Abstract
Despite the outstanding progress that has been made in the prevention, detection, and management of hepatitis B during the past decades, hepatitis B remains a problem among healthcare personnel (HCP) in many countries. We reviewed studies on all aspects of hepatitis B in HCP published from 2017 through April 2023. They revealed wide variations on the prevalence of infection among HCP, ranging from 0.6% in Europe to >8.7% in Africa, almost always in association with very low vaccination rates. Many studies found a significant association between HCP's knowledge about hepatitis B and hepatitis B vaccines, their vaccination status, and practices. This research also discloses global inequities regarding vaccination policies against hepatitis B, free-of-charge vaccinations, and access to post-exposure prophylaxis (PEP). Strategies to prevent and manage accidental exposures are needed in order to reduce the burden of hepatitis B on HCP, while written policies for all aspects of infection prevention, protective equipment, and PEP should be available. Lastly, HCP should be accordingly educated. These are all imperative given the decline of routine vaccinations in the COVID-19 era, particularly in countries with fragile vaccination programs, and the disruptions of interventions for hepatitis B that are expected to provide a pool of virus transmission to future generations.

[PMID: 38179572 PMCID: PMC10766012 DOI: 10.3389/fpubh.2023.1302183] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2023] [Accepted: 11/28/2023] [Indexed: 01/06/2024] Open
Abstract
Background China has long been with high Hepatitis B Virus(HBV) prevalence in the world. The HBV prevalence of people aged 1-59 decreased to less than 8% in 2006, and by 2020, HBsAg positive rate of children aged <5 decreased to less than <1% which was due to the free three-dose hepatitis B(HepB) immunization for newborns nationwide since 2002. Huangpu district was selected as one of the pilot areas for free Hep B vaccination in newborns since 1986, which formed an early protection in the population from mother-to-child transmission. However, the existed HBV infected people were still needed to be discovered, evaluated whether to receive antiviral therapies and intervened with health education in order to reduce the incidence of viral hepatitis related hepatocellular carcinoma (HCC) and also reach the goal to eliminate public health hazards of viral hepatitis by 2030. Objective To know HepB immunization status among people aged 1 to 69 in Huangpu district of Shanghai, and find out risk factors changes of HBV infection. Methods Cross-sectional study was applied to analyze the HepB immunization status and related risk factors by carrying out survey among 706 participants aged 1 to 69 years old. Blood samples were collected for detection of serological HBV markers including hepatitis B surface antigen(HBsAg), hepatitis B surface antibody(HBsAb) and hepatitis B core antibody(HBcAb). Participants with HBsAg positive were required to complete additional examinations such as alanine aminotransferase(ALT), aspartate aminotransferase(AST), total bilirubin, albumin, globulin, liver fibroscan and liver ultrasound. Results For participants aged 1 to 14, the positive rate of HBsAg, HBsAb and HBcAb was 0.00, 50.00 and 30.46%, respectively. The HBsAb positive rate reached a peak of 90.91% at 2 years old, and then showed a significant downward trend (χ2 = 55.612, p < 0.001). All the participants have completed three-dose Hep B vaccination, however for the second dose, those who vaccinated 30 days later than the appointed time(aged one month) got higher HBcAb prevalence than those who vaccinated on time(χ2 = 5.87, p = 0.015). Two mothers were found HBsAg positive, but there was no significant difference in children's HBcAb positive rates regardless of the mothers' HBsAg results. For participants aged 15 to 69, the positive rate of HBsAg, HBsAb and HBcAb was 4.21, 44.25 and 49.23%, respectively. Multivariate analysis for HBcAb positive among people aged 15 to 69 showed that age(50-69) and HBsAb positive were the risk factors for HBcAb positive(p < 0.05). Higher education was the protective factor for HBcAb positive(p < 0.05). After the screening for HBsAg, 22 participants were tested HBsAg positive and required additional examinations, and a total of 12 completed all the examinations. One participant was recognized as active HBV infection without antivirus treatment. Among the 12 participants, 2 have received antiviral treatment before and 4 had a history of HBV infection in family members. Conclusion In this study, HBsAg positive rate of those who aged 1 to 14 was 0.00%, which indicated that the HepB immunization has achieved a lot in protecting children from being infected. However, failing to get timely Hep B vaccination could be an influencing factor for HBcAb positive in children. As a result, additional tests for HBV DNA could be done to specify an HBV infection and more attention should be paid to the timeliness of Hep B vaccination in the next step. The HBcAb positive rate of people aged 1 to 69 was relatively higher than that of other provinces. Despite of the limited participants with full examinations, we should still put emphasis on HBV treatment and the possibility of transmission within families.

