AIDS
(acquired immunodeficiency syndrome) AIDS is
the name given to the late stages of HIV (human
immunodeficiency virus) infection, a disease discovered
and discussed in 1981 in Los Angeles, California. By
1983 the retrovirus responsible for HIV was first
described, and since then millions of adults and children
worldwide have died from contracting the disease. It is
thought to have originated in central Africa from monkeys
or developed from contaminated vaccines used in
the world’s first mass immunization for polio.
