J Public Health (Oxf) 2023; 45:e630-e638. [PMID: 37477242 DOI: 10.1093/pubmed/fdad130] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2022] [Revised: 06/09/2023] [Indexed: 07/22/2023] Open
Abstract
BACKGROUND The objectives of this study were to determine the association between the vulnerability factors linked to human immunodeficiency virus (HIV) and other sexually transmitted infection among the young women who sell sex (YWSS) group (15-24 years) and adult sex workers, engaged in consensual sex for money (AFSW). METHODS A cross-sectional study was conducted among AFSW involved in commercial sex transactions. Prevalence ratios (PR) analysis was carried out using log-binomial regression model. RESULTS The prevalence of HIV-1 was 29.4% among YWSS compared to 19.6% among female sex worker (PR = 1.43 [1.07-1.91]). Consistent condoms use last 3 months were very low at 22.3% and 41.2%, respectively (PR = 0.52 [0.37-0.74]), the low education level among YWSS versus AFSW (PR = 0.55 [0.40-0.76]); YWSS having been a victim of sexual violence in the last 12 months (PR = 2.00 [1.52-2.63]), were also more likely to be HIV positive. CONCLUSIONS The YWSS had a high prevalence of HIV, experienced other socioeconomic vulnerabilities and remain a key population for comprehensive HIV programs. To reach all YWSS, programs need to consider many outreach programs and address the shared determinants of HIV risk.

Longo JDD, Woromogo SH, Diemer HSC, Tékpa G, Belec L, Grésenguet G. Incidence and risk factors for tuberculosis among people living with HIV in Bangui: A cohort study. PUBLIC HEALTH IN PRACTICE 2022; 4:100302. [PMID: 36570403 PMCID: PMC9773039 DOI: 10.1016/j.puhip.2022.100302] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2022] [Revised: 07/06/2022] [Accepted: 07/20/2022] [Indexed: 12/27/2022] Open
Abstract
Objectives The objectives of this study were to determine the incidence and risk factors of tuberculosis (TB) among people living with HIV (PLHIV). Methods A cohort study was carried out in an HIV infection management centre in Bangui. PLHIV aged 18 or older, with no history of TB, enrolled between January 1, 2017 and December 31, 2018 were included in the study. The chi-square test was used only to compare the proportions at the 5% significance level. To determine the risk factors, we used the Cox regression adjusted hazard ratio, using Epi Info 7 software. Results A total of 677 patients including 618 (91.28%) on antiretroviral therapy were included in the study. The median age was 34 with extremes ranging from 18 to 57. Of the patients followed, 104 developed TB. The overall incidence of TB was 15.37 (104/677) cases per 100 PLHIV-years. This incidence was 13.10 (81/618) cases per 100 in patients on ART-years and 38.99 (23/59) cases per 100 patients on pre-ART-years. In pre-ART patients the incidence of TB was therefore almost 3 times higher than that of PLHIV on ART (p = 0.03). WHO clinical stages III and IV (p = 0.02), absence of ART (p = 0.03), poor adherence (p = 0.004) and low functional capacity (p = 0.04) were the risk factors associated with the occurrence of TB among PLHIV in Bangui. Conclusions The high incidence of TB in our context is essentially linked to delay in diagnosis and the quality of care. Early initiation of antiretroviral therapy, systematic screening for TB in PLHIV upon entry into the active queue and better monitoring of patients on ART are strongly recommended.

