Opportunistic diseases as a consequence of HIV/AIDS

Abstract

Acquired Immuno Deficiency Syndrome is a major threatening disease occurring in humankind, caused by Human Immunodeficiency Virus. With the progression of HIV infection, the immune system of the infected gets weakened as the virus attacks immune system and impairs the function of immune cells. Hence several pathogens take the opportunity to invade the host. Present review focuses on the advancement of HIV and opportunistic illnesses caused by various pathogenic organisms. Opportunistic diseases do not often affect healthy individuals with potential immune system where as individuals with weakened immune system are highly affected. Inspite of various therapies used to treat AIDS; it may also lead to opportunistic infections. © 2011 Soumya D, et al.
