AIDS is caused by HIV, a virus which dies within minutes outside a living host cell, or strictly controlled laboratory conditions.Assalamu Alaikkum warahamatullahi wabarakatuhu,
Some sources say it is a rumour - http://www.straitstimes.com/BreakingNews/ANN/Story/STIStory_741380.html .
Scientifically, it cannot be true as well because HIV dies as soon as it is out of the body and it cannot survive when it hits air. (http://www.ehow.com/how-does_5138788_long-aids-virus-live-air.html)
