Acquired immunodeficiency syndrome (AIDS) caused
by the human immunodeficiency virus (HIV) is a threat
and can be termed as a curse upon the human race.The
physicians and scientists first noticed and recognized
thepresence of AIDS as an actual disease following an
increase in the incidence of rare opportunistic
infections and cancers among otherwise healthy
homosexual men 1.
The first case of an unknown syndrome was reported
in USA in 1981, characterized by a profound drop in
CD4+ T lymphocyte counts and subsequent immune
depression of patients. In those days, the disease was
called “Gay pest”, “Gay cancer” or Gay-related
immune
deficiency (GRID), due to its major incidence
among men having sex with men (MSM)2,3.Further
demonstration that heterosexual patients were equally
susceptible to infection led to its official definition
as Acquired Immunodeficiency Syndrome (AIDS)4.
