Gorillas have been found, for the first time, to be a source of HIV.Previous research had shown the HIV-1 strain, the main source of human infections, with 33m cases worldwide, originated from a virus in chimpanzees.
But researchers have now discovered an HIV infection in a Cameroonian woman which is clearly linked to a gorilla strain, Nature Medicine reports.

French doctors treating the 62-year-old Cameroonian woman who was living in Paris said they initially spotted some discrepancies in routine viral load tests.
Further analysis of the HIV strain she was infected with showed it was more closely related to SIV from gorillas than HIV from humans.
She is the only person known to be infected with the new strain but the researchers expect to find other cases.
Before moving to Paris, she had lived in a semi-urban area of Cameroon and had no contact with gorillas or bush meat, suggesting she caught the virus from someone else who was carrying the gorilla strain.
