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

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.

Project description:BackgroundCoronavirus disease 19 (COVID-19) is currently a global health threat and public health emergency of international concern. Africa is the last continent to be hit by this pandemic and the population is still prone to misconceptions and may not take it seriously. In developing countries including Ethiopia, where trained human resources and equipment for the treatment of COVID-19 are scarce, working on prevention of the viral spread should be a priority as a feasible intervention strategy. The aim of this study was to determine the level of knowledge, attitude, practice (KAP) towards COVID-19 and its prevalence among hospital visitors.MethodsHealth institution based cross sectional study was conducted among 513 hospital visitors who are recruited by using simple random sampling technique at Ataye district hospital, Northeast Ethiopia from June 3, 2020 to August 10, 2020. A pre-tested structured questionnaire was used to obtain information related to socio-demographic characteristics, knowledge (11 questions), attitude (9 questions) and practice (9 questions). Oro-pharyngeal specimen was collected by trained healthcare provider and processed in a molecular laboratory. After extraction of viral nucleic acid, the Real-time fluorescent polymerase chain reaction (RT-PCR) kit was used for detecting novel coronavirus (2019-nCoV). Data was analyzed using bi-variable and multivariable logistic regression model with 95% CI (confidence interval). From the bi-variable analysis, variables having a P-value <0.25 were retained into multivariable analysis. From the multivariable analysis, variables with a P-value <0.05 was declared as associated factors.ResultsMajority (72.9%) of the study participants were male; and most were urban dwellers. From the total study participants, 17 (3.3%) were found to be infected with the virus. The magnitude of low-level of knowledge was 4.9%; and of the analyzed risk factors, female gender, age (category less than 16 years and category between 16 and 65 years), and usual alcohol drinking habit had statistically significant association with low level knowledge. The proportion of study participants who had low level of practice was 75/513 (14.62%). Family size, age category between 16 and 65 years, and low-level knowledge were associated with low-level practice.ConclusionLimited number of study participants had high-level knowledge and practice towards COVID-19; while majority of the study candidates demonstrated moderate level of knowledge and practice. Good knowledge, positive attitude and good practice can be a guarantee for the prevention and control of COVID-19. Hence, various measurements to combat the pandemic should be taken by different stakeholders including the community members, religious leader, health professionals and others.

Project description:Background:World Health Organization and Centers for Disease Control and Prevention recommend all health professionals to get vaccinated against hepatitis B virus before they start the clinical attachments during their stay in the medical school. However, only 18-39% of healthcare workers in low- and middle-income countries received the vaccine. Therefore, this study aims to determine the attitude and vaccination status of health professionals working at Adama General Hospital and Medical College. Methods:An institution-based cross-sectional study was conducted from December 2016 to February 2017 with 403 health professionals working at Adama General Hospital and Medical College. Data were collected using self-administered questionnaire distributed at the participant's work unit and analyzed using SPSS version 20. Multiple logistic regression analysis was conducted to identify factors that affect the complete vaccination status and p value < 0.05 was considered statistically significant. Result:The prevalence of complete vaccination against hepatitis B virus was 25.6%. The most frequently mentioned reasons for not being vaccinated were high cost of the vaccine (41%) and unavailability of the vaccine (36%). More than three-fourths (77.8%) of study participants strongly agreed that hepatitis B is a major public health threat and there was tendency among participants to believe that their profession will put them at increased risk of acquiring the disease (strongly agreed: 75.9%). Attending infection-prevention training [AOR = 2.3; 95% CI, 1.24-6.31], history of exposure to risky behavior [AOR = 5.5; 95% CI, 2.86-9.29], and long years of work experience [AOR = 3.1; 95% CI, 1.98-5.24] were statistically significant with complete vaccination status. Conclusion:Only one-quarter of health professionals received the recommended full dose of the vaccine. Sustained hepatitis B vaccination programs for healthcare workers need to be established by collaboration of different stakeholders to optimize health professionals' safety against this contagious infection.

