For the first time in 19 years, a team of scientists has detected a new strain of HIV.
The strain is a part of the Group M version of HIV-1, the same family of virus subtypes to blame for the global HIV pandemic. The findings were published Wednesday in the Journal of Acquired Immune Deficiency Syndromes.
HIV has several different subtypes or strains, and like other viruses, it has the ability to change and mutate over time. This is the first new Group M HIV strain identified since guidelines for classifying subtypes were established in 2000. It is important to know what strains of the virus are circulating to ensure that tests used to detect the disease are effective.
A case report of a man in Toronto who became infected with a multi-drug-resistant strain of HIV despite apparently very consistent adherence to PrEP was presented at the CROI 2016 conference in Boston today.
Viruses related to the human immunodeficiency virus (HIV) have infected Old World monkeys as far back as 16 million years ago, according to a new study. The research provides insight into how monkeys evolved and adapted to the simian version of HIV, and why some viruses can jump from one species to another.
