Contact tracing in the acquired immune deficiency syndrome (AIDS): Evidence for transmission of virus and disease by an asymptomatic carrier

Abstract
The sexual contacts of a patient with acquired immune deficiency syndrome [AIDS] were traced; clinical, immunological and serological evidence was obtained and evaluated. The patient apparently acquired the disease from a homosexual man who had no symptoms, but in whom laboratory evidence of immunodeficiency and serological evidence of exposure to the AIDS-associated retrovirus was found.
