an increased likelihood of STI symptoms. Furthermore, women from the wealthiest wealth quintile and couple's joint decision-making were less likely to have STI symptoms. Findings have implications for interventions efforts aiming to improve women's sexual and reproductive health in Bangladesh.

Abstract
Hepatitis C virus (HCV) is one of the leading causes of chronic liver disease, cirrhosis, and hepatocellular carcinoma, resulting in major global public health concerns. The HCV infection is unevenly distributed worldwide, with variations in prevalence across and within countries. The studies on molecular epidemiology conducted in several countries provide an essential supplement for a comprehensive knowledge of HCV epidemiology, genotypes, and subtypes, along with providing information on the impact of current and earlier migratory flows. HCV is phylogenetically classified into 8 major genotypes and 57 subtypes. HCV genotype and subtype distribution differ according to geographic origin and transmission risk category. Unless people with HCV infection are detected and treated appropriately, the number of deaths due to the disease will continue to increase. In 2015, 1.75 million new viral infections were mostly due to unsafe healthcare procedures and drug use injections. In the same year, access to direct-acting antivirals was challenging and varied in developing and developed countries, affecting HCV cure rates based on their availability. The World Health Assembly, in 2016, approved a global strategy to achieve the elimination of the HCV public health threat by 2030 (by reducing new infections by 90% and deaths by 65%). Globally, countries are implementing policies and measures to eliminate HCV risk based on their distribution of genotypes and prevalence.

High-resolution mapping of reproductive tract infections among women of childbearing age in Bangladesh: a spatial-temporal analysis of the demographic and health survey. BMC Public Health 2021; 21:342.

Abstract
BACKGROUND Reproductive tract infections (RTIs) have become major but silent public health problems devastating women's lives in Bangladesh. Accurately and precisely identifying high-risk areas of RTIs through high-resolution risk maps is meaningful for resource-limited settings. METHODS We obtained data reported with RTI symptoms by women of childbearing age in the years 2007, 2011 and 2014 from Bangladesh Demographic and Health Survey. High-spatial Environmental, socio-economic and demographic layers were downloaded from different open-access data sources. We applied Bayesian spatial-temporal models to identify important influencing factors and to estimate the infection risk at 5 km spatial resolution across survey years in Bangladesh. RESULTS We estimated that in Bangladesh, there were approximate 11.1% (95% Bayesian credible interval, BCI: 10.5-11.7%), 13.9% (95% BCI: 13.3-14.5%) and 13.4% (95% BCI: 12.8-14.0%) of women of childbearing age reported with RTI symptoms in 2007, 2011 and 2014, respectively. The risk of most areas shows an obvious increase from 2007 to 2011, then became stable between 2011 and 2014. High risk areas were identified in the southern coastal areas, the western Rajshahi Division, the middle of Khulna Division, and the southwestern Chittagong Division in 2014. The prevalence of Rajshahi and Nawabganj District were increasing during all the survey years. CONCLUSION The high-resolution risk maps of RTIs we produced can guide the control strategies targeted to priority areas cost-effectively. More than one eighth of women of childbearing age reported symptoms suggesting RTIs and the risk of RTIs varies in different geographical area, urging the government to pay more attention to the worrying situation of female RTIs in the country.

Abstract
Introduction: Considering a growing number of female sex workers (FSWs) in Bangladesh, there remains a greater need to reduce sexually transmitted infection (STI) rates, as lower social and cultural status cause FSWs to have less access to education, employment opportunities, and health care, including opportunities for HIV tests, counseling, and medical care. Methods: A cross-sectional study was conducted among 546 street, hotel, and residence-based FSWs. This current study aimed to identify the prevalence and to ascertain the associated risk factors among the FSW populations in Dhaka. Results: We found a majority of the participants were in the working age of more than 26 years for the FSW profession, with a mean age of 28 years. While the majority were unemployed (42.5%), alcohol abuse (p = 0.01) and drug dependency (p = 0.01) had an association, and inconsistency of condom use had a higher risk factor (AOR = 3.54) for a new STI case. Conclusions: FSW-oriented service platform should be integrated with health literacy interventions in urban and rural locations in Bangladesh. Understanding the differences in risk patterns and tailoring intervention will increase contraception use and lower STI cases and improve overall FSW quality of life.

Abstract
Background Herpes simplex virus type 1 (HSV-1) epidemiology in Asia was characterized by assessing seroprevalence levels and extent to which HSV-1 is isolated from clinically diagnosed genital ulcer disease (GUD) and genital herpes. Methods HSV-1 reports in Asia were systematically reviewed and synthesized, following PRISMA guidelines. Random-effects meta-analyses estimated pooled mean seroprevalence and proportion of HSV-1 detection in GUD and genital herpes. Random-effects meta-regressions identified predictors of seroprevalence and sources of between-study heterogeneity. Results Forty-nine relevant publications were identified. Fifty-four overall seroprevalence measures (182 stratified measures), and 8 and 24 proportions of HSV-1 detection in GUD and in genital herpes, respectively, were extracted. The pooled mean seroprevalence was 50.0% (n = 26; 95% confidence interval [CI], 41.3%–58.7%) for children and 76.5% (n = 151; 73.3%–79.6%) for adults. By age group, the pooled mean was lowest at 55.5% (n = 37; 95% CI, 47.5%–63.4%) in individuals aged <20 years, followed by 67.9% (n = 48; 62.4%–73.3%) in those aged 20–39 and 87.5% (n = 44; 83.4%–91.1%) in those aged ≥40 years. In meta-regression, age was the major predictor of seroprevalence. The mean proportion of HSV-1 detection was 5.6% (n = 8; 95% CI, 0.8%–13.6%) in GUD and 18.8% (n = 24; 12.0%–26.7%) in genital herpes. Conclusions HSV-1 epidemiology is transitioning in Asia. HSV-1 is probably playing a significant role as a sexually transmitted infection, explaining one-fifth of genital herpes cases. There is a need for expanded seroprevalence monitoring and GUD/genital herpes etiological surveillance.

