[Viral etiologies of AIDS: facts and hypotheses]
Abstract:
All the epidemiological features suggest that the acquired immunodeficiency syndrome (AIDS) is caused by a single transmissible agent and surely a virus. First, cytomegalovirus, Epstein-Barr virus and hepatitis B virus have been proposed as possible etiological agents of AIDS. A direct link between ubiquitous viruses and the occurrence of the disease has been discarded. At present time, etiological researches provide evidence that retroviruses are the best candidates for the etiology of AIDS. These agents could be directly responsible of the profound suppression of the cell-mediated immunity observed in patients with AIDS. Two human retroviruses are now proposed: human T-cell leukemia virus (HTLV) or lymphadenopathy associated virus (LAV). Moreover simian AIDS (SAIDS) occurred spontaneously at several primate centers in USA; a retrovirus partially related to Mason Pfizer monkey virus appears to be the etiologic agent of SAIDS.
