Hepatitis B and C: Seroprevalence, knowledge, practice and associated factors among medicine and health science students in Northeast Ethiopia

Hepatitis B screening and knowledge among Chinese and Vietnamese students in Australia

Research has shown that there are significant gaps in hepatitis B knowledge among migrant communities who are at risk of hepatitis B, such as Chinese and Vietnamese communities. Many students studying within Australia come from countries with high prevalence of hepatitis B. However, there is very little research examining hepatitis B knowledge, screening, or vaccination among university students in Australia or worldwide. The aim of this paper was to measure both levels of and demographic differences in hepatitis B screening and knowledge among Chinese and Vietnamese students in Australia. Online surveys were completed by 112 Chinese- and 95 Vietnamese-identifying students in Australia, measuring knowledge of hepatitis B, engagement in screening and vaccination, and demographic characteristics. Results show that although engagement in screening and vaccination for hepatitis B was high, there were significant gaps in knowledge around transmission of hepatitis B. There were also some key demographic differences in screening and knowledge. For instance, those born in Australia were more likely to have been screened compared to those born Mainland China, Hong Kong, or Vietnam. Chinese students born in Australia had lower levels of knowledge compared to those born in Mainland China or Hong Kong. Among both samples, knowing someone living with hepatitis B was associated with higher levels of knowledge. Findings underscore the need for education-based interventions to address the significant gaps that exist in knowledge around hepatitis B, with a specific need for culturally appropriate resources in a range of languages to cater to the diverse communities who may be at risk of hepatitis B.

Knowledge, attitude and practice towards Hepatitis B vaccination among medical undergraduate students of Maharajgunj Medical Campus in Nepal: a cross-sectional study

Background

The rate of Hepatitis B virus (HBV) infection among health professionals is about 2-10 times higher than that of the general population since, they are more prone for exposure to infected blood and body fluid and contaminated needles and syringes. The risk of accidental exposure among the medical students is even higher due to their non-experience, insufficient training and lack of preventive knowledge. The objective of this study is to assess knowledge, attitude, and practice of medical students towards Hepatitis B.

Methods

A cross-sectional study design was conducted among 206 medical undergraduate students from May 2022 to July 2022. A pretested self- administered questionnaire was used to collect data regarding knowledge, attitude, and practice towards Hepatitis B vaccination. Non-probability convenience sampling was used to collect data. Descriptive analysis was done by calculating frequency and percentages of categorical variables. χ2 test was used to determine the association between categorical independent variables and categorical dependent variables.

Results

Among 206 students, 93.7% of them had good knowledge and 98.5% had good attitude. The practice was low with only 35% having safe practices. Similarly, only 46.6% of medical students were completely vaccinated. 23.8% had done Hepatitis B testing. Students who had encountered Hepatitis B patients during their posting were 51.9%. There was significant association of sociodemographic variables with knowledge, attitude and practice towards Hepatitis B vaccination.

Conclusion

Although, the knowledge and attitude towards Hepatitis B vaccination is high, the practice levels are very low. This indicates need for immunizing medical students against Hepatitis B and reforming training curriculum more focusing on preventive practices against HBV.

Sharps injuries within the healthcare student population: a narrative review

BACKGROUND

Studies have reported evidence on sharps injuries among nursing, medical and dental students but little is known about the amount, type and causes of sharps injuries affecting other healthcare students.

AIM

The aim of the narrative review was to identify the extent, type and causes of sharps injuries sustained by healthcare students, especially those not in those fields.

METHOD

Eight databases were searched using keywords to identify studies published between 1980 and March 2023.

FINDINGS

This narrative review highlights that some groups of healthcare students, including those studying pharmacy, physiotherapy and radiography, sustain sharps injuries from similar devices as reported in research on such injuries in nursing, medical and nursing students. Sharps injuries happen in a range of healthcare environments, and many were not reported by students. The main cause of a sharps injury identified was a lack of knowledge.

CONCLUSION

More research is needed on the extent of sharps injuries in healthcare students in European countries and the UK as well as on their physical and psychological effects. Education and training in sharps use and disposal are essential.

Hepatitis B virus immunity prior to and after administration of a ‘booster’ dose of vaccine among health-care students at a South African university

Background

Health-care students (HCSs) are at risk of occupational exposure to hepatitis B virus (HBV) infection despite an effective hepatitis B vaccine (HepB) being available. The majority of current HCSs are born after HepB was introduced into the South African Expanded Programme on Immunisation in 1995. Thus, it is assumed that having received HepB in infancy, a single 'booster' dose would suffice. This study aimed to investigate HBV immunity prior to and after administration of a HepB 'booster' dose.

Methods

Hepatitis B surface antibody (anti-HBs) levels were determined in first year HCSs at the University of the Witwatersrand, before and after receiving the 'booster'. Participant demographics and HepB history were captured using a structured questionnaire.

Results

Before receiving the 'booster', 56% (101/180) had anti-HBs < 10 mIU/mL and were non-immune. A further 35% had anti-HBs levels of 10 - 99 mIU/mL, and 9% had ≥100 mIU/mL. <30% of HCSs self-reported completion of a three-dose primary series, which was significantly associated with higher baseline anti-HBs levels compared to those with a partial schedule (p = 0.045). Following vaccination, 39% (71/180) returned for follow-up with a significant median (IQR) increase of 476 (151 - 966) mIU/mL (p < 0.001). Of the 45 students who had non-immune baseline levels, 73% (33/45) responded with ≥100 mIU/mL, 16% (7/45) with 10 - 99 mIU/mL and 11% (5/45) remained non-immune. Levels of ≥100 mIU/mL were achieved by 100% of students with baseline levels ≥10 mIU/mL (n = 26).