Unexpected high frequency of unspecific reactivities by testing pre-epidemic blood specimens from Europe and Africa with SARS-CoV-2 IgG-IgM antibody rapid tests points to IgM as the Achilles heel. J Med Virol 2020; 93:2196-2203. [PMID: 33107601 DOI: 10.1002/jmv.26628] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2020] [Revised: 10/12/2020] [Accepted: 10/23/2020] [Indexed: 12/15/2022]
Abstract
We aimed to evaluate the rates of false-positive test results of three rapid diagnostic tests (RDTs) for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-specific immunoglobulin G (IgG) and IgM detection. Two serum panels from patients hospitalized in Paris, France, and from patients living in Bangui, Central African Republic, acquired before the 2019 COVID-19 outbreak, were tested by 3 CE IVD-labeled RDTs for SARS-CoV-2 serology (BIOSYNEX® COVID-19 BSS [IgG/IgM]; SIENNA™ COVID-19 IgG/IgM Rapid Test Cassette; NG-Test® IgG-IgM COVID-19). Detectable IgG or IgM reactivities could be observed in 31 (3.43%) of the 902 IgG and IgM bands of the 3 RDTs used with all pre-epidemic sera. The frequencies of IgG/IgM reactivities were similar for European (3.20%) and African (3.55%) sera. IgM reactivities were observed in 9 European and 14 African sera, while IgG reactivity was observed in only 1 African serum (15.1% vs. 0.66%). The test NG-Test® IgG-IgM COVID-19 showed the highest rates of IgG or IgM reactivities (6.12% [18/294]), while the test BIOSYNEX® COVID-19 BSS (IgG/IgM) showed the lowest rate (1.36% [4/294]). Some combinations of 2 RDTs in series allowed decreasing significantly the risk of false-positive test results. Our observations point to the risk of false-positive reactivities when using currently available RDT for SARS-CoV-2 serological screening, especially for the IgM band, even if the test is CE IVD-labeled and approved by national health authorities, and provide the rational basis for confirmatory testing by another RDT in case of positive initial screening.

Abstract
Classification of professional and non-professional female sex workers (FSWs) into different categories, never previously reported in the Central African Republic (CAR), may be useful to assess the dynamics of the human immunodeficiency virus (HIV) epidemic, design operational intervention programmes to combat HIV and other sexually transmitted infections (STIs) and to adapt these programmes to the broad spectrum of sexual transactions in the CAR. Our study proposes a socio-behavioural classification of FSWs living in the CAR and engaged in transactional and commercial sex. Thus, the aims of the study were these: (i) to categorize FSWs according to socio-anthropologic criteria in Bangui and (ii) to examine the association between a selection of demographic and risk variables with the different categories of female sex work as an outcome. A cross-sectional questionnaire survey was conducted in 2013 to describe the spectrum of commercial sex work (CSW) in Bangui among 345 sexually active women having more than 2 sexual partners, other than their regular partner, during the prior 3 months and reporting to have received money or gifts in return for their sexual relationships. According to socio-behavioural characteristics, FSWs were classified into six different categories. Professional FSWs, constituting 32.5% of the interviewed women, were divided in two categories: pupulenge (13.9%), i.e., dragonflies (sometimes called gba moundjou, meaning literally look at the White) consisting of roamers, who travel around the city to hotels and nightclubs seeking wealthy clients, with a preference for French men; and the category of kata (18.6%), i.e., FSWs working in poor neighbourhoods. Non-professional FSWs, constituting 67.5% of the interviewed women, were divided into four categories: street and market vendors (20.8%), students (19.1%), housewives (15.7%) and unskilled civil servants (11.9%). In general, CSW in the CAR presents a remarkably heterogeneous phenomenon. Risk-taking behaviour regarding STI/HIV infection appears to be different according to the different categories of female CSW. The groups of katas and street vendors were poorer and less educated, consumed more alcohol or other psycho-active substances (cannabis, tramadol and glue) and, consequently, were more exposed to STI. Our results emphasise the high level of vulnerability of both poor professional FSWs (kata) and non-professional sex workers, especially street vendors, who should be taken into account when designing prevention programmes targeting this population for STI/HIV control purposes.

Abstract
Adult outpatients attending the main sexually transmitted infection clinic of Bangui, Central African Republic, were prospectively subjected to a multiplex rapid diagnostic test for human immunodeficiency virus (HIV), hepatitis B virus (HBV), and hepatitis C virus (HCV). In group I (n = 208) of patients already followed for HIV, 6 (2.9%) were unexpectedly negative, thus corresponding to false positive for HIV by the national HIV algorithm; hepatitis B surface antigen and HCV positivities were high (18.7% and 4.3%, respectively). In group II (n = 71) of patients with unknown HIV status, at least 1 chronic viral disease was diagnosed in 26 (36.6%) patients, including 5 (7.1%) HIV, 17 (23.9%) HBV, and 3 (4.2%) HCV infections.