HBV Infection Is an Intermediate-Risk Disease, Whereas Anaemia Is a Mild-to-Moderate Public Health Problem in Young Ghanaian Adults: A Four-Year Retrospective Analysis of Students' Medical Records. BIOMED RESEARCH INTERNATIONAL 2023; 2023:9318984. [PMID: 37475793 PMCID: PMC10356218 DOI: 10.1155/2023/9318984] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 10/21/2022] [Revised: 06/22/2023] [Accepted: 06/26/2023] [Indexed: 07/22/2023]
Abstract
Background In sub-Saharan Africa, malaria, chronic viral diseases, nutritional deficiencies, and haemoglobinopathies are common causes of anaemia. Continual surveillance data is required to situate the anaemia and infectious disease burden within a given population. This study determined the 4-year trends of anaemia, hepatitis B virus (HBV), and HCV infections and factors associated with anaemia in young Ghanaian adults. Methods This retrospective study analysed the medical records of 21,716 fresh students at the University of Cape Coast. Data was presented as percentages and line graphs to show the yearly trends in anaemia, HBV, and HCV infections. Binary logistic regression was used to determine the increased odds of anaemia in participants. Results Although the 4-year anaemia prevalence was 14.2% (95% CI: 0.1403-0.1498), anaemia prevalence in women and men were 24.1% (95% CI: 0.2387-0.2562) and 6.6% (95% CI:0.0616-0.0705), respectively. Anaemia prevalence consistently remained mild (males) and moderate (females) public health problem over the four-year period. Adolescents were more represented in the anaemic group (18.7% prevalence), 70.9% of them being females. The prevalence of HBV and HCV infections were 5.4% (95% CI:0.0506-0.0567) and 0.9% (95% CI: 0.0082-0.0108), respectively; only 0.1% of participants had HBV and HCV coinfection. Males were more represented in both HBV (71.2%) and HCV (63.7%) infection groups. Moreover, 15.8% of the participants who were seropositive for HBsAg self-reported having previously been vaccinated, suggesting a breakthrough infection and/or vaccine nonresponse. Furthermore, female (COR: 4.545; p < 0.001), teenagers (COR: 1.697; p < 0.001), 20-29 years (COR: 1.221; p = 0.035), and positive sickling slide test (COR: 1.176; p = 0.003) were statistically significantly associated with increased odds of anaemia. Conclusion Intentional preventative public health campaigns regarding anaemia, HBV, and HCV infection should, respectively, target females and young adult males to increase chances of making real change in behavioural attitudes in these at-risk groups.

Abstract
Introduction The World Health Organization estimates that 37% of Hepatitis B Virus (HBV) infections among Health Care Workers (HCWs) are due to percutaneous occupational exposure to blood and body fluids. In Ghana, occupational exposures are rising; however, the burden of HBV infection in HCWs remains unknown. Our study estimated the prevalence of HBV surface antigens and associated factors among HCWs. Methods We conducted a cross-sectional survey of 340 HCWs using a structured pretested questionnaire and screening for HBV surface antigens. Data were analyzed using SPSS version 20.0 with a level of significance set at <0.05. Results The overall crude prevalence of current HBV infection was 5.9 % (95% CI, 3.0-8.0). Adjusted prevalence by test performance was 5.8%. Prevalence was highest among males 10.2% (95% CI, 4.8-18.5), HCWs other than nurses and doctors 9.2% (95% CI, 4.5-16.2), and those working at lower-level facilities 9.7% (95% CI, 4.8-17.1). Training in the prevention of blood-borne infections was significantly associated with HBV infection (adjusted odds ratio 3.2; 95% CI, 1.1-9.1). Conclusions HBV infection is high in this population. In addition to lifesaving interventions such as vaccination and the use of immunoglobulin, training in blood-borne infections could prevent new HBV infections among Ghanaian HCWs.

Abstract
Hepatitis B virus (HBV) and hepatitis delta virus (HDV) are highly prevalent viruses estimated to infect approximately 300 million people and 12-72 million people worldwide, respectively. HDV requires the HBV envelope to establish a successful infection. Concurrent infection with HBV and HDV can result in more severe disease outcomes than infection with HBV alone. These viruses can cause significant hepatic disease, including cirrhosis, fulminant hepatitis, and hepatocellular carcinoma, and represent a significant cause of global mortality. Therefore, a thorough understanding of these viruses and the immune response they generate is essential to enhance disease management. This review includes an overview of the HBV and HDV viruses, including life cycle, structure, natural course of infection, and histopathology. A discussion of the interplay between HDV RNA and HBV DNA during chronic infection is also included. It then discusses characteristics of the immune response with a focus on reactions to the antigenic hepatitis B surface antigen, including small, middle, and large surface antigens. This paper also reviews characteristics of the immune response to the hepatitis D antigen (including small and large antigens), the only protein expressed by hepatitis D. Lastly, we conclude with a discussion of recent therapeutic advances pertaining to these viruses.

Abstract
Abstract
Aim
This study aimed to assess factors associated with the willingness to be vaccinated against hepatitis B among Indonesia’s adult population, considering cultural and geographic differences by analysing the two provinces of Aceh and Yogyakarta.
Subject and methods
An institution-based cross-sectional survey was conducted in 16 community health centres. A multivariable logistic regression model stratified by province was employed to assess variables associated with the willingness to receive hepatitis B vaccination.
Results
We found that participants from Yogyakarta more often had a higher knowledge and risk perception of hepatitis B and were more often willing to get vaccinated than participants from Aceh. We also found that a high-risk perception of hepatitis B infection was associated with the willingness to be vaccinated against hepatitis B in participants from both Aceh and Yogyakarta. Furthermore, in Yogyakarta, a fair and high knowledge of hepatitis B infection and vaccination, being female, and having health insurance covering hepatitis B vaccination costs were associated with the willingness to be vaccinated. In Aceh, health care workers in high-risk units for hepatitis B had a higher willingness to be vaccinated than those who were not high-risk health care workers.
Conclusion
Given the different factors associated with the willingness to be vaccinated against hepatitis B in Aceh and Yogyakarta, this study also highlights the need of a locally adjusted, culture-based approach to improve the hepatitis B vaccination programme.