Abstract
BACKGROUND One-third of preterm births are attributed to pregnancy infections. We implemented a community-based intervention to screen and treat maternal genitourinary tract infections, with the aim of reducing the incidence of preterm birth. METHODS We did an unblinded cluster-randomised controlled trial in two subdistricts of Sylhet, Bangladesh. Clusters were defined as the contiguous area served by a single community health worker, and each cluster comprised several contiguous villages, contained roughly 4000 people, and had about 120 births per year. Eligible participants within clusters were all ever-married women and girls of reproductive age (ie, aged 15-49 years) who became pregnant during the study period. Clusters were randomly assigned (1:1) to the intervention or control groups via a restricted randomisation procedure. In both groups, community health workers made home visits to identify pregnant women and girls and provide antenatal and postnatal care. Between 13 and 19 weeks' gestation, participants in the intervention group received home-based screening for abnormal vaginal flora and urinary tract infections. A random 10% of the control group also received the intervention to examine the similarity of infection prevalence between groups. If present, abnormal vaginal flora (ie, Nugent score ≥4 was treated with oral clindamycin (300 mg twice daily for 5 days) and urinary tract infections with cefixime (400 mg once daily for 3 days) or oral nitrofurantoin (100 mg twice daily for 7 days). Both infections were retreated if persistent. The primary outcome was the incidence of preterm livebirths before 37 weeks' gestation among all livebirths. This trial is registered with ClinicalTrials.gov, number NCT01572532. The trial is closed to new participants, with follow-up completed. FINDINGS Between Jan 2, 2012, and July 28, 2015, 9712 pregnancies were enrolled (4840 in the intervention group, 4391 in the control group, and 481 in the control subsample). 3818 livebirths in the intervention group and 3557 livebirths in the control group were included in the primary analysis. In the intervention group, the prevalence of abnormal vaginal flora was 16·3% (95% CI 15·1-17·6) and that of urinary tract infection was 8·6% (7·7-9·5). The effective coverage of successful treatment in the intervention group was 58% in participants with abnormal vaginal flora (ie, abnormal vaginal flora resolved in 361 [58%] of the 622 participants who initially tested positive), and 71% in those with urinary tract infections (ie, resolution in 224 [71%] of the 317 participants who initially tested positive). Overall, the incidence of preterm livebirths before 37 weeks' gestation did not differ significantly between the intervention and control groups (21·8% vs 20·6%; relative risk 1·07 [95% CI 0·91-1·24]). INTERPRETATION A population-based antenatal screening and treatment programme for genitourinary tract infections did not reduce the incidence of preterm birth in Bangladesh.

Abstract
Despite a considerable body of published research on hepatitis B in Bangladesh, researchers continue to lament the lack of reliable information about hepatitis B virus (HBV) infection epidemiology. The present review aims to provide a comprehensive survey of the literature with particular focus on a number of epidemiological questions, as well as a commentary on the trends of hepatitis B research as it has taken place in Bangladesh. The key themes to emerge from this review are: first, beyond noting a declining trend, it is difficult to provide conclusive estimates about HBV prevalence in the general population of Bangladesh. The majority of the studies, even the ones conducted on apparently healthy populations, fail to be adequately representative for the reasons explored in the article. Secondly, HBV infection in Bangladesh is sharply stratified across sociodemographic lines, which speaks to the role of awareness and risk exposure in HBV prevalence. Third, more research on occult infection rates is required to estimate the extent of risk posed by the current blood donation screening program, which relies exclusively on hepatitis B surface antigen as a biomarker. The same considerations apply for the comparative importance of vertical versus horizontal transmission and prevalence among particular risk groups like healthcare workers with high occupational exposure. Finally, while recent studies do allow us, albeit with some ambiguity, to draw conclusions about distribution of HBV genotypes in Bangladesh, there needs to be an added emphasis on molecular epidemiology. It is hoped that the present review, the first of its kind in Bangladesh, will serve as an up-to-date summary of the course HBV epidemiology research in Bangladesh has taken thus far, as well as crucial gaps to address going forward.

Abstract
Sexually-transmitted infections (STIs) are highly prevalent in developing countries, including many parts of South-East Asia. The burden of diseuse due to these infections and their complications is enormous, particularly among women. STIs thus present a major public health problem in their own right. Accessible, affordable and effective treatment services need to be made available everywhere. The syndromic approach to STI diagnosis and case management based upon locally adapted standard treatment algorithm is byfarsuperiorto the presumptive clinical diagnostic approach that is still used in many parts of the region. This approach is particularly suitable in areas where efficient and affordable laboratory services are not available. STIs are known to enhance HIV transmission. Effective control of curable STIs has been shown to significantly reduce HIV incidence in popula tions. Such control measures should address all major steps of the Piot model: they should include primary prevention, screening to detect asymptomatic or neglected STI particularly among high- risk behaviour groups, and effertive treatment services for those who seek care forsymptomatic STI. So far the public health response to STI in South and South-East Asia has been varied. Some countries have addressed the problem quite vigorously, but most need to mount a much stronger coordinated response in the face of the accelerating HIV epidemic in the region. There is also a substantial need to systematically monitor and evaluate ongoing activities, including the quality of STI case management, and to make an attempt towards bridging the wide rift between policy and actual practices.

Abstract
Tragically, genital tract infections are still a major public health problem in many regions. This study was undertaken to determine the prevalence of cervical infection with Herpes simplex virus (HSV), Chlamydia trachomatis (CT), and Neisseria gonorrhoeae (NG) among married women referring to Iranian Hospital, Dubai, UAE. In a retrospective cross-sectional survey, 201 female patients aged 16–80 years who referred to the Obstetrics and Gynecology Department of Iranian Hospital, Dubai, UAE, in 2010 were enrolled. The patients were categorized into three age groups: 15–30 (group I), 31–40 (group II), and ≥41 years old (group III). A cervical swab sample was collected from each woman and the prevalence of cervical infection with HSV, CT, and NG was determined by PCR method. HSV, CT, and NG were detected in 6.5%, 10.4%, and 5.5% of swab samples, respectively. Regarding age, a significant difference was noticed for prevalence of NG and HSV between groups I and III. Because of public health importance of sexual transmitted diseases (STDs), their long-lasting impact on quality of life, and their economic burden, preventing measures and education of women seem necessary.

