Human Immunodeficiency Virus (HIV). HIV is associated with AIDS. This virus attacks and destroys certain white blood cells (T-helper lymphocytes) that are involved in the immune system. As the number of these cells is reduced, the ability of your body to fight off infections also decreases. This eventually results in death. Although there is no cure, early detection allows for treatment with anti-viral therapies that can help to prolong life.
Cause: Virus.
Symptom: The virus destroys white blood cells that fight off infections. As their numbers are decreased the ability to fight off even the simplest of infections is reduced. This may result in death.
Treatment: There is no cure. Early detection of the virus and early treatment with anti-viral medications can reduce infections and prolong life.