Conclusion

More than half of the HCSs were not immune to HBV prior to receiving the recommended 'booster' vaccine. Following vaccination, 7% (5/71) remained unprotected. This study highlights that in the absence of vaccination records and without confirming the immune status of HCSs, it cannot be assumed that HCSs will be protected following a 'booster'. Policy reform and inclusion of serological tests for immunity prior to HCSs initiating clinical exposure are recommended.

Prevalence of hepatitis B virus and immunity status among healthcare workers in Beira City, Mozambique

BACKGROUND

Hepatitis B virus (HBV) infection can be prevented by vaccination. Exposure to blood or body fluids poses a high risk of transmission of HBV in health care workers (HCWs). This study aimed to determine the prevalence of markers of exposure, susceptibility, and protection to HBV infection in HCWs in Beira, Mozambique.

METHODS

A cross-sectional study was conducted between June and August 2020 in Beira City, Mozambique, in HCWs based on self-administered questionnaires and blood samples. Plasma samples were tested for HBV surface antigen (HBsAg), antibodies to HBV core antigen (anti-HBc), antibodies to HBsAg (anti-HBs) and HBV viral load (HBV DNA).

RESULTS

Most of the 315 HCWs in the study were nurses (125; 39.7%). Of the HCWs, 5.1% (16; 95% Confidence Interval (CI): 2.9 to 8.1%) were infected by HBV (HBsAg and/or HBV DNA positive). Occult HBV infection (OBI) (HBV DNA positive and HBsAg negative) was found in 0.3% (1; 95% CI: 0.0 to 1.8%) of participants; 27.9% (88; 95% CI: 23.1 to 33.2%) were susceptible (negative for all markers), 6.3% (20; 95% CI: 3.9 to 9.6) were immune due to natural infection (anti-HBs and anti-HBc positive only), while 60% (189; 95% CI: 54.4 to 65.5) were immune due to vaccination (anti-HBs positive only).

CONCLUSION

This study showed a high intermediate prevalence of chronic hepatitis B among healthcare workers in Beira City, Central Mozambique, and one-third of healthcare workers were susceptible to HBV infection. There is a need to implement a national hepatitis B screening and vaccination strategy among healthcare workers in Mozambique.

Practice towards Hepatitis B Virus Infection Prevention and Its Associated Factors among Undergraduate Students at Hawassa University College of Medicine and Health Sciences, Hawassa, Sidama, Ethiopia, 2021: Cross-Sectional Study

BACKGROUND

Hepatitis B virus infection is a major global health burden accounting for 2.7% of all deaths globally. Being part of the health care system, the risk of exposure to hepatitis B viral infection among medical and health science students is found to be high. In Ethiopia, particularly in this study area, very little is known about the practice of students towards hepatitis B virus infection prevention and its associated factors.

OBJECTIVE

The aim of this study was to assess the practice towards hepatitis B virus infection prevention and its associated factors among undergraduate students at Hawassa University College of Medicine and Health Sciences, Hawassa, Ethiopia, 2021.

METHODS AND MATERIALS

An institution-based cross-sectional study was conducted from May 15 to June 15, 2021, among undergraduate students who had clinical exposure. The 404 sampled participants were recruited using a systematic random sampling technique. Data was collected using a structured self-administered questionnaire. Data was entered into EpiData version 4.6.0 and was exported to SPSS version 25 for analysis. Association between the dependent and independent variables was computed using the bivariate and multivariate logistic regression model. Odds ratio was calculated. Results were interpreted as significant if P value is <0.05 at 95% CI.

RESULT

This study revealed that 277 (69.9%) of the students were in the age group of 20-24 years and 266 (67.2%) were males. Out of 396 participants, about half 199 (50.3%) 95% CI (0.452-553) had a good practice towards hepatitis B virus infection prevention. Only 43.4% of the study participants had been completely vaccinated against hepatitis B virus. Age (20-24 years) (AOR = 2.736), 95% CI (1.130-6.625), and good knowledge (AOR = 1.990), 95% CI (1.207-3.282) were factors significantly associated with the practice towards hepatitis B virus infection prevention. Conclusion and Recommendation. The current study showed that about half of the study participants had good practice towards hepatitis B virus infection prevention but more than half were not completely vaccinated against HBV. Age and knowledge were factors significantly associated. It is recommended to give training for students on hepatitis B virus infection prevention. It is also advisable to screen and vaccinate students before they start their clinical attachments.

Frequency of Hepatitis B, C, and Human Immunodeficiency Virus in Blood Donors

Introduction: Blood donation is considered an important source of infection transmitted through transfusion, especially in developing countries like Pakistan.

Objective: To find out the frequency of seroprevalence of hepatitis B virus (HBV), hepatitis C virus (HCV), and human immunodeficiency virus (HIV) among blood donors in the blood bank.

Methods: A prospective cohort study was carried out on blood donors at the National Institute of Blood Disease and Bone Marrow Transplant, Karachi, during the period of January 1, 2019 to December 31, 2020. The descriptive statistical analysis to find out the percentages and frequencies was implemented using SPSS version 23 (IBM Corp., Armonk, NY).

Results: During the study duration, a total of 23,656 blood donors visited and donated blood, including 12,234 blood donors in the year 2019 and 11,422 blood donors in the year 2020. According to the analysis, only 1.4% of patients with HBV, 1.5% with HCV, and 0.03% were seropositive in the year 2020. In 2019, 1.6% HBV, 2.07% HCV, and 0.09% HIV blood donors were seropositive with a significant 0.00 p-value.

Conclusion: It is concluded that hepatitis C is the most commonly occurring in donors compared to HBV and HIV. HBV vaccines are available in Pakistan, which is why cases are fewer than HCV.