Changes in the selected reproductive health indicators among married women of reproductive age in low performing areas of Bangladesh: findings from an evaluation study. BMC Public Health 2014; 14:478. [PMID: 24886357 PMCID: PMC4037281 DOI: 10.1186/1471-2458-14-478] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2014] [Accepted: 05/14/2014] [Indexed: 11/10/2022] Open
Abstract
Background Three-year duration Demand-Based Reproductive Commodity Project (DBRHCP) was launched in three low performing areas: rural Nabiganj (population 323,357), Raipur (population 260,983) and urban slum in Dhaka (population 141,912). Objectives: Assessing changes in knowledge among married women of reproductive age on selected reproductive health issues and to explore their service utilization patterns over the project period in selected low performing areas of Bangladesh. Methods The study adopted a pre- posts design. In the project areas, the entire chain of service provision were modified through the interventions under the DBRHCP, including training of the providers, enhanced behavioral change communication activities, follow-up and counseling, record keeping, reporting and monitoring, as well as improvement in logistics and supplies. Peer promoters were established as linkages between clients and service providers. All households were enlisted. Baseline and end line surveys were done using representative simple random sampling method, capturing changes over one year intervention period. Descriptive analysis was done using SPSS package, version 10. Proportional tests using Stata, version 8 were done to assess changes from baseline to end line. Results The overall contraceptive prevalence was markedly different in the three study areas but significantly increased in both Dhaka urban slums and Nabiganj. In the rural areas, a higher proportion of the women in endline compared to baseline obtained contraceptive methods from the public sectors. Irrespective of study sites, significantly higher proportion of women received ANC (Antenatal Care) and PNC (Post natal care) in endline compared to baseline. In all study sites higher proportions of women were aware of maternal complications at endline. Services were obtained from qualified persons for reported symptoms of sexually transmitted infections by a higher proportion of women at endline compared to baseline. There were improvements in other RH indicators, such as use of skilled birth attendants and overall utilization of health care facilities by women. Conclusions The improvements in several important RH indicators in the intervention areas suggest that the interventions affected selected outcomes reported in the study. The study findings also suggest that investment in the reproductive health sector, particularly in existing government programs, improves RH outcomes.

Abstract
Despite being curable reproductive tract infections (RTIs) including sexually transmitted infections continue to be a major health problem in developing countries. The present study was undertaken to know the prevalence of trichomoniasis, vaginal candidiasis, genital herpes, chlamydiasis, and actinomycosis in rural and urban women of Haryana by using wet mount, PAP smear, and fluorescent microscopic examination. Patients suspected of suffering from bacterial vaginosis were given treatment and were not included in the study. RTIs were seen in 16.6% of urban and 28.7% of rural women. The highest prevalence seen was that of trichomoniasis in both rural (24.2%) and urban (15.7%) women, followed by candidiasis (4.2% in rural and 0.6% in urban women), genital herpes (0.3% in rural and 0.2% in urban women), and chlamydiasis (0.02% in rural and 0.05% in urban women). Pelvic actinomycosis was seen in 1.4% of rural and 0.06% of urban women using intrauterine contraceptive devices. Mixed infection of Trichomonas vaginalis with Candida spp. was seen in 6.3% of rural women only. It is desirable to have a baseline profile of the prevalence of various agents causing RTIs in a particular geographic area and population which will help in better syndromic management of the patients.

Abstract
This study used data from the Bangladesh Adolescents Survey 2005 to identify socioeconomic and urban-rural determinants of knowledge regarding sexually transmitted infections (STIs) including HIV/AIDS transmission. A cluster sampling of 11 986 adolescents was conducted from April to August 2005. Data were analyzed using SPSS applying principle component analysis, multivariate logistic regression analysis, and prevalence ratios (PRs) with 95% confidence intervals (CIs). Overall knowledge of transmission of STIs was poor (4.5%), showing urban adolescents having twice the knowledge of rural adolescents (PR = 1.9; 95% CI = 1.6-2.2). HIV/AIDS knowledge level was high (68%), with a 40% higher knowledge among urban adolescents (PR = 1.4; 95% CI = 1.3-1.4). Probability of knowledge of STIs and HIV/AIDS transmission was lowest in 12- to 14-year-old uneducated female household workers of the poorest socioeconomic status in rural settings (0.0002 and 0.064, respectively). The urban-rural factor was more important than the socioeconomic factor. Health promotion and education programs can play an important role in improving the sexual reproductive health knowledge situation.

Abstract
OBJECTIVES To assess the prevalence and associated risk factors of syphilis among antenatal clinic attendees by a multi-center cross-sectional study in Karachi, Pakistan. METHODS We administered a structured questionnaire and obtained a blood sample for syphilis serology (rapid plasma reagin test with Treponema pallidum hemagglutination assay confirmation) from all women giving informed consent over six weeks in 2007. Prevalence was calculated at 95% confidence intervals. Multivariate analysis was adapted to assess risk factors. RESULTS There were seven (0.9%) confirmed cases of syphilis (95% CI: 0.4, 1.8) in a sample size of 800 women recruited from three urban sites (-1% refusal rate). Women who lived in an area where male drug use is prevalent had 1.5% higher prevalence rates than women from the other two sites 0.5%. CONCLUSIONS We documented higher-than-expected syphilis seroprevalence rates in a low risk population of antenatal clinic attendees in Pakistan. Bridge populations for syphilis may include drug users, who are usually married, and Hijras or their clients. In accordance with our results, the national policy for syphilis control in Pakistan should be modified to include universal syphilis screening in antenatal clinics with subsequent partner notification.