Abstract
Introduction The hepatitis B virus (HBV) is a blood-borne virus that can be transmitted by percutaneous and mucocutaneous contact with infected bodily fluid. Healthcare workers (HCWs) are more exposed to HBV infection. They must have a thorough understanding of HBV infection since they can contract and spread the virus. In this study, we systematically reviewed all published evidence on the seroprevalence of Hepatitis B virus (HBV) infection among HCWs. and synthesize evidence on the association between knowledge and awareness with HBV infection. Methods We searched PubMed, EMBASE, Cochrane Library and Scopus for studies reporting on HBV seroprevalence from January 1997 to September 2021 among healthcare workers. We used random-effects meta-analyses to estimate the pool prevalence of HBV infection. Results We identified 25 studies that met our inclusion criteria, with data on 10,043 adults from 11 countries and two regions: Africa and Asia. The overall seroprevalence of HBV was 5.0% (95% confidence interval [CI] 3.6%), with Africa reporting higher estimates (5.0%, 95% CI 3.7%) than Asia population (4.0%, 95% CI 1.9%). The highest pooled prevalence estimate in African countries came from studies published in the Cameroon region (8.0%, 95% CI 5–10%) while the lowest came from Ethiopia (4.0%, 95% CI 2.6%). The overall seroprevalence estimates in the African population were significantly higher than those in the Asian group. Studies in Africa found that the average knowledge and seroprevalence were 1.4% and 11.0%, respectively where, eight studies (53.3%) reported good knowledge and seven studies (46.7%) reported average knowledge. In Asia, two studies (40.0%) reported good knowledge, one study (20.0%) reporting average knowledge, and two studies (40.0%) reporting poor knowledge. African studies demonstrated good knowledge despite the fact that their HBV infection rate was higher than 6.7%. Conclusion Africa and Asia have the highest seroprevalence of HBV infection. Improving the comparability of epidemiological and clinical studies constitutes an important step forward. More high-quality data is needed to improve the precision of burden estimates.

INFECTIOUS DISEASES: RESEARCH AND TREATMENT 2022; 15:11786337211062622. [PMID: 35023926 PMCID: PMC8744165 DOI: 10.1177/11786337211062622] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/11/2021] [Accepted: 11/08/2021] [Indexed: 11/17/2022]
Abstract
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.

Abstract
Background Hepatitis B and C lead to chronic disease in hundreds of millions of people and together constitute the most common cause of liver cirrhosis and cancer with attendant mortality. Objective The objective of this study was to estimate the prevalence of hepatitis B and C virus infection among different categories of health-care workers, looking at the exposure to patients' samples and the prevalence rate among these categories of health workers. This will help to ascertain the risk and the need to pay more attention to preventive measures. Materials and Methods This was a cross-sectional study conducted over a 2-year period among 217 health-care workers at the department of Haematology of the Federal Teaching Hospital, Ido-Ekiti, Nigeria. Respondents were randomly selected, and blood samples were taken for the hepatitis B and C screening. Data were analyzed using SPSS 20; bivariate analyses were done, and the level of statistical significance was set at P < 0.05. Results A total of 13 (6.0%) tested positive for HBsAg. Analysis of the marital status of those that tested positive to Hepatitis B, revealed that the highest number (77%) was found among the married, while the singles and the divorced constitute 15.3% and 7.7% respectively. The nurses and nonhealth professionals (admin staff) constitute the highest positive yield of hepatitis B virus (HBV), followed by medical doctors and laboratory staff. The age of the respondent was found to have a statistically significant association with HBV serology (P < 0.05). Conclusion There is a comparatively lower prevalence of HBsAg among the health-care workers who are directly exposed to patients' samples. The age of the respondent has a significant association with hepatitis B infection.

Abstract
ObjectivesUsing secondary data from 208 079 Rwandans, we determined the prevalence of chronic hepatitis B virus (HBV) infection among high-risk groups and its demographic, geographical and health-related determinants.DesignIn this cross-sectional study, we obtained and analysed data from a national hepatitis B vaccination and screening campaign conducted in Rwanda in 2017. We performed logistic regression to examine associations between chronic HBV infection and related factors such as risk status and geographical characteristics.SettingIndividuals were sampled nationally in all 30 districts across 4 provinces and the city of Kigali and all prisons in Rwanda.ParticipantsThe study involves 208 079 individuals at high risk including prisoners and other high-risk groups (oHRG).Main outcomeThe primary outcome for our study was hepatitis B surface antigens (HBsAg) prevalence.FindingsFrom 208 079 adults participants, 206 517 (99.2%) had valid HBsAg results, 4.3% of 64 944 prisoners and 4.0% of 140 985 oHRG were HBV positive. The prevalence was higher in Northern Province 5.1%, (95% CI 4.8 to 5.4). In multivariate analysis, the odds of infection decreased with increasing age, and hepatitis C antibody positivity reduced the odds for chronic HBV (OR 0.58, 95% CI 0.52 to 0.66 and OR 0.74, 95% CI 0.62 to 0.89 among oHRG and prisoners, respectively). In addition, being female was associated with lower odds of HBV (OR 0.70, 95% CI 0.66 to 0.74 and OR 0.80, 95% CI 0.65 to 0.98 among oHRG and prisoners, respectively).ConclusionWe found that individuals below 55 years of age and individuals who belong to high-risk groups (ie, sex workers, injection drug users, men who have sex with men, etc) have a higher probability of chronic HBV infection. Infection with chronic hepatitis C virus was not correlated with chronic HBV infection in our study population. Potential explanations include differential routes of transmission, specific immunological and pathophysiological factors or different effects of health prevention and control programmes.

