Scientists have created a strain of the human AIDS virus able to infect and multiply in monkeys in a step toward testing future vaccines in monkeys before trying them in people, according to a new study.
This strain of HIV, the human immunodeficiency virus, was developed by altering a single gene in the human version to allow it to infect a type of monkey called a pig-tailed macaque, the researchers said on Monday.
The genetically engineered virus, once injected into this monkey, proliferates almost as much as it does in people, but the animal ultimately suppresses it and the virus does not make it sick, they said.
The strain is called simian-tropic HIV-1, or stHIV-1.
Researchers hope to be able to test possible new AIDS drugs and vaccines in monkeys before trying them in people.

The first documented HIV case occurred in 1959, in Africa. There are conflicting reports of earlier cases.

Yes, but who has seen it? Is it a hoax? Or maybe it is swamp gas.
I just mean why not be a sceptic here. I have not seen this 1959 case and I have not seen any evidence for it. So I will remain a sceptic.
