Screening for hepatitis B virus was based on serological markers. Alanine aminotransferase levels and CD4+ T-lymphocyte counts were compared between patients. The study showed that 9.2% were positive for hepatitis B surface antigen with significant differences between alanine aminotransferase levels of patients with and without hepatitis B virus. We recommend a national surveillance system to monitor control efforts.enAntiretroviral therapyArticle