Abstract
AIM The aim of this study was to investigate the seroprevalence of antibody to Treponema pallidum among pregnant women and its association with age, sexual behavior and socioeconomic status. MATERIALS AND METHODS In this cross-sectional study, 1266 sera were collected from pregnant women attending Bangabandhu Sheikh Mujib Medical University and Rajshahi, Khulna and Chittagong Medical College Hospitals between February 2007 and April 2008. From each hospital, samples were collected from about a quarter of the total recruited pregnant women. Sera were tested to identify the antibody to T. pallidum using Treponema pallidum hemagglutination at the Virology Department of Bangabandhu Sheikh Mujib Medical University. Logistic regression was used to explore potential risk factors for syphilis. RESULTS Among 1250 sera tested (16 sera were discarded due to hemolysis), 37 (2.96%) were positive for T. pallidum antibody. Higher seropositivity was associated with couples with no formal education, low socioeconomic status (P = 0.006), marriage at or before 18 years of age (P = 0.002), multiple marriages of the husband (P = 0.031) and sexual activity for more than 10 years (P = 0.007). Among these factors, low education level of women, early age of marriage and multiple marriages of the husband showed individual effects on high seropositivity to T. pallidum. CONCLUSIONS The high seroprevalence of syphilis among pregnant women attending the antenatal clinics of these hospitals indicates the need for the incorporation of screening for syphilis in routine antenatal screening in Bangladesh. Improvement of education level in the female population, prevention of early marriage and preventing polygamy of husbands may play an important role in prevention of syphilis among women.

Abstract
Herpes simplex virus type-2 (HSV-2) has been identified as a possible aetiological agent of cancer in humans, especially prostate cancer, but results remain controversial. Here, we have addressed this question using a medical geography approach based on the national incidence of various cancers and seroprevalence of HSV-2 in 64 countries worldwide. We corrected reports of cancer incidence for national gross domestic product (GDP) because living in a wealthy nation likely increases the probability of having a cancer detected. Data were also corrected for latitude and diet. Our analysis not only confirms that prostate cancer and HSV-2 seroprevalence are positively associated, but it also reveals the existence of a positive relationship between HSV-2 and melanoma incidence in both men and women. These results, though correlational, suggest that HSV-2 should continue to be investigated as a possible oncogenic pathogen of humans.

Abstract
BACKGROUND HIV prevalence is low in the Middle East and North Africa (MENA) region, though the risk or potential for further spread in the future is not well understood. Behavioral surveys are limited in this region and when available have serious limitations in assessing the risk of HIV acquisition. We demonstrate the potential use of herpes simplex virus-2 (HSV-2) seroprevalence as a marker for HIV risk within MENA. METHODS We designed a mathematical model to assess whether HSV-2 prevalence can be predictive of future HIV spread. We also conducted a systematic literature review of HSV-2 seroprevalence studies within MENA. RESULTS We found that HSV-2 prevalence data are rather limited in this region. Prevalence is typically low among the general population but high in established core groups prone to sexually transmitted infections such as men who have sex with men and female sex workers. Our model predicts that if HSV-2 prevalence is low and stable, then the risk of future HIV epidemics is low. However, expanding or high HSV-2 prevalence (greater than about 20%), implies a risk for a considerable HIV epidemic. Based on available HSV-2 prevalence data, it is not likely that the general population in MENA is experiencing or will experience such a considerable HIV epidemic. Nevertheless, the risk for concentrated HIV epidemics among several high-risk core groups is present. CONCLUSIONS HSV-2 prevalence surveys provide a useful mechanism for identifying and corroborating populations at risk for HIV within MENA. HSV-2 serology offers an effective tool for probing hidden sexual risk behaviors in a region where quality behavioral data are limited.

Abstract
OBJECTIVES This study evaluated the role of single session counselling on partner referral among index cases diagnosed as having sexually transmitted infections (STIs) in Bangladesh. METHODS A quasirandomised trial was conducted in 1339 index cases with symptomatic STIs in 3 public and 3 non-government organisation operated clinics. RESULTS Out of 1339 index cases, partner referral was achieved by 37% in the counselling group and 27% in the non-counselling group. Index cases in the counselling group and non-counselling group were similar in terms of condom use rates, STI symptoms and duration of disease. A quarter of the index cases reported having more than one sex partner in last 3 months, and 39% reported having commercial sex partners. Only 8% of the index cases reported using condoms during their last sex act. Partner referral rates were higher among index clients with higher age, higher income, those who attended NGO clinics, those who had only one partner and among those who had no commercial partners, but counselling had significantly positive impact in all of these subgroups. In multivariate analysis, the probability of partner referral was 1.3 times higher among index cases in the counselling group (prevalence ratio 1.3; 95% CI 1.1 to 1.6) as compared to index cases in the non-counselling group. CONCLUSIONS Patient-oriented single session counselling was found to have a modest but significant effect in increasing partner referral for STIs in Bangladesh, greater emphasis should be placed on examining further development and dissemination of partner referral counselling in STI care facilities.

Prevalence and risk factors of hepatitis B and C virus infections in an impoverished urban community in Dhaka, Bangladesh. BMC Infect Dis 2010; 10:208.