Sero-Prevalence of HBV and its Associated Factors Among Healthcare Providers in Public Health Facilities in Eastern Ethiopia

Background:

Healthcare providers are in high occupational risk of Hepatitis B virus infection than that of the general population because of the high risk of occupational exposure to patients’ body fluids and accidental sharp injuries. There are no large facility-based studies conducted on the prevalence of HBV infection and its associated factors among health care providers in eastern Ethiopia.

Objective:

This study aimed at investigating the seroprevalence of Hepatitis B Virus and its associated factors among the healthcare providers in public health facilities in eastern Ethiopia.

Methods:

A facility-based cross-sectional study was conducted among 438 randomly selected healthcare providers in eastern Ethiopia from March to June 2018. Pretested structured questionnaire was used to collect data on socio-demographic characteristics and other risk factors. In addition, a 2.5 ml blood was collected and the serum was analyzed for Hepatitis B surface antigen using the Instant Hepatitis B surface antigen kit. Data were entered using Epidata version 3.1 and analyzed using SPSS statistical packages version 22. Descriptive summary measures were used. Bivariate and multivariable logistic regression was conducted at 95% CI. An association at P-value <.05 was considered statistically significant.

Results:

A total of 438 (92.02% response rate) health care providers have participated in this study. The prevalence of hepatitis B virus infection was 9.6%. There were no significant differences in the HBV infection rates among healthcare providers with respect to socio-demographic characteristics (P-value >.05). After adjusting for some variables, the following variables remained statistically significantly associated with HBsAg positive result in the multivariable analysis: exposure to body fluids (AOR = 3.0; 95% CI [1.25, 7.05]), history of needle stick injury (AOR = 4.70; 95% CI [2.10, 10.55]), history of operation/surgery (AOR = 4.88, 95% CI [1.43, 16.62]), history of multiple sexual partner (AOR = 7.48; 95% CI [2.08, 26.96]), and being unvaccinated (AOR = 6.09; 95% CI [2.75, 13.51]).

Conclusion:

This study showed a high prevalence of HBV infection among health care providers in eastern Ethiopia. This is significant because health professionals may be at increased risk of chronic complications and may also be source of infection for their clients and general population during their healthcare practice. Management commitment that should focus on occupational safety and health promotions is necessary.

Healthcare students' vaccination status, knowledge, and protective behaviors regarding hepatitis B: a cross-sectional study in Turkey

AIM

We aimed to determine the vaccination status, knowledge, and protective behaviors of healthcare students related to hepatitis B and to examine the related factors.

METHOD

This cross-sectional study was conducted in seven universities from seven geographical regions of Turkey. The study group included 5451 healthcare students. Data were collected with a questionnaire including items on sociodemographic characteristics, vaccination status, knowledge and protective behaviors related to hepatitis B. Data were analyzed with Pearson's chi-square and logistic regression analyses.

RESULTS

86.0% of the students had hepatitis B vaccine while 7.6% did not. Vaccination was higher in nursing and midwifery students (aOR = 1.87, CI 95%: 1.26-2.77; aOR = 3.87, CI 95%: 2.14-7.02, respectively). Vaccination was 1.28 times higher in females (CI 95% 1.03-1.60). The ≥23 age group had 1.79 times higher vaccination rate than those in the ≤19 (CI 95%: 1.26-2.53). Vaccination was higher in students whose family's economic status is middle and high (aOR = 1.53, CI 95%: 1.07-2.19; aOR = 1.47, CI 95%: 1.03-2.19, respectively). Vaccination was higher in those living in towns and cities during childhood (aOR = 1.36, CI 95%: 1.06-1.74; aOR = 1.79, CI 95%: 1.34-2.38, respectively). Females had more knowledge of hepatitis B and protective behaviors. Both knowledge and protective behavior scores of vaccinated participants were significantly higher (p < .05).

CONCLUSION

We found that the vaccination rate in healthcare students was high, but lower than the country's targets. The students were sensitive about the protective behaviors from hepatitis B infection and had sufficient knowledge of HBV contamination.

Knowledge, Vaccination Status, and Reasons for Avoiding Vaccinations against Hepatitis B in Developing Countries: A Systematic Review

(1) Background: The coverage of hepatitis B vaccination remains low in developing countries to date. This systematic review thus analyzes the determinants of people’s knowledge and vaccination status as well as the reasons why people in developing countries chose not to receive the hepatitis B vaccination. (2) Methods: We searched four databases to identify all studies from developing countries published within the past 10 years. Both low-risk and high-risk populations aged older than 15 years old were eligible for the study. The quality of studies was assessed by the Newcastle–Ottawa Scale assessment. (3) Results: This study identified 2443 articles, 89 of which were included in the analysis. Monthly income, occupational status, and profession as a health-care worker were the strongest predictive factors for both knowledge of hepatitis B and vaccination status. In addition, strong predictor variables of hepatitis B knowledge were knowing an infected person and level of education, while health insurance, management’s protection at workplace, infection training, and experience of hepatitis B exposure were strong influencing factors for vaccine uptake. (4) Conclusions: Exposure to information, support from institutions, and financial support related to vaccination cost have a positive impact on the knowledge about hepatitis B infection and vaccination coverage.

Hepatitis B-C and human immunodeficiency virus: seroprevalence and associated factors among health students in Saudi Arabia

OBJECTIVES

To assess the seroprevalence of Hepatitis B (HBV), Hepatitis C (HCV), and Human Immunodeficiency Virus (HIV) among newly admitted health track students in a large university in the Eastern Province of Saudi Arabia, and determine the students' immunity against HBV, and bloodborne viral infection risk factors or practices among them.

METHODS

Information about the 1145 students, vaccination history, and exposure to bloodborne viral infections risk factors/practices were collected using a structured questionnaire during August 2020. The results of serological data were obtained from students' electronic files.

