La diversité génétique du VIH-1 et données actuelles en Algérie

Algeria, alike other North African countries, has low prevalence of HIV infection. A molecular epidemiological study carried out on HIV-1 isolates from Algerian patients, using sequencing method, revealed the presence of a great genetic diversity among the strains circulating in this country. Subtype B was the most frequent but other non-B subtypes were found: A, G and D as well as intersubtype recombinants such as CRF 02-AG and CRF 06-cpx. The presence of this viral heterogeneity, probably coming from sub-Saharan African countries, incites us to vigilance in the surveillance of this infection.
