AIDS and related diseases

This condition was first recognized in the United States in 1981.There was a huge number of patients with Pneumocystis carinii pneumonia recorded during that period. Center for Disease Control and Prevention (CDC) reported the unexplained occurrence of Pneumocystis carinii pneumonia in previously healthy adult males. Later they were found to be as homosexuals. There was a another set of previously healthy homosexual men developed Kaposi's sarcoma during the same period. Because of this unusual occurrence of above two conditions, health professional have done many investigations and they have found that above affected males were immunocompromised.
Human Immunodeficiency virus was isolated from a blood sample a patient with lymphadenopathy in 1983.The scientists were able to demonstrate that this virus was the causative agent of AIDS, exactly one year after its isolation .In 1985 they were able to develop an investigation to identify the virus. This investigation is known as Enzymelinked immunosorbent assay (ELISA).today this investigation is used as a screening test whereas the investigation called “western blot” is used as the confirmatory test.
Modes of transmission include unsafe sexual behaviors, transfusion of blood and blood products and vertical transmission ( from mother to fetus/baby).still nobody was able to find an effective treatment for this condition. Therefore best thing is the prevention.
