AIDS is caused by a virus called HIV, but where this virus came from is not known. However, as new facts are discovered about viruses like HIV, the question of where HIV first came from is becoming more complicated to answer.

Moreover, such questions are no longer relevant and do not help in our efforts to combat this epidemic. What is more important is the fact that HIV is present in all countries and we need to determine how best to prevent the further spread of this deadly virus.