Abstract
Background Viral hepatitis is a serious global public health problem affecting billions of people globally, and both hepatitis B virus (HBV) and hepatitis C virus (HCV) infections are rapidly spreading in the developing countries including Bangladesh due to the lack of health education, poverty, illiteracy and lack of hepatitis B vaccination. Also there is lack of information on their prevalence among the general population. So, a population-based serological survey was conducted in Dhaka to determine the prevalence and risk factors of HBV and HCV infections. Methods Healthy individuals were selected for demographic and behavioural characteristics by stratified cluster sampling and blood tested for hepatitis B surface antigen (HBsAg), antibody to HBV core antigen (anti-HBc), and anti-HCV antibodies (anti-HCV). Results From June 2005-November 2006, 1997 participants were screened for HBsAg, anti-HBc and anti-HCV, 738 (37%) were males with mean (SD) age of 24 (14) years. HBV-seropositivity was documented in 582 (29%) participants: 14 (0.7%) were positive for HBsAg, 452 (22.6%) for anti-HBc and 116 (5.8%) for both HBsAg and anti-HBc. Four (0.2%) participants were positive for anti-HCV, and another five (0.3%) for both anti-HBc and anti-HCV. Ninety-six/246 (39%) family members residing at same households with HBsAg positive participants were also HBV-seropositive [74 (30.1%) for anti-HBc and 22 (8.9%) for both HBsAg and anti-HBc], which was significantly higher among family members (39%) than that of study participants (29%) (OR 1.56; p < 0.001). In bivariate analysis, HBV-seropositivity was significantly associated with married status (OR 2.27; p < 0.001), history of jaundice (OR 1.35; p = 0.009), surgical operations (OR 1.26; p = 0.04), needle-stick injuries (OR 2.09; p = 0.002), visiting unregistered health-care providers (OR 1.40; p = 0.008), receiving treatment for sexually transmitted diseases (STD) (OR 1.79; p = 0.001), animal bites (OR 1.73; p < 0.001); ear-nose-body piercing in females (OR 4.97; p < 0.001); circumcision (OR 3.21; p < 0.001), and visiting community barber for shaving in males (OR 3.77; p < 0.001). In logistic regression analysis, married status (OR 1.32; p = 0.04), surgical operations (OR 1.39; p = 0.02), animal bites (OR 1.43; p = 0.02), visiting unregistered health-care providers (OR 1.40; p = 0.01); and ear-nose-body piercing in females (OR 4.97; p < 0.001) were significantly associated with HBV-seropositivity. Conclusions The results indicate intermediate level of endemicity of HBV infection in Dhaka community, with much higher prevalence among family members of HBsAg positive individuals but low prevalence of HCV infections, clearly indicating need for universal hepatitis B vaccination. The use of disposable needles for ear-nose-body piercing need to be promoted through public awareness programmes as a preventive strategy.

Abstract
OBJECTIVE To investigate herpes simplex virus type-2 (HSV-2) seropositivity and associated risk factors in Vietnamese women. METHODS Cross-sectional study with personal interviews and gynecological examinations among population-based samples of ever married women, aged 15 to 69 years, living in Ho Chi Minh City (HCMC) and Hanoi in 1997. Type-specific IgG antibodies against HSV-2 were detected using HerpeSelect ELISA (Focus Diagnostics). Adjusted prevalence ratios were estimated with log-binomial regression. RESULTS HSV-2 seroprevalence was higher in 1106 women from HCMC (30.8%, 95% CI: 28.1-33.4, age-standardized to 2000 world standard population) than in 1170 women from Hanoi (8.8%, 95% CI: 7.1-10.5). In HCMC, HSV-2 seroprevalence was higher for women who were not married, HPV DNA positive, current hormonal contraceptive users, or had a history of multiple sexual partners or spontaneous abortion. HCMC seroprevalence was inversely associated with educational attainment, age at first intercourse, and age at first pregnancy. In the multivariable model for HCMC, a trend of increasing HSV-2 seroprevalence with age was observed, and prevalence ratios were nearly identical to age-adjusted prevalence ratios for marital status, age at first pregnancy, and HPV DNA positivity. CONCLUSIONS HSV-2 was notably less prevalent in Hanoi than HCMC, where it was associated with traditional HSV-2 risk factors. These results are likely explained by socio-cultural, historical, economic, and demographic factors related to urban-rural and regional differences. Future population-based studies should include men and never-married women as a next step toward obtaining a more nearly complete picture of HSV-2 epidemiology in Vietnam.

This is a simple random sampling cross sectional study that was performed on 312 addicted prisoner men at Khazarabad addicts' prison in Sari/Iran in September 2001. Their blood samples were examined through third generation enzyme immunoassay. Data were collected through questionnaires and interview. Associated risk factors were compared in 82 hepatitis C antibody positive addicts (the affected group) and 148 hepatitis C antibody negative addicts (the unaffected group). Out of 312 addicted prisoners, 96 were hepatitis C anti body positive. The seroprevalence of hepatitis C infection was found to be 30.8%. Major associated risk factors in the affected group were as follows: duration of addiction, duration of imprisonment (mean 48 months), route of drug administration, length of alcohol consumption, tattooing, shared usage of needles and razors, multiple sexual partners and type of drugs (p < 0.05). On multivariate logistic regression analysis these factors were found to be significant independent risk factors for HCV infection: tattooing (OR 100, 95% CI), multiple sexual partners (OR 4.97, 95% CI) and history of surgery (OR 6.23, 95% CI). It is concluded that hepatitis C infection had a considerable prevalence in addicted prisoners. High risk and unsafe behaviors were found to be the main factors of contamination.

Abstract
The objective of the study was to determine the prevalence of Mycoplasma genitalium in a sample of health clinic attendees complaining of vaginal discharge. A subsample of 399 vaginal and cervical swabs was randomly selected from 2579 samples collected during a study to determine the causes of vaginal discharge in women attending primary health-care clinics in Dhaka, Bangladesh. Cervical samples were tested for M. genitalium by polymerase chain reaction. In addition, the samples were tested for Chlamydia trachomatis, Neisseria gonorrhoeae, Trichomonas vaginalis, bacterial vaginosis and candida. M. genitalium was detected in three samples (0.8%; 95% confidence interval: 0.00–1.6). The prevalence of C. trachomatis, N. gonorrhoeae T. vaginalis, bacterial vaginosis and candida was 1.3, 3.8, 8, 23.25 and 32.5%, respectively. Two women with M. genitalium were co-infected with T. vaginalis or candida. This is the first study to document the existence of M. genitalium in Bangladesh. Although the prevalence of this infection is low in the population tested, further research into this pathogen in other Bangladeshi populations is justified.