RESULTS

All students tested negative for HBV, HCV, and HIV infections. The seroprevalence of positivity against HBV was 25.8%, and the frequencies of students with protective levels of anti-HBV were inversely related to their age. The majority (70.8%) of students had 1 or 2 identifiable risk factors for bloodborne diseases, and the most frequent risk factor was history of dental intervention. Female students were more than four-times likely to be in the high-risk group for bloodborne infections than males (OR = 4.4; 95% CI: 3.3-5.9). Being from the Central Province of Saudi Arabia (OR = 1.9; 95% CI: 1.2-3.1) and having a mother's educational level of master or doctorate (OR = 3.0; 95% CI: 1.3-6.7) were found to be independent predictors of being in the high-risk group. On the other hand, having a family member in the healthcare field was found as a predictor of being in the low-risk group for bloodborne diseases (OR = 0.7; 95% CI: 0.5-0.9).

CONCLUSION

About three-fourth of students in this study were susceptible to HBV. Our findings stress the need to develop policies to raise awareness regarding bloodborne infectious diseases, in addition to expanding access to HBV vaccination for healthcare staff, especially in older ages.

Seroprevalence of Hepatitis C Viral Infection in Ethiopia: A Systematic Review and Meta-Analysis

Background

Hepatitis C virus is a highly genetically heterogenous bloodborne pathogen that is responsible for acute and chronic hepatitis. Globally, an estimated 71 million population is chronically infected with this virus from which 399,000 people die every year. Its prevalence is high in Ethiopia and varies from region to region, even among different studies within a region.

Methods

Electronic databases, including Science Direct, Medline, HINARI, African Journals Online, TRIP database, African Index Medicus, and Directory of Open Access Journals, searched from 2010 to 2020 and published articles were included. Due to evidence of considerable heterogeneity, the pooled prevalence of anti-HCV was analyzed using the random-effects model. The possible sources of heterogeneity were analyzed through subgroup analysis, sensitivity analysis, and meta-regression. Funnel plots and Egger's test statistics were used to determine the presence of publication bias.

Results

The analysis of 56 articles showed that the prevalence of anti-HCV in Ethiopia ranged from 0% to 22%. The pooled prevalence estimated was 2% (95% CI 2.0–3.0), and the meta-regression statistics indicated that the diagnostic method (p=0.037), study group (p=0.005), and level of bias (p=0.035) showed statistically significant association with the outcome variable. The sensitivity analysis claims no influence on the overall effect estimate while removing a single study from the analysis at a time. Egger's test statistics (p ≤ 0.001) declare the presence of publication bias that is handled using time and fill analysis.

Conclusions

The pooled prevalence of anti-HCV in Ethiopia was high. Predictor variables, including the diagnostic method, study group, and level of bias, showed a statistically significant relationship with the outcome variable. Strengthening the scope of existing prevention and control programs and implementing novel approaches, including screen-and-treat, could significantly help to tackle this critical public health issue. The study provides a current estimate which is valuable for policymakers and other responsible bodies.

Prevalence and risk factors of hepatitis B virus infection among medical laboratory science students in a Ghanaian tertiary institution

Purpose

This study aimed to determine the prevalence and risk factors of hepatitis B virus (HBV) infection among medical laboratory science students (MLSSs) in the University of Health and Allied Sciences (UHAS), Ghana.

Design/methodology/approach

A cross-sectional study design was employed to recruit a total of 178 students into the study. A self-administered questionnaire was used to gather relevant information on risk factors, and a hepatitis B diagnostic test kit was used to test for HBV infection. Descriptive, chi-square test, bivariate and multiple logistic regression statistical analysis were computed. Significance was observed at p < 0.05.

Findings

The prevalence of HBV infection among MLSSs was 6.7%. Torn gloves and splash of blood and body fluids contributed to 43.0% and 28.0% of all the risk factors of HBV infection, respectively. Also, 43.3% of students had received at least one dose of the hepatitis B vaccination. Sharp object-related injury and torn gloves increased the odds of HBV infection, while vaccination decreased the odds of HBV infection.

Originality/value

This study reveals the prevalence of HBV among MLSSs, who are recognized as being among the high-risk student populations aside from student nurses.

Hepatitis B virus infection and associated risk factors among medical students in eastern Ethiopia

BACKGROUND

Hepatitis B virus (HBV) is a highly contagious pathogen that has become a severe public health problem and a major cause of morbidity and mortality, particularly in developing countries. Medical students are at high occupational risk during their training. However, no facility-based studies were found among medical students in eastern Ethiopia. Thus, this study aimed to investigate the seroprevalence of Hepatitis B Virus and associated factors among medical students in eastern Ethiopia.

METHODS

A facility-based cross-sectional study was conducted among 407 randomly selected medical students from March to June 2018. A pretested and structured questionnaire was used to collect data on socio-demographic characteristics and other risk factors. A 5ml blood was collected, and the serum was analyzed for Hepatitis B surface antigen (HBsAg) using the Instant Hepatitis B surface antigen kit. Data were entered using Epidata version 3.1 and analyzed using SPSS statistical packages version 22. Outcome and explanatory variables were described using descriptive summary measures. Binary and multivariable logistic regression was conducted at 95% CI and an association at P-value < 0.05 was declared statistically significant.

RESULTS

The seroprevalence of hepatitis B virus surface antigen was 11.5% (95%CI = 8.6, 14.7). Poor knowledge of universal precaution guideline (AOR = 2.58; 95% CI = [1.35-4.93]), history of needle stick injury (AOR = 2.11; 95% CI = [1.07-4.18]) and never been vaccinated for HBV (AOR = 2.34; 95% CI = [1.17-4.69]) were found statistically significantly associated with HBsAg positivity after multivariate analysis.

CONCLUSION

Hepatitis B virus infection rate is high among health care trainees in eastern Ethiopia. Improvement at health care practice centers safety through training on universal precaution guidelines, and scaling up HBV vaccination is mandatory.