Abstract
Background: Opportunities for HIV testing could be enhanced by offering HIV self-testing (HIVST) in populations that fear stigma and discrimination when accessing conventional HIV counselling and testing. Field experience with HIVST was poorly reported in French-speaking African countries. Objective: To investigate the usability of HIVST in Bangui, Central African Republic. Methods: The prototype self-test Exacto® Test HIV (Biosynex, Strasbourg, France) was used to assess the usability of HIVST in 300 adults living in Bangui, according to WHO technical recommendations. Simplified and easy-to-read leaflet was translated in French and Sango. Results: Preliminary survey in 3,484 adult volunteers including students, men who have sex with men and female sex workers living in Bangui showed that previous HIV testing in conventional centres for HIV counselling and testing was relatively infrequent and that acceptability of HIVST was elevated, although high heterogeneity could be observed between groups. The notice in French and Sango of Exacto® Test HIV were chosen in 242/300 (80.6%) and 58/300 (19.4%), respectively. It was correctly understood in 273/300 (91.0%). The majority (275/300; 91.6%) correctly performed the HIV self-test; however, 71/300 (23.0%) asked for oral assistance. Most of the participants (273/300; 91.0%) found that performing of the self-test was very easy or easy, and less than Most of participants (273/300; 91.0%) found that performing of the self-test was very easy or easy and less than 1.0% (2/300) found it difficult. Overall the result were correctly interpreted in 96.9% (3,782/3,900), the reading/interpretion errors concerned the positive (96/1,800;5.3%), invalid (17/600;2.8%) and negative (5/1,500; 0.3%) self-test. The Cohen's coefficient κwas 0.94. The main obstacle for HIVST was the educational level, with interpretation difficulties in poorly educated people. Conclusions: Our observations on profane adults living in Central African Republic, demonstrate: (i) the need to adapt the notice of instruction to African public, including educational pictograms as well as notice in vernacular language(s); (ii) the frequent difficulties in understanding the notice with frequent misinterpretation of test results; (iii) and the generally good usability of the HIV self-test despite these latter pitfalls. More research on exploring the best strategy (i.e. supervised versus unsupervised strategies) for different high- and low- risk populations in resource-constrained settings remains needed.

Abstract
Objective The aims of the study were i) to categorize female sex workers (FSW) according to socio-anthropologic criteria in Bangui; ii) to examine the association between a selection of demographic and risk variables with the different categories of female sex work as outcome, and iii) to investigate factors associated with HIV status. Methods A cross-sectional questionnaire survey was conducted to describe the spectrum of commercial sex work in Bangui among 345 sexually active women. After collection of social and behavioral characteristics, each woman received a physical examination and a blood sample was taken for biological analyses, including HIV testing. The relationships between sociodemographic characteristics, behavioral variables involved in high risk for HIV as well as biological results were investigated by bivariate analysis in relationship with FSW categories as main outcomes, and by bivariate analysis followed by multivariate logistic regression analysis in relationship with HIV as the main outcome. The strength of statistical associations was measured by crude and adjusted Odds ratios (OR) and their 95% confidence intervals. Results The typology of FSW comprised six different categories. Two groups were the “official” professional FSW primarily classified according to their locations of work [i) “kata“(18.55%) representing women working in poor neighborhoods of Bangui; ii) “pupulenge” (13.91%) working in hotels and night clubs to seek white men]. Four groups were “clandestine” nonprofessional FSW classified according to their reported main activity [i) “market and street vendors” (20.86%); ii) “schoolgirls or students” (19.13%) involved in occasional transactional sex (during holidays); iii) “housewives or unemployed women” (15.65%); iv) “civil servants” (11.88%) working as soldiers or in the public sector]. The overall prevalence of HIV-1 was 19.12% (66/345). HIV varied according to FSW categories. Thus, among professional FSW, the HIV prevalence was 6-fold higher in "kata" than "pupulenge" (39.13% versus 6.30%; P = 0.001). Among nonprofessional FSW, the "vendors" showed the highest HIV prevalence (31.91%), which was higher than in "students" (6.10%; P = 0.001), "civil servants" (9.83%; P = 0.005), and "housewives" (13.00%; P = 0.01). In bivariate analysis, the following variables showed statistically significant association with risk for HIV infection: nationality; age of first sexual intercourse; self-assessment of HIV risk; knowledge of HIV status; anal sex practice with last clients; irregular condom use in last week; consumption of alcohol; other psycho-active substances; past history of STIs; HBs Ag; HSV-2 and bacterial vaginosis. However, the variable “sex workers categories” dichotomized into professional versus nonprofessional FSW was no longer associated with HIV. In multivariate logistical regression analysis, HIV infection was strongly associated with nationality (15.65% versus 3.77%) [adjusted OR (aOR) 3.39: 95% CI:1.25–9.16, P<0.05]; age of first sexual intercourse (21.10% versus 14.00%) (aOR 2.13: 95% CI: 1.03–4.39, P<0.05); anal sex practice with last clients (43.40% versus 11.50%) (aOR 4.31: 95% CI:2.28–8.33, P<0.001); irregular condom use in past week (33.50% versus 3.00%) (aOR 5.49: 95% CI:1.89–15.98, P<0.001); alcohol consumption before sex (34.70% versus 7.80%) (aOR 2.69: 95% CI:1.22–4.96, P<0.05); past history of STIs (41.00% versus 10.80%) (aOR 2.46: 95% CI:1.22–4.97, P<0.05) and bacterial vaginosis (29.80% versus 4.29%) (aOR 6.36: 95% CI: 2.30–17.72, P<0.001). Conclusion Our observations highlight the high level of vulnerability for HIV acquisition of both poor professional “kata” and nonprofessional “street vendor” FSW categories. These categories should be particularly taken into account when designing specific prevention programs for STIs/HIV control purposes.

