HSB: HIV Surveillance in Bangladesh

Surveillance for human immunodeficiency virus (HIV) infection is conducted annually among population groups most vulnerable to HIV infection. The rate of HIV prevalence among injecting drug users in an urban area in central Bangladesh has increased significantly over the past three years to a level of 4% in 2002. Through 2002, in all other population groups sampled, HIV prevalence has remained <1%. The findings of this report suggest a trend in Bangladesh toward a concentrated HIV epidemic among injecting drug users.
