Content Summary :
HIV infection is caused by the Human Immunodeficiency Virus (HIV). The virus attacks the immune system, gradually breaking it down and making the body more likely to get infections and certain cancers. When the virus has significantly damaged the immune system, certain conditions typically occur. At this advanced stage, the HIV-infected person is said to have Acquired Immunodeficiency Syndrome (AIDS). HIV attacks the body by killing CD4 cells. Also known as “T-helper” cells, these help coordinate the immune responses that help fight off infections and other diseases. By doing this, HIV makes the patient more likely to get “opportunistic infections,” which usually do not make healthy people sick. Opportunistic infections cause disease only in people with very weakened immune systems and include Pneumocystis pneumonia, ophthalmic CMV infections, toxoplasmic encephalitis, Kaposi’s sarcoma and others. The presence of one of these opportunistic infections in patients with HIV virus means the person has AIDS. In addition to infection, patients with AIDS can develop other conditions, including HIV dementia (a type of senility), various cancers and weakness and weight loss.
