The immunization status and level of knowledge about hepatitis B virus infection among Nigerian surgeons.

Hepatitis B virus (HBV) infection is an occupational risk of surgeons especially in developing countries where asymptomatic carrier rate is about 15%. Despite better knowledge about mode of transmission and methods of prevention including use of active immunization, it still remains a threat. In this study, a questionnaire survey of Nigerian surgeons was conducted to ascertain their knowledge, and immunization status against HBV infection. Our study showed a 9.3% incidence of clinical HBV infection, poor perception of risk of infection, poor local availability of vaccines, and low uptake where same was available. Reasons cited for non-immunization are lack of awareness, cost, inertia and non-availability of vaccines. Only 10.2% of our respondents always used barrier methods, and 77.7% of our respondents do not check the immune status of their patients after sustaining an intraoperative sharp injury. The overall level of knowledge about HBV infection was deemed poor. We conclude with recommendations on how to improve knowledge about HBV infection and uptake of vaccines.