Abstract
OBJECTIVES Vietnam is an endemic area for hepatitis B virus and hepatitis C virus infection (HBV-HCV), yet its largest city, Ho Chi Minh City (HCMC), has no comprehensive policy to educate, screen, treat and protect healthcare workers (HCWs) from viral hepatitis. We conducted a mixed-methods study to document HBV-HCV infection rates, risk factors, local barriers and opportunities for providing education, screening and medical care for HCWs. DESIGN This mixed-methods study involved an HBV and HCV serological evaluation, knowledge, attitude and practice survey about viral hepatitis and many in-depth interviews. Descriptive statistics and thematic content analysis using inductive and deductive approaches were used. SETTING HCMC, Vietnam. PARTICIPANTS HCWs at risk of viral hepatitis exposure at three hospitals in HCMC. RESULTS Of the 210 invited HCWs, 203 were enrolled. Of the 203 HCWs enrolled, 20 were hepatitis B surface antigen-positive, 1 was anti-hepatitis C antibody (anti-HCV Ab)-positive, 57 were anti-hepatitis B core Ab-positive and 152 had adequate anti-hepatitis B surface Ab (anti-HBs Ab) titre (≥10IU/mL). Only 50% of the infected HCWs reported always using gloves during a clinical activity involving handling of blood or bodily fluid. Approximately 50% of HCWs were still not vaccinated against HBV following 1 year of employment. In-depth interviews revealed two major concerns for most interviewees: the need for financial support for HBV-HCV screening and treatment in HCWs and the need for specific HBV-HCV guidelines to be independently developed. CONCLUSIONS The high HBV infection rate in HCWs coupled with inadequate preventive occupational practices among the population in HCMC highlight the urgent needs to establish formal policy and rigorous education, screening, vaccination and treatment programmes to protect HCWs from HBV acquisition or to manage those living with chronic HBV in Vietnam.

Risk of HBV infection among male and female first-time blood donors born before and after the July 1986 HBV vaccination program in Taiwan. BMC Public Health 2021; 21:1831. [PMID: 34627173 PMCID: PMC8502303 DOI: 10.1186/s12889-021-11846-x] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2021] [Accepted: 09/21/2021] [Indexed: 12/16/2022] Open
Abstract
Background In July 1984, Taiwan officially began a nationwide hepatitis B virus (HBV) vaccination program where only infants born to HBsAg-positive mothers were vaccinated free of charge until June 1986. However, from July 1986, all infants were vaccinated against HBV. The impact of the July 1986 HBV vaccination program on first-time blood donors has not been exhaustively studied. We, therefore, determined the risk of HBV among male and female first-time blood donors born before and after the July 1986 HBV vaccination program in Taiwan. Methods Initially, we recruited 857,310 first-time blood donors whose data were collected between 2013 and 2018 from 5 blood donation centers in Taiwan. However, we excluded donors with incomplete and outlying data (n = 12,213) and those born between July 1984 and June 1986 (n = 21,054). The final study participants comprised 9118 HBV positive and 814,925 HBV negative individuals. We divided the participants into two birth cohorts (born before and after July 1986) and assumed that those born before July 1986 were not vaccinated at birth while those born after July 1986 were vaccinated. Results The prevalence of HBV among those born before and after July 1986 was 4.53 and 0.25%, respectively. Individuals born after July 1986 had a lower risk of HBV than those born before July 1986. The adjusted odds ratio (OR), 95% confidence interval (CI) was 0.16, 0.13–0.19. Men had a higher risk of HBV than women (OR = 1.40, 95% CI = 1.34–1.47). The interaction between sex and birth date was significant (p-value = 0.0067). Stratification of participants by birth date revealed a higher risk of HBV in men compared to women in both birth cohorts. The OR, 95% CI was 1.47, 1.40–1.55 for those born before July 1986 but declined to 1.15, 1.02–1.29 for those born after July 1986. Conclusions The risk of HBV was lower among those born after than those born before the July 1986 vaccination program. In both cohorts, the risk was high in men relative to women. The seemingly protective effect among those born after July 1986 was higher in women than men.

Trans R Soc Trop Med Hyg 2021; 115:1106-1113. [PMID: 33772308 PMCID: PMC8486739 DOI: 10.1093/trstmh/trab054] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2020] [Revised: 12/21/2020] [Accepted: 03/12/2021] [Indexed: 02/06/2023] Open
Abstract
There are no comprehensive data on viral hepatitis from Sierra Leone; however, a huge disease burden has been observed in different subpopulations. This review summarizes available data on hepatitis B and C virus (HBV and HCV) prevalence in Sierra Leone and identifies knowledge gaps. Despite the non-uniformity of the studies and the lack of systematic case recording, different reports published in recent decades yielded a hepatitis B prevalence of 8.7% among healthcare workers, 11.3% among pregnant women, 15.2% among blood donors and 16.7% in school-age children. The actual HBV prevalence in the general population was reported as 21.7%; similar to what was reported for people living with human immunodeficiency virus (PLHIV). HCV prevalence is 8% and 7% in male and female blood donors, respectively, 4.1% in PLHIV and 2.0% in school children. There are significant knowledge gaps regarding the prevalence of viral hepatitis B and C in Sierra Leone, despite the high burden reported in a few studies. There are limited programmatic interventions on the control and prevention of viral hepatitis in the country. Therefore, well-structured representative studies should provide a solid understanding of the true prevalence of hepatitis B and C to inform best possible public health measures in Sierra Leone.