Abstract
HIV testing and counselling is the first crucial step for linkage to HIV treatment and prevention. However, despite high HIV burden in sub-Saharan Africa, testing coverage is low, particularly among young adults and men. Community-based HIV testing and counselling (testing outside of health facilities) has the potential to reduce coverage gaps, but the relative impact of different modalities is not well assessed. We conducted a systematic review of HIV testing modalities, characterizing community (home, mobile, index, key populations, campaign, workplace and self-testing) and facility approaches by population reached, HIV positivity, CD4 count at diagnosis and linkage. Of 2,520 abstracts screened, 126 met eligibility criteria. Community HIV testing and counselling had high coverage and uptake and identified HIV-positive people at higher CD4 counts than facility testing. Mobile HIV testing reached the highest proportion of men of all modalities examined (50%, 95% confidence interval (CI) = 47-54%) and home with self-testing reached the highest proportion of young adults (66%, 95% CI = 65-67%). Few studies evaluated HIV testing for key populations (commercial sex workers and men who have sex with men), but these interventions yielded high HIV positivity (38%, 95% CI = 19-62%) combined with the highest proportion of first-time testers (78%, 95% CI = 63-88%), indicating service gaps. Community testing with facilitated linkage (for example, counsellor follow-up to support linkage) achieved high linkage to care (95%, 95% CI = 87-98%) and antiretroviral initiation (75%, 95% CI = 68-82%). Expanding home and mobile testing, self-testing and outreach to key populations with facilitated linkage can increase the proportion of men, young adults and high-risk individuals linked to HIV treatment and prevention, and decrease HIV burden.

Abstract
Among 464 sera from adults in Cameroon, 56 (12.1%) gave inconclusive HIV serology. All were negative for HIV-1 DNA; 44.6% (n = 25) were significantly associated with Plasmodium (42.8%) or Epstein-Barr virus (EBV) (17.8%) infections. In Central Africa, sera giving inconclusive results for HIV are frequently associated with malaria, EBV infection, or both.

Abstract
Separated, divorced, and widowed individuals in Africa are at significantly increased risk for HIV infection. Using nationally representative data from 13 sub-Saharan African countries, this study confirms that finding and goes further by examining those who have experienced a marital dissolution and are now remarried. Results show that remarried individuals form a large portion of the population and have a higher-than-average HIV prevalence. HIV-positive remarried individuals are at risk of transmitting the infection to their spouse, because many of the couples are serodiscordant. The large number of high-risk remarried individuals is a source of vulnerability and further infection, and should be acknowledged and taken into account by prevention strategies that rarely address this population.