Abstract
Bangladesh initiated an early response to the HIV epidemic starting in the mid-1980s. Since then, the response has been enhanced considerably, and many HIV-prevention interventions among the most at-risk populations and the general youth are being undertaken. Alongside prevention activities, gathering of data has been a key activity fostered by both the Government and individual development partners. This paper reviews available sources of data, including routine surveillance (HIV and behavioural among most at-risk populations), general population surveys, and various research studies with the aim to understand the dynamics of the HIV epidemic in Bangladesh. Available data show that the HIV epidemic is still at relatively low levels and is concentrated mainly among injecting drug users (IDUs) in Dhaka city. In addition, when the passively-reported cases were analyzed, another population group that appears to be especially vulnerable is migrant workers who leave their families and travel abroad for work. However, all sources of data confirm that risk behaviours that make individuals vulnerable to HIV are high--this is apparent within most at-risk populations and the general population (adult males and youth males and females). Based on the current activities and the sources of data, modelling exercises of the future of the HIV epidemic in Dhaka suggest that, if interventions are not enhanced further, Bangladesh is likely to start with an IDU-driven epidemic, similar to other neighbouring countries, which will then move to other population groups, including sex workers, males who have sex with males, clients of sex workers, and ultimately their families. This review reiterates the often repeated message that if Bangladesh wants to be an example of how to avert an HIV epidemic, it needs to act now using evidence-based programming.

Abstract
Bangladesh has been conducting annual serological surveillance for HIV and syphilis since 1998 among most at-risk populations including sex workers, males having sex with males, injecting drug users (IDUs) and heroin smokers. During the seventh round conducted between January and June 2006, 10,368 people were sampled and the overall HIV prevalence was 0.9%. The highest HIV rate was recorded in male IDUs from the capital city Dhaka (7%), and the rates have risen significantly over the rounds (P < 0.001). In Dhaka, most of the HIV-positive IDUs (10.5%) were localized in one neighbourhood, while in the remaining neighbourhoods 1% were positive (P < 0.001). In all other groups, HIV prevalence was <1%. Active syphilis rates were highest in female IDUs (9.9%) followed by female street-based sex workers (8.6%). However, rates in female sex workers in Dhaka declined significantly over the years (P < 0.001). Bangladesh has to act urgently to prevent escalation of the epidemic.

Abstract
OBJECTIVE To determine the seroprevalence of human immunodeficiency virus (HIV), hepatitis B and C viruses (HBV, HCV), and herpes simplex virus type 2 (HSV-2) in the tribal population of central India. METHODS A community-based cross-sectional survey was carried out in the tribal population of Jabalpur district. Blood samples were drawn from 326 patients with sexually transmitted infections (STIs) and 526 randomly selected adults. These were tested for HIV, HBV, HCV, and HSV-2 using commercial ELISA kits. RESULTS The prevalence of IgG antibodies to HSV-2 was 20.8% in STI patients compared to 12.4% in the general population. The HBV carriage rate was 3.4% in STI patients against 2.9% in the general population. HCV prevalence was 3.9% in STI patients and 4.6% in the general population. No HIV infection was found in the study population. CONCLUSIONS In view of the high prevalence of viral STIs in the tribal community of Central India, there is a need to strengthen the STI control program in this under-privileged group.

Abstract
The aim of this study was to detect the sensitivity and specificity of rapid syphilis diagnostic tests (immunochromatographic strip [ICS] test and rapid test device [RTD]) performed by low-skilled paramedics in field clinics and by highly-skilled technologists in laboratories and compare them with the gold standard (rapid plasma reagin [RPR] and Treponema pallidum haemagglutination [TPHA]) tests for diagnosis of syphilis. A cross-sectional study was conducted among female sex workers (FSWs) in Dhaka, Bangladesh, from August 2004 to July 2005. Blood specimens were tested for syphilis using (i) ICS, (ii) RTD, (iii) RPR tests performed by low-skilled paramedics; and (i) ICS, (ii) RTD, (iii) RPR and (iv) TPHA tests by highly-skilled technologists. The sensitivity and specificity of the ICS and RTD test performed by low- and highly-skilled personnel were compared with the gold standard. A total of 684 FSWs were enrolled and the prevalence of syphilis among FSWs was 20.8% as determined by the gold standard. There was no significant difference in the performance of ICS test done by paramedics in the field when compared with the gold standard performed by highly-skilled technologists in the laboratory (sensitivity, 94.45%; specificity, 92.6%). The ICS test could fulfil the need for a non-invasive, rapid screening test for syphilis.

Abstract
This article presents the status of rural Bangladeshi adolescent girls' awareness about reproductive health. Analysis of data revealed that a sizable proportion of adolescent girls had incorrect knowledge or misconceptions about the fertile period, reproduction, sexually transmitted diseases, and HIV/AIDS. Age, education either of adolescents or their mothers, residence, and exposure to mass media were the significant predictors of adolescent girls' knowledge about reproductive health. Strong efforts are needed to improve awareness and to clarify misconceptions about reproductive health. Improved access to mass media and education could improve rural Bangladeshi adolescent girls' awareness about reproductive health.

Abstract
To determine the characteristics of seroprevalence of herpes simplex virus type 2 (HSV-2) infection among Korean people, a cross-sectional study was conducted on three groups in 2004. The three groups consisted of the general public who visited public health centers, commercial sex workers (CSWs), and human immunodeficiency virus (HIV)-infected persons. Among the general public, HSV-2 seroprevalence rates for age under the 20s, in the 20s, 30s, 40s and the above 22.6%, 32.7% and 32.3%, respectively, which showed rapid increase of the rate in the 30s (p<0.0001). In case of the above of 19 yr old, women (28.0%) was higher than men (21.7%) (p<0.0001). The rate of CSWs (81.6%) was about 10 times higher than that of general women. In case of HIV-infected men (47.6%), the figure was about 2-3 times higher than that of general men. The low rate in the teens and the 20s proved that it is essential to develop sexually transmitted infections (STIs) prevention programs of education and publicity for them as a precaution measure. This study is the first major study of its kind on HSV-2 and would provide basic data for prevention of STIs including information about target groups subject to vaccination program.