Prevalence and predictors of hepatitis B virus (HBV) infection in east Africa: evidence from a systematic review and meta-analysis of epidemiological studies published from 2005 to 2020. Arch Public Health 2021; 79:167. [PMID: 34537079 PMCID: PMC8449462 DOI: 10.1186/s13690-021-00686-1] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2021] [Accepted: 09/02/2021] [Indexed: 12/16/2022] Open
Abstract
BACKGROUND The epidemiology of hepatitis B virus (HBV) in the general population in east Africa is not well documented. In this meta-analysis, we examined 37 full published research articles to synthesise up-to-date data on the prevalence and predictors of the HBV burden for the effective prevention and management of the virus in our region. METHODS We examined 37 full published research articles found using PubMed, Scopus, African Journal Online (AJOL), and Google Scholar between May and October 2020. Dichotomous data on HBV prevalence and predictors of infection were extracted from the individual studies. The HBV prevalence, test of proportion, relative risk, and I2 statistics for heterogeneity were calculated using MedCalc software version 19.1.3. Begg's tests was used to test for publication bias. Sources of heterogeneity were analysed through sensitivity analysis, meta-regression, and sub-group analysis at 95% CI. P < 0.05 was considered significant for all analyses. RESULTS The prevalence of HBV was generally high (6.025%), with publications from Kenya (8.54%), Uganda (8.454%) and those from between 2011 and 2015 (8.759%) reporting the highest prevalence (P < 0.05). Blood transfusion, scarification, promiscuity, HIV seropositivity, and being male were independent predictors significantly associated with HBV infection (P < 0.05), with the male sex being the most strongly associated predictor of HBV infection. Meta-regressions for the pooled HBV prevalence and sample size, as well as the year of publication, lacked statistical significance (P > 0.05). Omitting the study with the largest sample size slightly increased pooled HBV prevalence to 6.149%, suggesting that the studies are robust. Begg's test showed no evidence of publication bias for overall meta-analysis (p > 0.05). CONCLUSION The burden of HBV is still high, with the male sex, blood transfusion, body scarification, and HIV seropositivity being potential predictors of infection. Thus, it is important to scale up control and prevention measures targeting persons at high risk.

Abstract
BACKGROUND Nursing fraternity are at an increased risk of acquiring hepatitis B and hepatitis C infections mainly attributable to occupational risk and close contact with the patients while treatment. However, unawareness and negligence about the severity, mode of transmission and preventive measures about the disease can further predispose the nursing fraternity to a higher risk of infection. To overcome these lacunae in knowledge, a training program named Project PRAKASH was initiated for in-service nurses across the country. The objective of the program was to impart up-to-date knowledge to the nursing professionals in the management of viral hepatitis and to assess the effectiveness of the training program through pre-post-knowledge assessment survey. METHODOLOGY One-day training program titled 'Hepatitis Induction Program' was conducted for a period of 2 years (2018-2020) among nursing professionals. It was accompanied by administration of 54-item knowledge, attitude and practice (KAP) questionnaire with four sections: demographic details, knowledge (30 items), attitude (11 items) and practice (13 items), followed by post-knowledge assessment. An Impact Assessment Survey (IAS) was also administered to assess the change in attitude and practice among 10% of the attendees, at least 6 months post training. RESULT A total of 32 one-day training programmes were organised which witnessed the training of 5,253 nursing professionals from 292 institutions across 12 states. A data of 4,474 participants were included in the final analysis: improvement in the knowledge score was significant (P-value < 0.001) with mean knowledge score of 19.3 ± 4.4 in pre-test and 25.7 ± 3.9 in the post-test. CONCLUSION The one-day training resulted in improvement of knowledge and significant changes in the attitude and practices of the nursing professionals.

Abstract
Background Methadone therapy clinics have been recently introduced in Tanzania, aiming at reducing risk behaviors and infection rates of viral hepatitis and HIV among people who use drugs. The objective of this study was to estimate the prevalence, associated factors and knowledge level of these conditions among people who use drugs attending a methadone clinic in Tanzania. Methods We enrolled 253 People who using drugs receiving Methadone therapy. Clinical data was retrospectively collected from the medical records and face-to face interviews were conducted to determine the behavioral risk factors and respondents’ knowledge on viral hepatitis and HIV. Results An overall seroprevalence of viral hepatitis (either hepatitis B surface antigen or anti-hepatitis C virus) was 6.3%, while that of hepatitis B virus mono infection was 3.5% and anti-hepatitis C antibodies was 3.5%. Seroprevalence of HIV was 12.6%. Viral hepatitis was strongly predicted by advanced age (> 35 years) (p = 0.02) and staying at Kirumba area (p = 0.004), and HIV infection was predicted by increased age (> 37 years) (p = 0.04) and female sex (p < 0.001). Regarding the knowledge of viral hepatitis, majority of the respondents were unaware of the transmission methods and availability of hepatitis B virus vaccines and only 17% were classified as well informed (provided ≥4 correct answers out of 7 questions). Good knowledge was highly predicted by higher education level of the individual (p = 0.001). Conclusions Despite the efforts to curb viral hepatitis and HIV infections through Methadone clinics, infection rates among people who use drugs are still high and the general knowledge on preventive measures is inadequate.

