Sero-epidemiological study of hepatitis B virus infection in a village.

ABSTRACT

A cross-sectional study was conducted in a randomly selected village of Rangpur district from June '94 to May '95. Serum from 1000 human subjects irrespective of age and sex were screened for hepatitis B surface antigen (HBsAg). Among the respondents 661 were male and 339 female. The overall seroprevalence of HBsAg was 6.4%. It was 6.66% in male and 5.89% in female. Age, sex, religion, income, occupation, education and marital status did not show any relationship with HBsAg status. Among 64 sero-positive cases, 16 (25%) had no history of exposure to known risk factors and 48 (75%) had one or more exposure to known risk factors (p < 0.05). This study did not depict the national scenario. Well designed studies with more sensitive serological methods are recommended to get the epidemiological information of hepatitis B virus (HBV) infection in our community.
