Acquired Immune Deficiency Syndrome Acquired Immune deficiency syndrome (AIDS)was first recognized as a disease in 1981 by the Center for Disease Control (CDC).AIDS leaves an individual vulnerable to illnesses that a healthy immune system would readily overcome.AIDS is acquired not inherited. The current epidemic of AIDS is predominantly among the homosexual male and intravenous (IV)drug users in the United States and the heterosexuals in central African population.The incidence of AIDS is increasing among other groups male and female.Never has so much been learned about a disease and its causative agent in such a short time but we have not solved the problem. reported to CDC that young homosexual men had a diseases ed pneuna by Pneunocystis carin.kaposi's sarcom.and various other oportunistic infections. The causative agent of AIDS is a retrovirus known as human immunodeficiency virus (HIV)which are envelope viruses and posses an RNA genome.The retroviruses use genome in an infected host.There are two antigenic ncy vi irus HIVI and HIV2.There is also simian immunodeficiency viruses (SIV)which is antigenically related and found in Primates in Africa.These viruses are in the family lentivirus family.

The incidence of AIDS is increasing among other groups male and female. Never has so much been learned about a disease and its causative agent in such a short time but we have not solved the problem. In the early 1980 it was reported to CDC that young homosexual men had a diseases that caused pneumonia by Pneumocystis carinii, Kaposi's sarcoma, and various other oportunistic infections. The causative agent of AIDS is a retrovirus known as human immunodeficiency virus (HIV) which are envelope viruses and posses an RNA genome. The retroviruses use reverse transcriptase to copy this genome in an infected host. There are two antigenic types of human immunodeficiency virus HIV1 and HIV2. There is also simian immunodeficiency viruses (SIV) which is antigenically related and found in Primates in Africa. These viruses are in the family lentivirus family.
