How do monkeys have AIDS?

Answer:
Monkeys do not have AIDS. The syndrome affects only humans and is caused by the HIV virus.

It is now generally accepted that the virus HIV (Human Immunodeficiency Virus) is a descendant of a Simian Immunodeficiency Virus (SIV) that was found because certain strains of SIVs bear a very close resemblance to HIV.
