"Prior to this it was thought that when African apes and monkeys were infected with SIV, there was no clinical disease." For nearly a decade, researchers have closely observed three free-living chimpanzee communities at the Gombe National Park in Tanzania -- home to the legendary work of primatologist Jane Goodall. More than 40 different SIVs naturally occur in dozens of African primate species, but they were universally believed to be virtually harmless.
