Chimpanzees in the wild can die of AIDS, study says

For the first time, scientists have shown that chimpanzees in the wild become sick and die from the simian version of AIDS.

The finding upsets a widely held scientific belief that chimpanzees, the closest relatives to humans, can get the simian AIDS virus but without harm.

It also suggests that an outbreak of AIDS is contributing to the declining chimpanzee population in Africa, said the leader of the research team, Dr. Beatrice Hahn of the University of Alabama at Birmingham.

She said that comparisons of the viruses that cause AIDS in chimpanzees and humans could lead to new insights into the responses of the immune systems in both species.

"Our findings allow us to look at HIV from a new angle, comparing and contrasting chimpanzee and human infections," Hahn said.