Abstract
BACKGROUND Healthcare workers are at risk of acquiring hepatitis B and C virus infections through patients' blood and bodily fluids exposure. So far, there is no pooled data that shows the prevalence of HBV and HCV among health care workers in Africa. This study aimed to determine the pooled prevalence of hepatitis B and C infections among health care workers in Africa. METHODS Studies reporting the prevalence of HBV and HCV were identified from major databases and gray literature. PubMed, CINAHL, POPLINE, ScienceDirect, African Journals Online (AJOL), and Google Scholar were systematically searched to identify relevant studies. A random-effect model was used to estimate the pooled prevalence of hepatitis B and C among health care workers in Africa. The heterogeneity of studies was assessed using Cochran Q statistics and I2 tests. Publication bias was assessed using Begg's tests. RESULT In total, 1885 articles were retrieved, and 44 studies met the inclusion criteria and included in the final analysis. A total of 17,510 healthcare workers were included. The pooled prevalence of hepatitis B virus infection among health care workers in Africa is estimated to be 6.81% (95% CI 5.67-7.95) with a significant level of heterogeneity (I2 = 91.6%; p < 0.001). While the pooled prevalence of hepatitis C virus infection using the random-effects model was 5.58% (95% CI 3.55-7.61) with a significant level of heterogeneity (I2 = 95.1%; p < 0.001). CONCLUSION Overall, one in fifteen and more than one in twenty healthcare workers were infected by HBV and HCV, respectively. The high burden of HBV and HCV infections remains a significant problem among healthcare workers in Africa.

Transfusion-Transmitted Infections and associated risk factors at the Northern Zone Blood Transfusion Center in Tanzania: A study of blood donors between 2017 and 2019. PLoS One 2021; 16:e0249061. [PMID: 33760870 PMCID: PMC7990303 DOI: 10.1371/journal.pone.0249061] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2021] [Accepted: 03/10/2021] [Indexed: 12/03/2022] Open
Abstract
Background Blood transfusion saves many people every year that would otherwise have died. The present study aimed to provide an update and insightful information regarding prevalence of the common Transfusion-Transmitted Infections (TTIs) and associated factors among blood donors in Tanzania. Methods This was a cross-sectional study involving retrospectively collected data of blood donors from the Tanzania Northern Zone Blood Transfusion Center between 2017 and 2019. Descriptive statistics were performed to describe characteristics of the blood donors. Univariable and multivariable logistic regression analyses were performed to determine association between prevalence of TTIs and socio-demographic factors. P-value <0.05 was considered statistically significant. Results A total of 101, 616 blood donors were included in the present study of which 85,053(83.7%) were males while 16,563 (16.3%) were females. Of all participants, the majority 45,400 (44.7%) were aged between 18 and 25 years; 79,582 (78.3%) were voluntary non-remunerated donors while 22,034 (21.7%) were replacement donors. The vast majority of them 99,626 (98%) were first time blood donors while 1990 (2%) were multiple donors. The overall prevalence of TTIs was 10.1% (10,226 out of 101,616) of which the leading was HBV accounting for 5.1% (5,264 out of 101,616). Being a replacement donor was associated with all the four types of TTIs: HIV (AOR = 1.22, 95% CI = 1.10–1.35), HBV (AOR = 1.35, 95% CI = 1.27–1.44), HCV (AOR = 1.28, 95% CI = 1.12–1.46), and syphilis (AOR = 1.33, 95% CI = 1.20–1.48). Conclusions Our study has demonstrated that Tanzania has relatively high prevalence of TTIs compared to some countries in Sub-Saharan Africa. HBV infection seems to be the most common infection among blood donors and replacement blood donors are at a higher risk of harboring the commonest TTIs among blood donors.

Abstract
BACKGROUND AND AIMS Sub-Saharan Africa (SSA) is the region with the most patients co-infected with the human immunodeficiency virus (HIV) and the hepatitis B virus (HBV) worldwide. However, few studies have focused on SSA children who are at a higher risk of developing a chronic infection than adults. Furthermore, children on first-line antiretroviral therapy (ART) including low genetic barrier drugs may develop both HBV and HIV resistance mutations. The aim of this work was to document HIV-HBV co-infection and to characterize the HBV isolates in children in Senegal. METHODS This is a retrospective study of 613 children infected with HIV on ART or not. Dried blood spot (DBS) specimens were used to detect hepatitis B surface antigen (HBsAg) with a rapid diagnostic test (RDT). Confirmation of HBsAg status and hepatitis B e antigen (HBeAg) detection was performed on an automated platform using the chemiluminescence assay technology. HBV viral DNA was quantified by real-time polymerase chain reaction (PCR) and the preS1/preS2/HBsAg region was genotyped by nested PCR followed by sequencing using the Sanger technique. RESULTS The prevalence of HIV-HBV co-infection was 4.1% (25/613). The median age of co-infected children was 13 years (2 years-16 years) and 40% (10/25) were girls. Almost all 19/20 (95%) were infected with HIV-1 and 79% (19/24) were treated with 3TC-based triple combination ART. The median duration of time on ART was 15 months (3 months-80 months). More than half of the children 53% (9/17) were experiencing HIV virologic failure and 75% (6/8) had at least one HIV-related resistance-associated mutation (RAM). Of the six children with resistance, none of the three administered treatments were effective on HIV. Of the 25 co-infected children, 82% (18/22) were HBeAg-positive, while the median HBV viral load (VL) was 6.20 log10 IU/mL (24/25 patients), and 62,5% (10/16) of the children had a persistent HBV viremia. Combination of ART was the only factor associated with HBV viremia persistence. Amplification was successful in 15 out of 16 patients (rate of 94%), and the ensuing phylogenetic analysis revealed that eight strains (53%) belonged to genotype A and seven (47%) to genotype E. HBV-related 3TC RAMs were uncovered in 20% of these patients (3/15). HBsAg escape mutations were found in 20% of the children (3/15). CONCLUSIONS Our results showed a high level of drug resistance mutations to both HIV and HBV, a significant level of HBsAg escape mutations, HBV DNA persistence and HIV virologic failure in co-infected children in Senegal. The HBV genotypes found were A and E.