Abstract
Linkage to HIV care and survival in sub-Saharan Africa is not well documented. In 2004 we conducted a randomized trial among medical inpatients in Mulago Hospital to assess the impact of HIV counseling and testing (HCT) on linkage to care and survival. Participants were randomized to inpatient HCT (intervention) or outpatient HCT 1 week post-discharge (control); inpatient HCT was not available at Mulago during the study. Among 590 eligible patients, 85% (500) agreed to participate; 98.8% (248) in the intervention arm received HCT compared to 68.7% (171) in the control arm. Within 6 months, 62.2% (92) of surviving HIV-infected participants received HIV care; 15.0% (20) received antiretroviral medications (ARVs). Overall mortality among HIV-infected participants was 34.6% (72). HCT had significant impact on linkage to care among surviving participants. Referral for HCT was a missed opportunity for diagnosis. There is need for earlier diagnosis and linkage to HIV care among inpatients.

Abstract
BACKGROUND Most couples affected by HIV/AIDS in sub-Saharan Africa live in discordant relationships. Men are thought to be the index case in most relationships, and most social marketing and awareness campaigns are focused on men. We investigated serodiscordance in stable relationships to establish the gender balance of index-case infections. METHODS We did a systematic review, random-effects meta-analysis, and meta-regression of published and unpublished studies enrolling discordant couples and assessed the proportion of men and women that were index cases. We repeated the analysis with data from demographic and health surveys (DHS) from the 14 countries that have documented the HIV status of couples. Our primary outcome was the total number of HIV discordant couples, including the proportion of HIV-positive women. FINDINGS We included data from 27 cohorts of 13,061 couples and DHS data from 14 countries of 1145 couples. The proportion of HIV-positive women in stable heterosexual serodiscordant relationships was 47% (95% CI 43-52), which shows that women are as likely as men to be the index partner in a discordant couple. DHS data (46%, 41-51) and our sensitivity analysis (47%, 43-52) showed similar findings. Meta-regression showed that urban versus rural residence (odds ratio 0.31, 95% CI 0.22-0.39), latitude (β coefficient 0.02, 0.023-0.034), gender equality (β coefficient -0.42, -0.56 to -0.27), HIV prevalence (β coefficient -0.037, -0.04 to -0.030), and older age (β coefficient 0.20, 0.08-0.32) were associated with the proportion of female index cases. INTERPRETATION Our study shows the need to focus on both sexes in HIV prevention strategies, such as promotion of condom use and mitigation of risk behaviours. FUNDING None.

Abstract
We explored the utility of routine HIV testing data from clinical services for estimating HIV prevalence. A systematic review identified 28 eligible publications, covering concentrated epidemics (16 of 28) and generalized epidemics (12). Of the 16 papers from concentrated epidemics, five presented estimates by risk group and four by testing history with a median HIV prevalence of 1.8% in first-time testers compared with 3% in repeat testers. Two reports from generalized epidemics restricted estimates to asymptomatic clients and three included breakdowns by reason-for-test, with the median HIV prevalence higher in symptomatic clients (62%) than others (24%). Two papers from generalized epidemics showed prevalence estimates based on routine HIV testing data were slightly higher than estimates derived from other surveillance methods, but did not restrict estimates to asymptomatic patients. We conclude that routine HIV testing data may be a supplementary data source for HIV surveillance provided careful analyses are conducted.

Abstract
The objective of this study was to assess the impact of temporary closure of an HIV research clinic on the health of study participants. Primary data were collected quarterly from couples enrolled in research studies at an established HIV study site. There were 632 participating couples enrolled when the project closed, 475 of whom returned when it re-opened six months later. HIV sero-incidence, mortality rates and risk-taking behaviours were compared before and during the closure. Perceived impact of the closure was measured in returning participants. Demographic data collected at the last pre-closure study visit were used to look at the differences between returning and non-returning study participants. Serologic data from those who returned were compared pre- and post-closure to examine changes in HIV incidence. Mortality rates were estimated from reported deaths, and were compared pre- and during project closure. Perceptions of the impact of the closure among returning participants were examined through an interviewer administered questionnaire. It was found that couples who returned were not demographically different from couples who did not return. Most participants reported no problems with finding alternate sources of condoms and the incidence of HIV did not change significantly during the closure. Eighty-four percent respondents reported that the closure had a negative impact on them, 87% of whom rated loss of medical care as the main impact. The mortality rate among HIV-positive participants doubled from 6.7/100 person years to 12.4/100 person years during the closure (p=0.01). Results indicate that couples voluntary counselling and testing (CVCT) established durable risk-reduction behaviours that persisted during project closure. ThIn ae loss of healthcare was perceived as the most negative impact on participants, reflected in increased mortality rates. Research projects should make transition plans and budget for mechanisms to reduce the negative impact on participants of project closures.

