The origins of the human immunodeficiency viruses: an update
1Department of Basic Dental Science, Dental School, University of Wales College of Medicine, Cardiff.
Abstract:
In 1981 a new acquired immunodeficiency syndrome was first described. The disease has a 100% mortality rate and over 359,000 cases have been reported to the WHO from 162 countries. The WHO estimates that the cumulative global total of AIDS cases as of early 1991 is more than 1.5 million. The dental profession, in line with other health care professions, is involved with guiding rational efforts to stop transmission and with developing effective means of treatment and prevention. This paper reviews the nature of the virus, its possible origins, and the implications of such origins for treatment and prevention of the disease.
