By the time the first reported cases of AIDS were found in large United States cities, the prevalence of HIV infection in some communities had passed 5%. [70]
This estimation was the result of time-scaled evolutionary models being applied to modern samples and retrieved early samples of HIV-1 (M). [ 6 ] [ 7 ] It had previously been estimated from the genetic differences between LEO70 and DRC60 samples and later samples that HIV-1 group M had jumped into humans in 1908 ± 10 years.

It is possible to end AIDS by 2030 if countries demonstrate the political will to invest in prevention and treatment and adopt non-discriminatory laws, the United Nations said on Thursday. In 2022 ...
