INFECTION OF A LABORATORY WORKER WITH SIMIAN IMMUNODEFICIENCY VIRUS

Simian immunodeficiency viruses (SIVs) are primate lentiviruses that are morphologically similar and biologically related to human immunodeficiency viruses (HIVs)1–4. SIVs naturally infect some nonhuman primate species, such as African green monkeys and sooty mangabey monkeys, without causing immunodeficiency. In contrast, experimental SIV infection of other susceptible primate species, such as macaques, can cause chronic wasting syndromes and a disease similar to the human acquired immunodeficiency syndrome (AIDS)5–10. Because of the similarities between the human and nonhuman lentiviruses, SIV and its susceptible primate host have become the principal model for studying the pathogenesis of AIDS and developing… © 1994, Massachusetts Medical Society.