Project description:Introduction: The coronavirus disease 2019 (COVID-19) pandemic continues to challenge healthcare services worldwide. Healthcare workers (HCWs) are key to the continued effort to overcome the pandemic. This study aims to evaluate the knowledge, attitude, and practices of HCWs toward COVID-19 in primary health centers in Dubai. Methods: This cross-sectional study was conducted at four primary health centers in Dubai, including two fever clinics, from July 5th to July 11th, 2020. A self-administered online questionnaire was distributed to nurses and physicians working in these centers, which evaluated their knowledge, attitude, and practices regarding COVID-19 and their associations with the participants' demographic factors. A total score of 80% and above constituted a level of sufficiency in each section. Additionally, Mann-Whitney U test and multivariable logistic regression were used to analyze the variables. Results: A total of 176 HCWs completed the questionnaire, with a 91.2% (176/193) response rate. They were predominantly female (158/176, 90.0%), nurses (128/176, 72.7%), and non-Emiratis (150/176, 85.2%). While official health organizations were the primary source of information for 91.5% (161/176) of participants, only 38.1% (67/176) reported using scientific journals as one of their sources. Overall, 57.4% (101/176) of participants had a sufficient overall level of knowledge. Moreover, knowledge regarding signs, symptoms, and at-risk groups was generally satisfactory. However, knowledge about the virus, testing, transmission, and the isolation of contacts with positive cases was identified correctly by less than two-thirds of the participants. Half of the participants (89/176, 50.6%) expressed their concern about personally acquiring the infection, 112/176 (63.6%) worried about their relatives acquiring it, and 72/176 (40.9%) expressed some hesitancy to take the COVID-19 vaccine once available. Overall, only 58/176 (33.0%) HCWs had a sufficient overall positive attitude score. Nurses, compared to physicians, and non-Emiratis compared to Emiratis' HCWs, had statistically higher mean scores for attitude (U = 2,212, p < 0.01; and U = 1164.5, p < 0.01, respectively). The majority of participants (156/176, 88.6%) reported acceptable infection control practices. Conclusion: Given the gaps identified in the knowledge and attitude, we recommend further training to improve the skills of primary HCWs, with encouragement to practice evidence-based medicine. Additionally, further exploration regarding vaccine hesitancy is warranted.

Project description:BackgroundHepatitis B virus (HBV) is considered highly prevalent in West Africa. However, major gaps in surveillance exist in Sierra Leone. Although healthcare workers (HCWs) are at high risk for HBV infection, little is known about the prevalence and knowledge of hepatitis B among HCWs in Sierra Leone.MethodsA cross-sectional study of all HCWs at the No. 34 Military Hospital located in Freetown, Sierra Leone, was conducted from March 20 to April 10, 2017. Whole blood was collected and screened for HBV markers using a one-step rapid immunochromatographic test with positive samples tested for HBV DNA. Additionally, questionnaires assessing self-reported knowledge of HBV infections were administered to all participants. Data were processed and analyzed using SPSS (version 17.0) software.ResultsA total of 211 HCWs were included in this study with a median age of 39.0 years (range: 18-59). Of the participating HCWs, 172 (81.5%) participants were susceptible (all markers negative), 21(10.0%) were current HBV (HBsAg positive) and nine (4.3%) were considered immune because of past infection (HBsAg negative and anti-HBc positive; anti-HBs positive). Additionally, nine (4.3%) participants displayed immunity to the virus as a result of prior hepatitis B vaccination (only anti-HBs positive). Of the 21 HCWs with positive HBsAg, 13 (61.9%) had detectable HBV DNA. There was a significantly lower risk for current HBV infection among HCWs older than 39 years (OR 0.337, p?=?0.046). In addition, only 14 (6.6%), 73 (34.6%) and 82 (38.9%) participants in this survey had adequate knowledge about the clinical outcome, routes of transmission, and correct preventive measures of HBV infection, respectively.ConclusionsHCWs in Sierra Leone lacked adequate knowledge of the hepatitis B virus. Additionally, the low coverage rate of hepatitis B vaccination among HCWs fails to meet WHO recommendations, leaving many of the sampled HCWs susceptible to infection. This study reaffirms the need for more intensive training for HCWs in addition to strengthening vaccination programmes to protect HCWs against HBV in Sierra Leone.
