1 Post graduate Trainee, 2 Associate Professor, 3 Assistant Professor Department of Community Medicine, Katihar Medical College, Katihar, Bihar, India, 854105 *Corresponding Author Dr Purnendu Kumar Singh Department of Community Medicine, Katihar Medical College, Katihar, Bihar, India, 854105 Email: purnendukumars@yahoo.com Abstract Background: Hepatitis B (HB) is a global Public Health Problem infecting nearly 2 billion people around the globe. Health care workers are at risk of acquiring HBV, HCV, and HIV infections via exposure to patient’s blood and body fluids. HBV infection is a recognized occupational hazard and non immune professionals are at risk of acquiring the infection from their work. Objectives: (1) To assess the level of HBV vaccination status among health care workers, (2) To assess the knowledge of health care workers regarding Hepatitis B infection and its transmission. Methodology: An institution based cross sectional study was conducted in January to June 2018 covered all health care workers of Katihar Medical College. A self administered questionnaire was used for data collection about vaccination status and knowledge regarding Hepatitis B infection. The data was analyzed using epi Info version 7 statistical software. Results: Overall 51.31% health care workers were found unvaccinated. The vaccination rate was higher among faculty members (90.91%) and Interns (67.07%). The major reason for poor vaccination among lab attendants and Group D workers was that they never thought about vaccination (85.84% & 88.66% respectively) followed by no need felt about HBV vaccination (89.38% & 92.54% respectively). There was poor knowledge about route and mode of transmission among lab attendants and Group D workers. 41.98% Group D workers said that hepatitis B is transmitted by faecal oral route and by insects (61.78%). Conclusions: This study showed that hepatitis B vaccination status is poor among health care workers due to poor knowledge about HBV. A critical level of awareness and vaccination coverage is essential to decrease the possibility of transmission and burden of disease.