Screening and linkage to care for medical students with hepatitis B virus infection in Sierra Leone

Purpose

Hepatitis B virus (HBV) infection is considered a major public health concern for Sierra Leone. Although medical students are at increased occupational risk for HBV infection, little is known about the burden of HBV infection amongst medical students in Sierra Leone.

Methods

As part of a screening and vaccination campaign, a cross-sectional study on prevalence of HBV among medical students in Freetown was conducted in December 2019. Antigen point of care test was used for HBV screening and data on students' risk history and demographics were collected. Additionally, for students diagnosed positive with HBV, linkage to care and initial assessment data after diagnosis was collected from the HBV clinic they were linked to.

Results

One hundred and fifty-seven medical students (77.3%) from year three to six were screened for HBV infection. Almost all students (98.1%) had never been vaccinated against HBV and more than half (56.7%) reported a history of needle stick injuries. The prevalence of HBV infection (Hepatitis B surface antigen (HBsAg) positivity) was 10.2% (n = 16). Among HBsAg positive students, 75% (n = 12) were successfully enrolled at chronic HBV clinic within three months of diagnosis. Only one student had evidence of liver cirrhosis and was started on treatment with Tenofovir diproxil fumarate.

Conclusion

The prevalence of HBV infection is high among medical students in Sierra Leone. Despite the high prevalence, most of the students linked to care had no evidence of severe liver disease.

A Survey on Medical, Dental, and Pharmacy Students' Knowledge, Attitude, and Practice about Hepatitis B Infection in a Private Medical University of Malaysia

Objective:

The present study aimed to assess the knowledge, attitude, and practice (KAP) of 3^rd- and 4^th-year medical, dental, and pharmacy students about hepatitis B (HB) infection at a private medical university, Malaysia.

Methods:

A cross-sectional, questionnaire-based study was conducted among 482 medical, dental, and pharmacy students of 3^rd- and 4^th-year degree program of Asian Institute of Medicine, Science and Technology University to assess their KAP about HB infection using 34 prevalidated questions by convenient sampling method. A questionnaire was administered to the students, and their responses were measured at “yes” and “no” scale. Students' responses were entered in SPSS version 22, and quantitative analysis was performed using descriptive statistics and nonparametric tests at P < 0.05.

Findings:

The medical, dental, and pharmacy students had good knowledge and practice with positive attitude about HB infection. Mann–Whitney U-test determined a significant difference in knowledge (P < 0.001) and practice (P < 0.001) scores between medical and pharmacy, attitude (P < 0.001) scores between medical and dental, and attitude (P < 0.001) and practice (P < 0.001) scores between pharmacy and dental students. Students' age was correlated with their attitude, practice, and KAP scores and family income with their knowledge, attitude, practice, and KAP scores.

Conclusion:

Although students' knowledge and practice were good with positive attitude, all the students did not participate in health education program, screening, and vaccination of hepatitis B virus (HBV) infection which makes them more vulnerable to occupational HBV infection. Hence, it is recommended to organize a regular health education program for the students on screening and vaccination against HBV to prevent its infection.

Assessment of Knowledge and Practice on Hepatitis B Infection Prevention and Associated Factors among Health Science Students in Woldia University, Northeast Ethiopia

Background

Hepatitis B virus is a global problem, with 66% of all the world population living in areas where there are high levels of infection. HBV is the leading risk factor for HCC globally and accounts for at least 50% of cases of HCC. Medical and health science students, being part of the health-care system, are exposed to the infection as a risk as other health-care workers when they come in contact with patients and contaminated instruments.

Objective

The main aim of this study was to assess the knowledge and practice of hepatitis B virus infection prevention and its associated factors among health science students in Woldia University.

Methods

Institutional-based cross-sectional study was conducted from January 30 to May 30, 2019, among health science students of Woldia University who had previous clinical attachments. Two hundred students were selected by the systematic random sampling method. Association of dependent and independent variables was computed using a bivariable and multivariable logistic regression model. P<0.05 was considered as significantly associated.

Result

The study revealed that, out of 200 participants, 96 (48%) have poor knowledge, whereas 104 (52%) showed good knowledge about HBV. Regarding the practice of participants, 79 (39.5%) of the students have good practice to prevent HBV, whereas 121 (59.5%) had poor practice towards HBV infection prevention.

Conclusion

Based on the current study, greater than half of the students who participated in the study have good knowledge of hepatitis B infection prevention and most of the students have poor practice about infection prevention of hepatitis B virus.

Knowledge, attitude and prevalence of hepatitis B virus among healthcare workers: a cross-sectional, hospital-based study in Bamenda Health District, NWR, Cameroon

INTRODUCTION

Hepatitis B virus (HBV) is a bloodborne virus which can be transmitted via percutaneous and mucocutaneous exposure to infected body fluid. Healthcare workers (HCWs) who are continuously exposed to different body fluids are at an increased risk of contracting and transmitting this virus. It is thus important to evaluate the knowledge and attitude of HCWs towards HBV and the prevalence of HBV infection among them.

METHODS

This cross-sectional study was carried out between April and September 2017. Overall, 398 HCWs were recruited for this study. Knowledge on the route of HBV transmission and attitude towards HBV were evaluated using a well-structured questionnaire. Hepatitis B surface antigen (HBsAg) positivity was obtained using the Monolisa HBsAg ULTRA kit (Bio-Rad). Data were analysed using SPSS V.20.

RESULTS

Among the HCWs who participated in this study, 338 (84.9%) had heard of HBV, and 269 (67.6%) of them had adequate knowledge on the route of HBV transmission. Medical doctors were the most knowledgeable among biomedical workers and students (76.5%). The rate of stigma was highest among nurses (87, 38.8%). The prevalence of HBsAg positivity was high (42, 10.6%) given that there is an efficient and available vaccine. Overall, over 70% of HCWs invited to participate in this study responded.

