Oxford Population Health news release

The largest-ever study mapping genetic variants of HIV-1 around the world over the past 35 years shows that the regional distribution of different subtypes of the virus continues to evolve, posing a challenge to prevention and treatment efforts.

Researchers studied data from nearly 1.4 million HIV-1 samples collected between 1990 and 2024 from 154 countries. These data were combined with UNAIDS estimates of the number of people living with HIV in each country to map the global distribution of HIV-1 subtypes and recombinant strains over time.