Hepatitis B virus infection and its associated factors among medical waste collectors at public health facilities in eastern Ethiopia: a facility-based cross-sectional study. BMC Infect Dis 2021; 21:233. [PMID: 33639871 PMCID: PMC7912495 DOI: 10.1186/s12879-021-05918-x] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2020] [Accepted: 02/17/2021] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND The risk of hepatitis B virus infection among medical waste handlers who undergo collection, transportation, and disposal of medical wastes in the health institutions is higher due to frequent exposure to contaminated blood and other body fluids. There is limited evidence on the seroprevalence of hepatitis B among medical waste handlers in eastern Ethiopia. The study was aimed at studying the seroprevalence of Hepatitis B Virus and associated risk factors among medical waste collectors at health facilities of eastern Ethiopia. METHODS A facility-based cross-sectional study was conducted among randomly selected medical waste collectors from public health facilities in eastern Ethiopia from March to June 2018. A pre-tested and well-structured questionnaire was used to collect data on socio-demographic characteristics and hepatitis B infection risk factors. A2.5ml venous blood was also collected, centrifuged and the serum was analyzed for hepatitis B surface antigen using the instant hepatitis B surface antigen kit. Descriptive summary measures were done. Chi-square and Fisher exact tests were used to assess the risk of association. Multivariate logistic regression was conducted with 95% CI and all value at P-value < 0.05 was declared statistically significant. RESULTS From a total of 260 (97.38%) medical waste collectors participated, HBV was detected in 53 (20.4%) of the participants [95%CI; 15.8, 25.6]. No significant differences were observed in the detection rates of HBV with respect to socio-demographic characteristics. In both bivariate and multivariable logistic regression analysis, being unvaccinated (AOR = 6.35; 95%CI = [2.53-15.96], P = 0.001), history of blood transfusion (receiving) (AOR; 3.54; 95%CI; [1.02-12.24], P = 0.046), history of tattooing (AOR = 2.86; 95%CI = [1.12-7.27], p = 0.03), and history of multiple sexual partner (AOR = 10.28; 95%CI = [4.16-25.38], P = 0.001) remained statistically significantly associated with HBsAg positivity. CONCLUSION This cross-sectional study identified that HBV infection is high among medical waste collectors in eastern Ethiopia. Immunization and on job health promotion and disease prevention measures should be considered in order to control the risk of HBV infection among medical waste collectors in eastern Ethiopia.

Abstract
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.

Virol J 2020; 17:170. [PMID: 33160386 PMCID: PMC7648981 DOI: 10.1186/s12985-020-01443-6] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2020] [Accepted: 10/27/2020] [Indexed: 12/14/2022] Open
Abstract
Background There is plenitude of information on HIV infection among pregnant mothers attending antenatal care (ANC) in sub-Saharan Africa. However, the epidemiology of HBV–HIV co-infections in the same cohort is not clear despite the common route of transmission of both viruses. The aim of our study was to synthesize data on the prevalence of HBV–HIV co-infection among pregnant women attending ANC in Sub-Saharan Africa to assist in the design of public health interventions to mitigate the challenge.
Methods The study was done in tandem with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) standards and the Cochran’s Q test, I2 statistics for heterogeneity and the prevalence were calculated using commercially available software called MedCalcs (https://www.medcalc.org). A random effect model was used to pool the prevalence since all the heterogeneities were high (≥ 78%) and Phet < 0.05 indicated significant heterogeneities. The risk factors and risk differences for HBV–HIV co-infection were analyzed. Any likely sources of heterogeneity were analyzed through sensitivity analysis, meta-regression and sub-group analysis. All analyses were done at 95% level of significance and a P < 0.05 was considered significant. Results The overall pooled prevalence of HBV–HIV co-infection among pregnant mothers in sub-Saharan Africa was low 3.302% (95%CI = 2.285 to 4.4498%) with heterogeneities (I2) of 97.59% (P > 0.0001). Within regional sub group meta-analyses, West Africa had significantly higher prevalence of 5.155% (95% = 2.671 to 8.392%) with heterogeneity (I2) of 92.25% (P < 0.0001) than any other region (P < 0.001). Articles published from 2004–2010 had significantly higher prevalence of 6.356% (95% = 3.611 to 9.811%) with heterogeneity (I2) 91.15% (P < 0.0001) compared to those published from 2011 to 2019 (P < 0.001). The HIV positive cohort had significantly higher prevalence of HBV–HIV co-infection of 8.312% (95% CI = 5.806 to 11.22%) with heterogeneity (I2)94.90% (P < 0.0001) than the mothers sampled from the general population with a prevalence of 2.152% (95% CI = 1.358 to 3.125%) (P < 0.001). The overall and sub group analyses had high heterogeneities (I2 > 89%, P < 0.0001) but was reduced for South Africa (I2) = 78.4% (P = 0.0314). Age, marital status and employment were independent factors significantly associated with risk of HBV–HIV co-infection (P < 0.001) but not extent of gravidity and education level (P > 0.05). After meta-regression for year of publication and sample size for HBsAg positivity, the results were not significantly associated with HBV pooled prevalence for sample size (P = 0.146) and year of publication (P = 0.560). Following sensitivity analysis, the HBsAg pooled prevalence slightly increased to 3.429% (95% CI = 2.459 to 4.554%) with heterogeneity I2 = 96.59% (95% CI = 95.93 to 97.14%), P < 0.0001 Conclusion There is an urgent need for routine HBV screening among HIV positive pregnant mothers attending antenatal care in sub-Saharan Africa to establish the extent of HBV–HIV co-infection in this cohort. Future studies need to investigate the putative risk factors for HBV–HIV co-infection and prioritize plausible control strategies.