CONCLUSION

Knowledge on the route of HBV transmission was fair, and the level of stigmatisation of HBV-infected patients and the prevalence of HBV infection were high in this study. A sensitisation campaign should be carried out to educate HCWs on HBV, thus reducing the level of stigma associated with HBV as well as the probability of contracting HBV as a nosocomial infection.

Possible Mode of Spread of Hepatitis B and Hepatitis C in Chronic Liver Disease Patients Presenting at CMH Lahore Medical College and Institute of Dentistry

Introduction

Chronic hepatitis B and C are the leading causes of chronic liver disease and a significant cause of mortality and morbidity worldwide. Hepatitis B is a preventable disease with vaccination, which is available worldwide. About 257 million people are affected worldwide with hepatitis B and around 71 million people with hepatitis C, and Pakistan is the second most prevalent country with hepatitis C. The possible mode of spread of hepatitis B and C in chronic liver disease patients presenting at CMH medical wards and dental clinics was evaluated. Among various types of hepatitis, A, B, and C are the most common. The course of disease followed by hepatitis A is short term, but when we talk about the common types, which are B and C, the disease is chronic and, moreover, the complications associated with these types are more severe too.

Materials and methods

The study was carried out at the medical wards and dental clinics of CMH Lahore Medical College. A total of 240 patients were evaluated for the possible mode of spread of hepatitis B and C. A detailed history regarding the use of needles, surgical procedures, including dental treatment, unsterilized razors for shaving (barbers'), blood transfusions, tattooing, and mode of delivery in females, was evaluated and data were interpreted.

Aims and objectives

To observe the mode of spread of hepatitis B and C among patients of CMH Lahore Medical College and Institute of Dentistry.

Results

The results of our study revealed that the most common mode of spread of disease in males was exposure to infected blades and instruments at barbers' shops. In females, blood transfusion and caesarian section, especially in rural areas, remained the most common possible cause of spread. A small number of patients was not aware of the possible mode of transmission, whereas a few others did not seek treatment for the disease.

Conclusion

From our study, we can conclude that a substantial number of patients with chronic liver disease have exposure to various risk factors. Exposure to the unsterilized equipment of barbers and improperly screened blood remains the main cause of the spread of hepatitis B and C in males whereas surgical procedures related to gynecological procedures and blood transfusions remain the second most common cause. Dental procedures in the hands of trained dental professionals/dentists carry less danger of transmitting the disease but carry an equally high incidence if quacks do the dental procedures.

Knowledge, Attitude and Behavior Levels of University Students About Hepatitis A, Hepatitis B and Hepatitis C

Aim: The aim of this study is to reveal the knowledge, attitude and behaviors of the university students about Hepatitis A, Hepatitis B and Hepatitis C. Methods: This study was done among 1048 students from different faculties of five different universities in Ankara, was carried out between October 2012 and July 2013. A questionnaire was prepared by the authors by rewieving the literature and the participants were asked to fill this questionnaire. Knowledge level of participants was scored from 1 to 5 out of 100 according to the answers given about Hepatitis A, B and C. Results: When the average points of knowledge about hepatitis A, B and C is considered, it is seen that the knowledge points of males according to females and the knowledge points of the students who study in medical faculties according to the other faculties are higher. Participants were found to have a risky attitude with respect to the spread of Hepatitis A, B and C infections. While males had more risky behaviors, it was seen that there was no significant difference between the students of medical faculties according to other faculties. Conclusion: Despite advances in technology and health, Hepatitis A, B and C infections continue to be an important public health problem today. This study showed that even university students, whose education and intellectual levels are considered to be high according to society, have low level of knowledge about viral hepatitis and exhibit risky attitudes and behaviors, necessity of individual and social education. The most effective way to protect against these diseases is to increase the knowledge and awareness levels of the society and prevent the transmission of these diseases.

A Path to Ending Hepatitis C in Ethiopia: A Phased Public Health Approach to Achieve Micro-Elimination

Ethiopia's hepatitis C virus (HCV) prevalence is predicted to rise by 2030. To halt this increasing trend, a suitable approach to the elimination of HCV is needed. This review explores the current status, challenges, and opportunities and outlines a strategy for the micro-elimination approach in Ethiopia. I searched PubMed and EMBASE using combined Medical Subject Heading databases for the literature on HCV micro-elimination. A phased public health approach to HCV micro-elimination, including preparation/capacity building (phase I), implementation (phase II), and rollout and scale-up (phase III), targeting people living with HIV, prisoners, chronic hepatitis and cancer patients, blood donors, and pregnant women is a pragmatic strategy to Ethiopia. This can be implemented at general and tertiary care referral hospitals with a future scale-up to district hospitals through task-shifting by training general practitioners, nurses, laboratory technologists, and pharmacists. Availability of the highly effective direct-acting antivirals (DAAs) can be ensured by expanding the existing program that provides highly subsidized DAAs through an agreement with Gilead Sciences, Inc. and eventually aiming at domestic generic manufacturing. The significant enablers to HCV micro-elimination in Ethiopia include the control of healthcare-associated HCV infection, blood safety, access to affordable testing and pan-genotypic DAAs, task-shifting, multisectoral partnership, and regulatory support. General population-based HCV screening and treatment are not cost-effective for Ethiopia because of high cost, program complexity, and disease epidemiology.

An updated systematic review and meta-analysis of the prevalence of hepatitis B virus in Ethiopia

Background

Hepatitis B virus is one of the major public health concerns globally. It is highly infectious and can be transmitted from person to person through vertically or horizontally via contaminated body fluids. Despite the provision of an effective vaccine, it remains a major problem worldwide, particularly among the developing countries.