Abstract
OBJECTIVE The objective of this study was to estimate the prevalence and correlates of herpes simplex virus type 2 infection in women in an antenatal clinic in the South Pacific island nation of Vanuatu. STUDY DESIGN A prevalence survey of sexually transmitted infections of pregnant women attending an antenatal clinic at Vila Central Hospital was conducted in 1999-2000. Serum samples were tested for HSV-1 and HSV-2 antibodies by enzyme-linked immunosorbent assay. Results for other sexually transmitted infections and demographic and obstetric variables were analyzed for their association with HSV-2 serostatus. RESULTS HSV-2 serum antibody results were obtained on 535 women and HSV-1 results on 134. The seroprevalence of HSV-2 was 30% and HSV-1 was 100%. On multivariate analysis, the independent predictors of HSV-2 infection were age, marital status, and trichomoniasis. CONCLUSIONS HSV-2 was common in this sample of sexually active women in Vanuatu. This is the first study of HSV in Vanuatu and one of very few studies in the Pacific region.

Abstract
OBJECTIVES This study aimed to ascertain the prevalence of sexual risk behavior among married men and women who had, or had not, lived apart from their spouse as a result of the husbands' work migration. METHODS A cross-sectional survey was conducted among a random sample of 1,175 married women and 703 married men in 2 rural areas of Bangladesh. RESULTS Extramarital sex was reported by 64.2% (95% confidence interval [CI] = 58.7-69.7) of 296 men and 8.6% (95% CI = 7.6-9.6) of 779 women who had lived apart from their spouse, 2 to 3 times higher than the proportions among those who had not lived apart (P <0.05). The proportions of men who reported sex with a female sex worker (50.7%; 95% CI = 45.0-56.4) or with another male (5.4%; 95% CI = 2.8-8.0), while living away, were double the proportions reporting they had done so before living away or among men who had not lived away (P <0.05). Only 2 men had ever used had a condom during sex with another male, and less than one third of men had used a condom during sex with a sex worker or during marital sex. CONCLUSIONS The sexual risk behavior of married men living away from home may put themselves and their wives at risk for HIV infection and other sexually transmitted diseases.

Abstract
OBJECTIVES/GOAL Data on prevalence of herpes simplex virus type 2 (HSV-2) infections are limited in Asia. This study investigated the seroprevalence of, and risk factors for, antibodies to HSV-2 among low- and high-risk, predominantly asymptomatic populations in Indonesia. STUDY DESIGN We screened women attending maternal and child health, obstetric, gynecology, and sexually transmitted infection (STI) clinics; men attending STI clinics; and female sex workers (FSWs) for type-specific HSV-2 antibodies using the HerpesSelect 2 enzyme-linked immunosorbent assay IgG and Western blot. RESULTS HSV-2 antibodies were detected in 153 of 176 FSWs (86.9%; 95% confidence interval [CI], 81.0-91.5); increasing age was the only significant independent risk factor (odds ratio [OR], 1.15; 95% CI, 1.06-1.24; P = 0.001). Among non-sex worker females, HSV-2 antibodies were detected in 78 of 418 (18.7%; 95% CI, 15.0-22.7); significant independent associations were any contraceptive use (OR, 2.24, 95% CI = 1.33-3.85, P = 0.003), symptoms or signs of genital ulcer (OR, 2.69; 95% CI, 1.27-5.70; P = 0.01) and younger age of sexual debut (OR, 0.92; 95% CI, 0.86-0.99; P = 0.03). HSV-2 antibodies were detected in 25 of 116 men (21.6%; 95% CI, 14.5-30.1). CONCLUSIONS HSV-2 seroprevalence reported here is in the upper range of that reported in nearby regions. Health promotion is needed to encourage affected individuals to recognize symptoms of genital herpes and seek care and advice on reducing transmission. The high seroprevalence among FSWs has potentially serious implications for the HIV epidemic in Indonesia.

Abstract
OBJECTIVE This study was conducted to determine the prevalence of selected sexually transmitted infections (STIs) and their risk factors among workers in and near a truck stand in Dhaka, Bangladesh. STUDY DESIGN A random sample of 696 men and 206 women were recruited into a cross-sectional study using a census that enumerated transport agents, motor mechanics, laborers, and vendors in Tejgaon truck stand. RESULTS The prevalence rates of syphilis (rapid plasma reagin and Treponema pallidum hemagglutination), gonorrhea (polymerase chain reaction [PCR]), and chlamydial infections (PCR) among men were 4.1%, 7.7%, and 2.3%, respectively, and among women were 2.9%, 8.3%, and 5.2%. Multivariable analysis revealed that having >or=2 sex partners in the last month, never using a condom with sex workers, and ever injecting narcotics were significant predictors of STI among men. Being never married, working as a laborer, older age, and living within the truck stand were significant predictors of practicing high-risk behaviors among men, but none predicted infection with STIs. CONCLUSIONS Both behavioral and STI data suggest that truck stand workers should be included in the STI/HIV intervention programs.