Abstract
Despite the heavy disease burden posed by hepatitis B, around 90% of people living with hepatitis B are not diagnosed globally. Many of the affected populations still have limited or no access to essential blood tests for hepatitis B. Compared to conventional blood tests which heavily rely on centralised laboratory facilities, point-of-care testing for hepatitis B has the potential to broaden testing access in low-resource settings and to engage hard-to-reach populations. Few hepatitis B point-of-care tests have been ratified for clinical use by international and regional regulatory bodies, and countries have been slow to adopt point-of-care testing into hepatitis B programs. This review presents currently available point-of-care tests for hepatitis B and their roles in the care cascade, reviewing evidence for testing performance, utility, acceptability, costs and cost-effectiveness when integrated into hepatitis B diagnosis and monitoring programs. We further discuss challenges and future directions in aspects of technology, implementation, and regulation when adopting point-of-care testing in hepatitis B programs.

Abstract
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.

Abstract
Background Tanzania has witnessed a significant decrease in the prevalence of human immunodeficiency virus (HIV) and viral hepatitis in the general population attributed to several interventional measures. It is uncertain whether this decline has also occurred among people who inject drugs (PWID). This study aimed to determine the seroprevalence of HIV, Hepatitis B and C viruses infection among PWID recruited from their hotspot sites in Dar es Salaam, Tanzania. Methods A cross-sectional study conducted between June and September 2017 recruited PWID from pre-identified hotspot sites using a snowball referral sampling technique. A structured questionnaire was used to obtain information regarding socio-demographic characteristics, behaviour and drug use. Blood was tested for the presence of IgG antibodies against HIV and Hepatitis C virus (HCV) and hepatitis B surface antigen (HBsAg). Data were entered in the computer using excel software and analysed using Statistical Package for Social Sciences version 20. Results A total of 219 PWID were recruited, the majority of whom were males (74.9%), unmarried (60.7%), had low education (62.6%) and low income (57.1%). The median age was 39 years, with an inter-quartile range of 35–43. Approximately 32.0% had a history of drug injection for more than 3 years, 79.9% were injecting drugs more than 3 times per day and 47.5% were sharing needles. The overall prevalence of HIV, HBsAg, and HCV was 33.8, 7.8, and 50.2%, respectively. There was serologic evidence of at least one infection for 68.9%, while 22.4% had two or more infections. HIV infection was independently associated with being married, while HCV was associated with injecting drugs for more than 3 years and unprotected sex. Conclusion Over two-third of PWID had serologic evidence of infection with at least one virus while 22.4% having at least two infections. The high prevalence of HIV and viral hepatitis infections among PWID may hamper initiatives of ending HIV and viral hepatitis epidemics in Tanzania.

Abstract
Objective This study aimed to determine the magnitude of serum HBsAg and the risk factors for hepatitis B virus infection among pregnant women in Bahir Dar. An institution based cross sectional study was implemented from February 1 to May 1, 2018 among 338 pregnant women attending antenatal care clinic at Felegehiwot referral hospital, Bahir Dar, 2018. Systematic random sampling technique was implemented. Blood sample was taken from 338 study participants and serum was tested for hepatitis B surface antigen (HBsAg) using Enzyme Linked ImmunoSorbent Assay. Results The overall prevalence of hepatitis B virus infection among pregnant women were 16 (4.7%) (95% CI 2.7, 7.7). Having a history of blood transfusion (AOR = 5.2; 95% CI 1.2–22.3), having a history of multiple sexual partners (AOR = 4.6; 95% CI 1.1–19.6) and having a history tonsillectomy (traditional surgical procedure) (AOR = 3.4; 95% CI 1.1–10.1) were the significant risk factors for hepatitis B virus infection.

Abstract
Background HBV vaccine is known to offer protection against transmission of HBV infection. Health care workers are mandated to have this vaccination as part of their occupational health safety measures. Post vaccination response data for HCWs in our setting is not available. This study therefore aimed to evaluate the anti-HBs titre levels after Hepatitis B vaccination among HCWs from selected heath facilities in the Cape Coast Metropolis, Ghana. Methods A multicenter (3 selected sites) analytical cross-sectional study involving 711 HCWs was conducted. Five (5mls) of blood samples were collected from each study participant and the serum used for HBV immunological profile testing anti-HBs quantification by ELISA test (Fortress Diagnostics Limited, Northern Ireland, United Kingdom). Data analyses were performed using Stata version 14.0 software (STATA Corp, Texas USA). Results The median age of participants was 29 years (IQR = 26–35 years). Majority (80.9%, n = 575) took their vaccination from Government health facilities compared with 19.1% (n = 136) from private vaccination sources. A total of 7 (3 males and 4 females) were found to be HBsAg positive giving prevalence of 1%. In all, 8.2% (n = 58) of the HCWs had anti-HBs titre levels <10IU/ml giving a sero-protection rate of 91.8%. HCWs who received 3 doses of HBV vaccine were more likely to be sero-protected as compared to those who received only one dose in multivariate analysis (aOR = 3.39, 95%CI: 1.08–10.67), p<0.037). Gender, cigarette smoking and alcohol consumption were not found to be associated with sero-protection. Conclusion There is a high HBV vaccine efficacy among HCWs in the Cape Coast Metropolis of Ghana with higher prevalence of anti-HBs titre level associated with full vaccine dose adherence. Post vaccination antibody titre determination could be an integral part of HBV vaccination protocol for HCWs in Ghana.