Methods

Online electronic databases including PubMed, Google Scholar, Science Direct, African Index Medicus, African Journals Online, and WHO Afro Library were searched and published articles from 2010 to June 8, 2019, were considered. Both authors independently screened articles and extracted the data. Funnel-Plots and Egger’s test statistics were used to determine the presence of small-study effects and publication bias. The pooled prevalence of HBV was analyzed using the random-effects model. The possible sources of heterogeneity was analyzed through subgroup analysis, sensitivity analysis, and meta-regression.

Results

The overall pooled prevalence of HBV was 6% and among subgroups, pregnant women, healthcare workers, and HIV positive patients accounted for 5% for each group. Relatively low prevalence (4%) was obtained among blood donors. The Egger’s test statistics (p = 0.747) indicated the absence of publication bias. In addition, from the sensitivity analysis, there was no influence on the overall effect estimate while removing a single study at a time. The level of heterogeneity was reduced among pregnant women, HIV positive and studies with unknown sampling techniques. After conducting meta-regression, province, study group, screening method, and quality of papers were identified as sources of heterogeneity.

Conclusions

The overall pooled prevalence of HBV in Ethiopia was high. Strengthening and scaling up of the scope of the existing vaccination program and implementing novel approaches including screen-and-treat could be implemented to reduce the burden of the disease. Generally, the study can provide current prevalence estimate of HBV that could vital for intervention to tackle the disease.

Knowledge gaps of STIs in Africa; Systematic review

Sexually Transmitted Infections (STIs) are ambiguous burden of tremendous health, social and economic consequences. The current systematic review was conducted in order to determine awareness and knowledge of Africans toward sexually transmitted infections, not only concerning HIV/AIDS, but also other STIs such as gonorrhea, syphilis, HBV, HCV and HPV. A systematic review of literature was conducted, studies were retrieved and selected after fulfilling the inclusion criteria as well as passing the assessment procedure. Related data was extracted, quantitative analysis was conducted among participants who responded to questions related to HIV, HBV, HCV, HPV or STIs knowledge, sensitivity analysis as well as subgroup analysis were also conducted. Seventy four articles addressing knowledge among 35 African countries were included and 136 questions were analyzed and synthesized. The question “does using condom reduces HIV transmission?” was answered by 1,316,873 Africans in 35 countries, 66.8% [95% Cl; 62.6, 70.9] answered yes. While the question “is sexual contact a possible route of HBV transmission?” was answered by 7,490 participants in 5 countries; 42.5% [95% Cl; 20.4, 64.7] answered yes. The differences observed among populations are highlighting the possibility for improvement by directing light toward specific populations as well as addressing specific awareness knowledge to ensure that the general as well as the related specific preventive knowledge is improved.

"It's just in that sea of things that I never cared about": perception of hepatitis B amongst university students in Aberdeen, North-East Scotland

Background

A significant proportion of international students at UK universities are from regions with medium to high hepatitis B prevalence rates. Understanding the perception of students regarding hepatitis B infection is crucial for the development of appropriate information and services for this population group.

Methods

Twenty semi-structured interviews were conducted with students from the University of Aberdeen. The following key areas were covered: knowledge, awareness, practices including testing, cultural and social aspects and general attitudes to health information and services. Interviews were transcribed verbatim and coded using a framework analysis approach.

Results

The participants acknowledged hepatitis B to be a serious disease yet did not consider themselves to be at risk. They felt able to go to their General Practitioner if concerned about hepatitis B but emphasised that there was no indication that this was required. There was a general lack of knowledge about the disease including confusion over other types of hepatitis. This was linked to the perceived lack of attention given to hepatitis B in, for example, sexual health education and disease awareness raising campaigns. The participants expressed a desire for information on hepatitis B to be relevant to the student population, easy to understand, socially acceptable and easily accessible on student portals and social media platforms.

Conclusions

Our study suggests that students in Aberdeen, North East Scotland lack knowledge and awareness of hepatitis B and do not perceive themselves as being at risk of hepatitis B infection. There is a need for more tailored hepatitis B messages to be incorporated into a range of contexts with clearer risk communication for the student population.

Seroprevalence of Hepatitis B Virus and Associated Factors among Health Professionals in University of Gondar Hospital, Northwest Ethiopia

Introduction

Hepatitis B virus infection is one of the commonest occupational risks in healthcare workers. However; there is limited evidence regarding the prevalence of hepatitis in health professionals in Ethiopia.

Objective

This study was aimed at assessing the prevalence of hepatitis B and associated factors in health professionals.

Methods

Institution based cross-sectional study was conducted among health professionals at University of Gondar Hospital from January to February, 2015. Self-administered questionnaire was used to collect sociodemographic variables and blood sample was also taken to determine hepatitis B virus sero-status. Chi square test with 95% confidence interval (CI) was computed to assess the associations of different factors with hepatitis B infection.

Result

A total of 332 health professionals (with a response rate of 92.2%) participated in the study. Most (98.5%) of health professionals were not vaccinated for hepatitis B. The prevalence of hepatitis B in health professionals at UOG hospital was found to be 4.52% (95% CI: 2.4, 6.5). Hepatitis B infection was more common among males (P value =0.0299).  Conclusion. The prevalence of hepatitis B in health professionals in this study was comparable with other studies done in Ethiopia among health professionals. Males were more affected than females for hepatitis B infection. Hepatitis B virus vaccine, treatment for the infected, and training on infection prevention should be more available for healthcare workers.

Seroprevalence and factors associated with hepatitis B virus infection among the hill tribe youths, northern Thailand

Background

Hepatitis B virus (HBV) infection is a major viral infection, particularly in people living in the Western Pacific region, including the hill tribe people living in northern Thailand. This study aimed to estimate the prevalence of HBV infection and to detect the factors associated with HBV infection among hill tribe youths in Thailand.