Abstract
OBJECTIVE Mulago and Mbarara hospitals are large tertiary hospitals in Uganda with a high HIV/AIDS burden. Until recently, HIV testing was available only upon request and payment. From November 2004, routine free HIV testing and counselling has been offered to improve testing coverage and the clinical management of patients. All patients in participating units who had not previously tested HIV-positive were offered HIV testing. Family members of patients seen at the hospitals were also offered testing. METHODS Data collected at the 25 participating wards and clinics between 1 November 2004 and 28 February 2006 were analysed to determine the uptake rate of testing and the HIV seroprevalence among patients and their family members. FINDINGS Of the 51,642 patients offered HIV testing, 50,649 (98%) accepted. In those who had not previously tested HIV-positive, the overall HIV prevalence was 25%, with 81% being tested for the first time. The highest prevalence was found in medical inpatients (35%) and the lowest, in surgical inpatients (12%). The prevalence of HIV was 28% in the 39,037 patients who had never been tested before and 9% in those who had previously tested negative. Of the 10,439 family members offered testing, 9720 (93%) accepted. The prevalence in family members was 20%. Among 1213 couples tested, 224 (19%) had a discordant HIV status. CONCLUSION In two large Ugandan hospitals, routine HIV testing and counselling was highly acceptable and identified many previously undiagnosed HIV infections and HIV-discordant partnerships among patients and their family members.

Abstract
Although the documented incidence and prevalence of HIV/AIDS in South Korea are relatively low in comparison with other counties, rates are steadily rising. It is believed that many cases have not been diagnosed because of the extreme stigma associated with HIV/AIDS in South Korea that serves as a barrier to voluntary counseling and testing (VCT). Little is currently known about individuals who present for counseling and testing. The purpose of this study was to explore the characteristics of individuals who sought VCT at the Korean Alliance to Defeat AIDS (KADA). Data were collected from 264 individuals who presented for VCT between October 1 and December 30, 2005, using self-administered questionnaires. More men than women (218 and 46, respectively) participated in this study. A large majority (85.3%) reported never using condoms and/or inconsistent condom use. The major reasons given for seeking HIV testing were unprotected sexual intercourse with commercial sex workers, premarital sex, and extramarital sex. Although none of the participants were HIV-positive, most were engaged in high risk sexual behaviors. Additionally, participants sought HIV testing at KADA because the results were rapidly available and their anonymity was ensured. The results suggest the need for interventions focused on safer sex practices and the importance of rapid HIV testing and assurance of anonymity to those in need of testing.

Abstract
This study investigated the efficacy of voluntary counseling and testing (VCT) in an educated cohort of pregnant women attending antenatal clinics in Urumqi, China. VCT was given to women and their partners (experimental group) or women alone (control group). Both groups were given pre- and post-intervention questionnaires to assess HIV knowledge and willingness to get HIV testing. Multivariate analysis showed that all women improved significantly in HIV knowledge between baseline and follow-up. Moreover, HIV knowledge was significantly associated with HIV testing willingness. At follow-up, women in the control and experimental groups were 6.8 and 7.9 times more willing to receive HIV testing than at baseline, respectively. VCT seems effective in this cohort of educated pregnant women.

Abstract
While the majority of medical inpatients in Uganda are assumed to be HIV-positive, HIV testing is limited in inpatient settings. This study describes HIV testing practices and risk behavior among medical inpatients at an urban hospital in Uganda. We interviewed 395 adults on the day of discharge. Overall, 46% tested for HIV before or during admission. Of the 20% tested during hospitalization, 64% were HIV-positive. Among 47% who had sex in the previous year, only 14% used condoms consistently and only 20% knew the HIV status of their sexual partner, indicating that participants would benefit from risk-reduction counseling. Yet, only 26% of participants tested during hospitalization received post-test counseling. Half of the participants with HIV-related illnesses left the hospital without being offered the test, a missed opportunity for HIV prevention counseling and care. The findings indicate that hospitals are important venues for HIV counseling and testing.

