AIDS, unlike most communicable disease, is transmitted only by exchange of body fluids through sexual contact, sharing of needles and syringes, or transfusion of infected blood. According to the U.S. Department of Health and Human Services, Public Health Service, no cases have been found where the AIDS virus has been transmitted by casual contact. As a result, there is no evidence that employing a person with AIDS would present a health hazard to other people in the work place.
