AIDS is a syndrome characterized by severe cellular immune deficiency. It is caused by the human immunodeficiency virus (HIV). HIV was first discovered in 1983 and is a retrovirus that can be transmitted sexually or through contact with infected blood or bodily fluids. Over time, HIV progresses through several phases, initially causing flu-like symptoms before entering asymptomatic and symptomatic phases marked by opportunistic infections. High-risk groups for HIV/AIDS include homosexual/bisexual men, infants born to infected mothers, intravenous drug users, and sexual partners of those infected. Diagnosis involves HIV antibody tests and examinations to assess immune system functioning.

immune suppressive drugs , which are well known infectious diseases and so on .
etiology of AIDS
The cause is a group of viruses called retro human immunodeficiency virus ( HIV ) . HIV was
first discovered in 1983 and known as retroviruses HIV – 1 . In 1986 in Africa again found a
new retrovirus called HIV – 2 . HIV – 2 is regarded as less pathogenic virus with HIV-1 . So to
facilitate both called HIV .
Transmission of HIV infection and AIDS consists of five phases:
Window period . The duration of 4 weeks to 6 months after infection . There are no symptoms .
Phase of acute primary HIV infection . The duration of 1-2 weeks with flu symptoms likes
illness .
Asymptomatic infection . The length of 1-15 or more years with no symptoms .
Symptomatic immune suppression . Over 3 years with symptoms of fever , night sweats , B
decreased , diarrhea , neuropathy , weakness , rash , lymphadenopathy , oral lesions .
AIDS . The length varies between 1-5 years of AIDS was first established conditions . Obtained
severe opportunistic infections and tumors in various body systems , and neurologic
manifestations .
AIDS can affect all age groups , including infants , men and women . Which includes high-risk
groups are :
1 . Homosexual or bisexual men .
2 . Infants of mothers / fathers are infected .
3 . People who intravenous drug
4 . Sexual partners of people with AIDS
5 . Recipients of blood or blood products ( transfusion ) .
Diagnostic examination
Test for the diagnosis of HIV infection :
ELISA
Western blot
P24 antigen test
HIV culture
Tests for the detection of disorders of the immune system .
Hematocrit .
LED
CD4 lymphocyte
CD4/CD lymphocyte ratio