Abstract
OBJECTIVE To evaluate the efficacy of voluntary counselling and testing (VCT) for HIV/AIDS in changing risky sexual behaviour in central Mozambique. METHOD Longitudinal cohort study of men and women aged at least 18 years from October 2002 to June 2003. We interviewed 622 participants in VCT groups and 598 in non-VCT groups. The interviews occurred before counselling and 4 and 6 months afterwards. RESULTS Reported use of condoms while having sex with a friends/prostitute increased over each time period in the VCT group and between baseline and first visit in the non-VCT group. Both men and women in the VCT group increased their condom use over time, but the women in the non-VCT group did not. Reported always/sometimes use of condoms for both literate and illiterate subjects was higher and rose over time in the VCT group. CONCLUSION People who undergo voluntary counselling and testing fro HIV/AIDS change their behaviour, presumably as a result of their counselling.

Abstract
Voluntary counseling and testing (VCT) services have become an integral component of HIV prevention efforts in sub-Saharan Africa. This study of a rural Malawi district population examined variation in past and desired use of VCT services among 868 women aged 15 to 34 and 648 men aged 20 to 44 aware of HIV/AIDS. Only 11% of men and 7% of women had been tested, but of those untested, 76% of men and 61% of women desired testing. Ninety percent of respondents willing to know their results preferred to hear them from a test site counselor and on the same day of the test. However, 27% of women wanting to be tested did not want to know their test results, a finding significantly associated with knowing someone affected by AIDS and perceiving oneself at HIV infection risk. Knowledge of the behaviors of HIV prevention, knowing someone with AIDS, knowing the locations of a test site, and perceived risk of HIV infection all had a consistently significant association with past and future VCT use for men and women.

Abstract
OBJECTIVES We evaluated the cost-effectiveness of fee-based and free testing strategies at an HIV voluntary counseling and testing (VCT) program integrated into a community-based AIDS service organization in Moshi, Tanzania. METHODS We waived the usual fee schedule during a 2-week free, advertised VCT campaign; analyzed the number of clients testing per day during prefree, free, and postfree testing periods; and estimated the cost-effectiveness of limited and sustained free testing strategies. RESULTS The number of clients testing per day increased from 4.1 during the prefree testing interval to 15.0 during the free testing campaign (P<.0001) and remained significantly increased at 7.1 (P<.0001) after resumption of the standard fees. HIV seroprevalence (16.7%) and risk behaviors were unchanged over these intervals. Modeled over 1 year, the costs per infection averted with the standard fee schedule, with a 2-week free VCT campaign, and with sustained free VCT year-round were $170, $105, and $92, respectively, and the costs per disability-adjusted life year gained were $8.72, $5.40, and $4.72, respectively. CONCLUSIONS The provision of free VCT enhances both the number of clients testing per day and its cost-effectiveness in resource-limited settings.

Abstract
OBJECTIVE To determine whether data from voluntary counseling and testing (VCT)/prevention of mother-to-child transmission (PMTCT) programs can be used for HIV surveillance. METHODS Women attending an antenatal clinic at the district hospital in Entebbe, Uganda, from May 2002 to April 2003 were offered counseling and HIV testing with same-day results (VCT) and nevirapine for PMTCT was provided for HIV-positive women and their babies. Those who declined VCT were tested for HIV anonymously. RESULTS Overall, 2635 women accepted VCT; 883 were tested anonymously. HIV prevalence was higher in VCT than in anonymously tested women in the first month of the program (20% vs. 11%, P=0.05) and in months with <70% VCT uptake (17% vs. 8%, P<0.001) but was similar in months with high uptake. Uptake of VCT was higher in women who had risk factors for HIV, especially those who believed themselves to have been exposed (84% vs. 73%, P<0.001). CONCLUSION There was a bias to accepting VCT in women with HIV, or risk factors for HIV infection, the former most apparent when there was low coverage. Data from VCT/PMTCT programs cannot replace anonymous surveillance for monitoring of HIV epidemic trends where coverage is incomplete within clinics or communities.
