Scientists find new strain of HIV

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.

A researcher told the BBC that, though it was a new type of HIV, current drugs might still help combat its effects.

HIV originated from a similar virus in chimpanzees called Simian Immunodeficiency Virus (SIV).
