Researchers in Europe announced they have found a new strain of HIV, the virus that causes AIDS, in a woman from Cameroon.
The new virus, researchers say, appears to have originated in gorillas, unlike the other three subtypes of the virus which are believed to have evolved in chimpanzees, the BBC is reporting.
While the new strain is considered somewhat of a novelty, it could have serious implications, explains Professor Paul Sharp of the University of Edinburgh:
“The medical implication is that, because this virus is not very closely related to the other three HIV-1 groups, it is not detected by conventional tests. So the virus could be cryptically spreading in the population.”
Researchers believe the virus which is the forerunner of HIV is another virus called Simian Immunodeficiency Virus (SIV). They believe this new, gorilla evolved strain was likely transmitted from chimps to gorillas.
This news comes as researchers announced that SIV was killing chimps in Africa, something they previously thought did not happen.
