Although the initial belief was that transmission
of the disease, cause still unknown, was somehow re-
lated to homosexual behaviors, it soon became ap-
parent that other means of transmission were also
likely—most notably through contaminated blood.
By the end of 1982, at which time more than six
hundred cases had been reported, it was clear that
intravenous (IV) drug abusers were at risk; cases
were also observed in several hemophiliacs, whose
only possible exposure had been through their use
of Factor VIII (blood-clotting) products obtained
from donated blood. The name of the illness was
also changed, reflecting its more widespread nature,
to acquired immunodeficiency syndrome, or AIDS.
The range of opportunistic infections associated
with the immune disorder was also widened to in-
clude illnesses such as fungal and other rare para-
sitic infections.
If there was any fortunate aspect associated with
the outbreak at the time, it involved a growing under-
standing of the unknown etiological agent’s method
of transmission. While it clearly could be transmitted
through sexual behaviors, as well as in contaminated
blood, it was not transmitted through the air. Victims
were classified by the CDC as falling into four specific
categories, including homosexual or bisexual males
(75 percent of known victims), IV drug abusers (13
percent), and hemophiliacs or transfusion recipients
