(b) 1983 History of HIV In 1981 AIDS was first recognized when US centre for disease control and prevention repoed the unexplain occurrences of P. jiroveci infection in five previously health homosexual male. They appear to have lost their immunocompetence. So the condition was given the name "Acquired immune deficiency syndrome" (AIDS). In 1983 Lue montognier and colleagues from pasteur institute, Paris isolated a retro virus from a West African patient with persistent generalized lymphadenopathy and called it lymphadenopathy associated virus (LAV). In 1984 Ader Gallo repoed isolation of a retrovirus from AIDS patient and called it human T-cell lymphotrophic virus III.
