HIV Adapting to Human Hosts
(Ivanhoe Newswire) – The HIV virus is adapting over time to its human hosts, according to a recently published study.
Researchers characterized HIV sequences from patients dating from 1979 to now, to assess the spread of immune escape mutations in the population. The results showed the virus is adapting slowly in North America, but in parts of the world harder hit by HIV, adaptation rates could be higher.
“We already have the tools to curb HIV in the form of treatment – and, we continue to advance towards a vaccine and a cure,” lead author Zabrina Brumme from Simon Fraser University, was quoted as saying. “Together, we can stop HIV/AIDS before the virus subverts host immunity through population-level adaptation.”