Methods

A cross-sectional study was conducted to estimate the prevalence and determine the factors associated with HBV infection among hill tribe youths living in northern Thailand. A validated questionnaire and 5 mL blood sample were used for data collection. The Wondfo Diagnostic Kit®, the Wondfo One Step HBsAg Serum/Plasma Test®, and the Wondfo One Step HBsAg Serum/Plasma Test® were used for anti-HBsAg, HBsAg, and total anti-HBc detections, respectively. Logistic regression was used to detect associations between variables with an α = 0.05 significance level.

Results

A total of 836 participants were included in the study; 62.7% were female, 58.9% were aged 15–17 years, 58.7% were Buddhist, 78.4% graduated high school, and 89.1% had no income. The majority were Akha (30.0%), Yao (16.3%), and Hmong (15.8%); 13.2% smoked, 21.5% used alcohol, 13.3% had tattoos, 3.9% experienced drug injection from illegal practitioners, and 35.7% had no history of HBV immunization. The prevalence of HBsAg was 3.0%; anti-HBs, 10.2%; and total anti-HBc, 8.1%. In the multivariate analysis, four variables were found to be significantly associated with HBV infection among the hill tribe youths: age, tribe, work experience, and number of partners. Those aged 18–20 years and 21–24 years had 2.13 times (95%CI = 1.35–3.29) and 2.39 times (95%CI = 1.05–3.90) greater odds of HBV infection, respectively, than those aged 15–17 years. Akha, Lahu, and Hmong youths had 3.12 times (95%CI = 1.07–9.12), 3.71 times (95%CI = 1.21–11.41), and 3.84 times (95%CI = 1.26–11.69) greater odds of HBV infection, respectively, than Lisu youths. Those who had experience working outside of the village had a 1.77 times (95%CI = 1.18–2.98) greater chance of HBV infection than those who did not have experience working outside of the village, and those who had ≥2 partners had a 2.66 times (95%CI = 1.96–3.87) greater chance of HBV infection than those who had no partner.

Conclusions

Effective HBV prevention programs should be promoted in Akha, Lahu, and Hmong youth populations, particularly to those who have sexual partners, work outside of the village and are aged 18–24 years.

Hepatitis B and C Viral Infection: Prevalence, Knowledge, Attitude, Practice, and Occupational Exposure among Healthcare Workers of Jimma University Medical Center, Southwest Ethiopia

Background

Blood-borne infections have been recognized as an occupational hazard for nearly 50 years. Current treatment for hepatitis B virus (HBV) is very expensive for individuals in developing countries and cannot clear infection after it progresses to the chronic stage. Thus, early screenings of people who are at higher risk like healthcare workers and vaccination and awareness creation on standard precautions (SP) to prevent transmission are mandatory. This study determined seroprevalence of HBV and hepatitis C virus (HCV) among healthcare workers of Jimma University Medical Center (JUMC).

Methods

An institution based cross-sectional study was conducted from Nov 2015 to Jan 2016. The lottery method was used to select 240 healthcare workers. Data were collected by a self-administered questionnaire. Five to ten milliliters of whole venous blood was collected from each participant. The blood samples were analyzed (tested) for hepatitis B surface antigen (HBsAg) and anti-HCV antibody using automated Enzyme-Linked Immunosorbent Assay (ELISA). Data were entered into EpiData 3.1 and analyzed by SPSS 23.

Results

The positivity of HBsAg was 2.5% (6/240; 95% CI: 0.52-4.48%) and that of anti-HCV antibody was 0.42% (1/240; 95% CI: 0.0-1.23%). Most participants had good knowledge of HBV (73.9%), HCV (60.9%), and SP (82.2%) and positive attitude towards SP (88.7%), but only 42.6% had a good practice of SP. More than half (60%) and nearly half (43%) had a history of ever exposure and exposure in the last one year before the survey, respectively. Females were at lower risk of both having ever exposure (95% CI: (0.241, 0.777)) and exposure in the last one year before the survey (95% CI: (0.297, 0.933)) compared to males.

Conclusion

The prevalence of HBV was intermediate according to the endemicity classification by WHO. The practice of SP was poor in most participants and, thus, occupational exposure was high. Therefore, regular screening and vaccination of healthcare workers, regular provision of basic or refresher training and availing logistics, and regular motivation of healthcare workers on the practice of standard precautions are recommended.

New horizons in hepatitis B and C in the older adult

Hepatitis C (HCV) and hepatitis B (HBV), are blood-borne viruses that can cause acute hepatitis; but are clinically relevant because chronic infection is associated with development of cirrhosis and hepatocellular carcinoma. Both these viruses are becoming more common in the older population, due to the ageing of generations exposed to the risk factors associated with infection; intravenous drug use, multiple sexual partners and men who have sex with men. This review will cover the natural history and epidemiology of these infections as well as the revolution in drug therapy that now allows cure of HCV infection and complete control of HBV infection.

Hepatitis viruses in Kathmandu, Nepal: hospital-based study

OBJECTIVE

The objective of this study was to see the aetiology and outcome of sporadic acute viral hepatitis (AVH) in Kathmandu, Nepal.

RESULTS

Among 210 patients, 94 (45%) were male and 116 (55%) were female. Mean age was 30 years. 52 (24.7%) out of 210 were positive for either of the hepatitis virus infection. Major causative agent for AVH among hepatitis positive patients were hepatitis E virus (HEV) in 36 (69.2%), followed by hepatitis A virus (HAV) 8 (15.3%), hepatitis B virus (HBV) 7 (13.4%) and hepatitis C virus (HCV) 1 (1.9%). The 158 (75.3%) patient were negative for all hepatitis viral markers. Co-infections with more than one virus were found in 4 (7.6%) patients. All liver-specific enzymes including bilirubin increased in hepatitis-infected patients. We found large number circulation of HEV in Kathmandu, Nepal, indicating that this region is endemic for hepatitis virus infection.
