![]() ![]() Until 1996, HIV infection was fatal in the vast majority of infected individuals. Therefore, infection with HIV does not necessarily mean AIDS, but all patients with AIDS have HIV infection. Most patients who die from AIDS succumb to one or more OIs.ĪIDS denotes the later stages of the disease and is not diagnosed until the patient has developed a significant OI or the CD4 cell count in the bloodstream falls below 200 (normal is 500 to 1,000 cells per milliliter). And destruction of CD4 cells renders a patient vulnerable to unusual opportunistic infections (OIs) that are rarely seen in healthy humans. This massive viral replication leads to a progressive loss of CD4 cells over a period of several years to as long as a decade. In an untreated person, 10 billion to 100 billion new viruses are produced per day. CD4 cells are vital players in the regulation of immune responses to invading microorganisms. Specifically, HIV targets T helper cells (CD4 cells), leading to the eventual death of the cell. HIV is a unique human RNA virus, capable of infecting cells of the immune system. There are some predictions that HIV will not be controlled until the middle of the next century and that it may continue to devastate developing countries for the next 100 years. The World Health Organization (WHO) estimates that millions are infected with HIV worldwide and that it is the most devastating epidemic since the influenza pandemic of 1918. Recent research suggests the virus "jumped" to humans from a West African subspecies of chimpanzee (Pan troglodytes troglodytes) intermittently decades or even centuries ago. AIDS is caused by the human immunodeficiency virus (HIV) and is spread through the exchange of body fluids (sexual encounters, sharing needles, blood transfusions). The acquired immune deficiency syndrome (AIDS) was first recognized in the early 1980s.
