Subtypes A, C, G, and recombinant HIV type 1 are circulating in Bangladesh.

We analyzed the genetic diversity of HIV-1 circulating in Bangladesh by direct sequencing and subsequent phylogenetic analysis of the V3 region of the env gene and p17 fragment of the gag gene from nine unrelated patients. The sequences from one sample grouped into subtype A, five samples grouped into subtype C, and one grouped into subtype G. In addition, two patients appeared to be infected with different recombinant viruses consisting of subtype A and unclassifiable viral sequences.
