Abstract
A sero-survey to assess the prevalence of hepatitis B virus infection was carried out among the Nicobarese children attending different primary schools of Car Nicobar Island. A total of 1574 children were screened for different serological markers of infection. Overall, 44% of the children had evidence of HBV infection with 23% positive for HBsAg. The prevalence rates were found to increase linearly with age. The implications of these findings in relation to control of hepatitis B in the tribal population of these islands are discussed.
