Introduction In September 1991, the Centers for Disease Control reported that, since AIDS (Acquired Immune Deficiency Syndrome) was first diagnosed in 1981, 195,718 active cases have been reported in the United States, with 126,159 of these resulting in death. Health agencies estimate that as many as 1.5 million Americans are already infected with the HIV (AIDS‐causing) virus, and that as many as 250,000 to 300,000 active cases will occur in the US. The World Health Organization estimates that about 10 million people worldwide are now infected with the HIV virus.
