HIV strain ‘came from Haiti’
The Secret Origin of AIDS and HIV
The strain of the HIV virus which predominates in the United States and Europe has been traced back to Haiti by an international team of scientists.
The strain passed from Haiti to the US in about 1969 before spreading further, says the team in the Proceedings of the US National Academy of Sciences.
They hope knowing this could help find a cure for HIV, which can lead to Aids.
“HIV-1 group M subtype B” predominates in the US, Europe, large parts of South America, Australia and Japan.Now scientists say they know where it came from.
…
Michael Worobey of the University of Arizona in Tucson is one of the study’s authors. He says the new research suggests HIV first arrived in Haiti in the mid-1960s - probably from Africa where HIV is thought to have originated - before making its crossing into the US.
…
Prof Worobey and his colleagues now want to trace the strain back further. His suspicion is that it probably arrived in Haiti from the Congo via Haitians who were working in Africa during those years.He says understanding the origins of this and other strains of HIV will better enable scientists to predict how the virus may mutate in the future.
