AIDS Virus The Human Immune Deficiency Virus (HIV), which causes acquired immune deficiency syndrome (AIDS), principally attacks T-4 lymphocyte, a vital part of the human immunology system. As a result, the body's ability to resist opportunistic viral, bacterial, fungal, protozoa l, and other infection is greatly weekend. Pneumatically Carina pneumonia is the leading causes of death among people with HIV infection but the incidence of certain times of cancers such as B-cell lymphomas and Kaposi's sarcoma is also increased. Neurological complications and dramatic weight loss,or wasting,are characteristic of AIDS, which is end stage HIV disease. HIV is transmitted sexually; through contact with contaminated blood, tissue or needles; and from mother to child during birth or breast feeding. full blown symptoms of AIDS may not develop for more than 10 years after infection.
T-lymphocyte infected with HIV is the causes of AIDS . By infecting CD4 T- lymphocytes , a type of white blood cell, HIV weakens the immune system and leaves the infected individual open to deadly infections. The viruses gain access to a T-lymphocyte by attaching to CD4 pr0teins on outer surface of the cell membrane.
