Multi-national scientists found that HIV-4, both from Cameroon’s chimpanzees and gorillas, is the first human being to fully identify all the sources of HIV.
There are currently four known HIV, M, N, O and P, each of which has its own source. Among them, the most widely spread M and N have been confirmed from chimpanzees, but rarer and P Has not been able to confirm the source.
By analyzing the genetic data of chimpanzees and gorillas in Cameroon and its neighboring areas, the results finally confirmed that both ö and P are gorillas from southwestern Cameroon.
There are only two P-type cases so far in the world, and the O-type is only 100,000. It is mainly concentrated in Central and West Africa.
