Extract

Acquired immunodeficiency syndrome continues to expand exponentially, although the rate of growth in some sectors of the population has been slowing. Unfortunately, these clinically manifest cases constitute only a tiny fraction of the population infected with the human immunodeficiency virus. Epidemiologic data provide only crude estimates of the prevalence of asymptomatic viral infection, although more specific information is available for certain groups, most often defined by demographic, behavioral and medical information. Those data suggest that the prevalence of virus varies some 5000-fold from as low as 0.01 percent up to 50 percent.

The extraordinary and relatively unmodifiable consequences of HIV infection provoke increasing concern among health care workers about the possibility of nosocomial infection. For nosocomial transmission to occur: 1) the patient must be infected; 2) parenteral exposure to blood or certain other body fluids must occur; and 3) the virus must be transferred (with the latter likelihood being proportional to the quantity of exposure).