Abstract
BACKGROUND Studies demonstrating previous herpes simplex virus (HSV) type 2 infection as a risk factor for HIV transmission, and the development of a HSV vaccine candidate, have emphasised the need for worldwide population based studies of HSV seroprevalence. The only nationwide seroprevalence studies have been conducted in the United States. METHODS An Australia-wide, population based study of HSV-1 and HSV-2 seroprevalence was conducted, using serum and sociodemographic data collected between 1999-2000, for a representative study of risk factors for diabetes in over 11 000 adults. A stratified random sample of 4000 was tested for HSV-2 and 1000 for HSV-1, with sampling and weighting for various demographic factors. RESULTS Seroprevalence of HSV-2 in Australian adults was 12%. Prevalence in women (16%) was twice that in men (8%). Rural populations had a lower prevalence (9%) than metropolitan (13%), and Indigenous had a higher prevalence (18%) than the non-Indigenous populations (12%). The seroprevalence of HSV-1 was 76% with significant differences by age group, sex and Indigenous status. CONCLUSION These are the first nationwide data to compare with US studies. HSV-2 infection is less common in Australia than the United States, and this will allow planning for combating HIV transmission in high prevalence populations in northern Australia. In addition, the high HSV-1 seroprevalence will be important for future deployment of genital herpes vaccines.

Abstract
UNLABELLED OBJECTIVE AND GOAL: The goal of this study was to study the prevalence of sexually transmitted infections (STIs)/reproductive tract infections (RTIs) among brothel-based sex workers (SWs) in Bangladesh. STUDY A cross-sectional study was conducted among SWs in 4 randomly selected brothels. A sociodemographic and behavioral survey and pelvic examination was conducted. Specimens including endocervical swab, high vaginal swab, and blood were collected and were examined for Neisseria gonorrhoeae, Chlamydia trachomatis, Trichomonas vaginalis, bacterial vaginosis candidiasis, and syphilis. RESULTS A total of 439 SWs were enrolled and 49.6% had genital symptoms. Among all SWs, 17.5% were positive for N. gonorrhoeae; 15.5% for C. trachomatis; 7.5% for T. vaginalis, and 6.6% had active syphilis. A total of 67.4% SWs were positive for at least 1 cervical and/or vaginal infection. CONCLUSION The prevalence of STIs/RTIs among SWs in brothels in Bangladesh is high. An intervention strategy addressing both symptomatic and asymptomatic infections and periodic screening of SWs for RTIs/STIs is essential for successful HIV and STIs prevention programs.

Abstract
The prevalence of sexually transmitted infections (STIs) and reproductive tract infections (RTIs) among hotel-based sex workers (HBSWs) in Dhaka, Bangladesh, was studied. A total of 400 HBSWs were enrolled in the study during April to July 2002. Endocervical swabs, high vaginal swabs, and blood samples from 400 HBSWs were examined for Neisseria gonorrhoeae (by culture), Chlamydia trachomatis (by PCR), Trichomonas vaginalis (by microscopy), antibody to Treponema pallidum (by both rapid plasma reagin and Treponema pallidum hemagglutination tests), and antibody to herpes simplex virus type 2 (HSV-2) (by enzyme-linked immunosorbent assay). Sociodemographic information as well as gynecological and obstetric information was collected. Among the HBSWs, 228 women (57%) were symptomatic and 172 (43%) were asymptomatic, 35.8% were positive for N. gonorrhoeae, 43.5% were positive for C. trachomatis, and 4.3% were positive for T. vaginalis. A total of 8.5% had syphilis, 34.5% were positive for HSV-2, and 86.8% were positive for at least one RTI or STI. There was no significant difference between the prevalences of STIs among the symptomatic and asymptomatic HBSWs. These data suggested a high prevalence of STIs, particularly gonorrhea and chlamydia, among HBSWs in Dhaka.

Abstract
Information on age- and sex-specific prevalence of herpes simplex virus (HSV) types 2 and 1 infections is essential to optimize genital herpes control strategies, which increase in importance because accumulating data indicate that HSV-2 infection may increase acquisition and transmission of human immunodeficiency virus. This review summarizes data from peer-reviewed publications of type-specific HSV seroepidemiologic surveys. HSV-2 prevalence is, in general, highest in Africa and the Americas, lower in western and southern Europe than in northern Europe and North America, and lowest in Asia. HSV-2 and -1 prevalence, overall and by age, varies markedly by country, region within country, and population subgroup. Age-specific HSV-2 prevalence is usually higher in women than men and in populations with higher risk sexual behavior. HSV-2 prevalence has increased in the United States but national data from other countries are unavailable. HSV-1 infection is acquired during childhood and adolescence and is markedly more widespread than HSV-2 infection. Further studies are needed in many geographic areas.

Abstract
Genital herpes, which was considered to be a minor sexually transmitted disease (STD) in the past in developing countries, is rapidly increasing; in contrast, bacterial STDs are declining. This changing trend of various STDs prompted us to analyze our data retrospectively to see whether a similar change is occurring in this part of India as well. The records of sexually transmitted diseases (STDs) clinic attendees from January 1977 to December 2000 were analyzed. The demographic profile of patients with genital herpes was also considered for analysis. STDs were diagnosed clinically and by appropriate laboratory tests wherever applicable. VDRL test was done in all patients, and HIV antibody detection was performed from 1987 onwards. The incidences of chancroid, donovanosis, and gonorrhea were 12.2%, 6.3%, and 16.9%, respectively, from January 1977 to December 1985. The figures for the same decreased to 2.5%, 0.9%, and 2.3%, respectively, from January 1993 to December 2000. The decreasing incidence of the above bacterial STDs is statistically significant (p<0.001). However, there was an approximately two-fold increase in the incidence of genital herpes in recent years (20.5%) in comparison to the figures from the late 70s (11.4%). Molluscum contagiosum also showed an upward trend (1% in 1977-85 vs. 9.8% in 1993-2000). Condylomata accuminata remained almost unchanged (21.4% in 1977-85 vs. 20% in 1993-2000). To conclude, a significant increase in the number of viral STDs and a decline in the bacterial diseases were observed in recent years in comparison to the figures from the late 70s. This may be due to awareness of HIV, success of control programs, syndromic management of STDs, and adoption of safer sexual practices, which prevent bacterial STDs more efficiently than viral ones.
