But some people may not feel sick during this stage. Gallo said the similarity might be because "the individuals from whom these isolates were derived acquired the virus at a similar time and place," which made about as much sense as two students, saying that maybe their term papers were identical because they had studied together.

A collection of patient education fact sheets on HIV/AIDS treatments and conditions, in English and Spanish. Also, an extensive listing of AIDS-related internet web site addresses.
HIV (human immunodeficiency virus) is a virus that most likely mutated decades ago from a virus that infected chimpanzees to one that infects humans.
It began to spread beyond the African continent in the late s and is now endemic worldwide. HIV causes disease because it attacks critical immune defense cells and over time overwhelms the immune system.
