First new HIV strain discovered in the past 19 years

First new HIV strain discovered in the past 19 years

PanARMENIAN.Net - For the first time in 19 years, a team of scientists has detected a new strain of HIV, CNN says.

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, according to Abbott Laboratories, which conducted the research along with the University of Missouri, Kansas City. The findings were published Wednesday, November 5 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.

"It can be a real challenge for diagnostic tests," Mary Rodgers, a co-author of the report and a principal scientist at Abbott, said. Her company tests more than 60% of the world's blood supply, she said, and they have to look for new strains and track those in circulation so "we can accurately detect it, no matter where it happens to be in the world."

Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, said current treatments for HIV are effective against this strain and others. However, identifying a new strain provides a more complete map of how HIV evolves.
