Subgenotypes of HIV-1 circulation in Ho Chi Minh city

ABSTRACT

This study was done in 2004. Subgenotypes of HIV were determined by DNA sequencing technique at 3 gene regions of HIV-l envelope, protease and reverse transcriptase. Our results showed that the recombinant virus CRFOI AlE was still predominant (98%) in Ho Chi Minh city. A new recombinant form HIV-l of subtype B and CRFOIAIE was also detected. The presence of a new recombinant form of HIV-1 derived from two different subtypes warns that the HIV epidemic in this region is more and more complex with the immigration and co-infection with different genetic subtypes of HIV.
