AIDS and HIV
Aids-acquired immune deficiency syndrome- is caused by HIV (Human Immunodefiniency Virus), which produces no symptoms for up to ten years before a person is diagnosed with aids. This virus attacks the immune system and leaves the body vulnerable to a lot of life-threatening illnesses. Bacteria, yeast, and viruses that do not cause disease cause these illnesses. Aids has become the most serious worldwide epidemic, and one of most dangerous stage of HIV. AIDS was known in the early 1980s. A new study of the oldest known HIV suggests the virus jumped from animals to humans in the 1940s. (Goudsmit 2) The year was 1959, in the central African city of Leopoldville. A seeming healthy man walked in to a hospital clinic to give blood for a Western backed study of blood diseases. He walked away and was never heard from again. Doctors analyzed his sample, froze it in a test tube and forgot about it. A quarter-century later, in the mid-1980s, researchers studied the growing AIDS epidemic and took a second look at the blood and discovered that it contained HIV, the virus that causes AIDS. The Leopoldville sample is the oldest specimen of the aids virus ever isolated and may help solve the mystery of
„h Loss of appetite, indigestion, or other gastrointestinal upset One of the most common modes of transmission is by contact with infected blood. HIV is spread among injection drug user by the sharing of needles with minute quantities of blood of someone infected with the virus. Also, women can transmit HIV to their babies during pregnancy or birth. Since no vaccine for HIV is available, the only way to prevent infection by the virus is to avoid behaviors that put a person at risk of infection, such as sharing needles and having unprotected sex. Because many people infected with HIV have no symptoms, there is no way of knowing with certainty whether a sexual partner is infected unless he or she has been tested for the virus or has not engaged in any risky behavior. CDC recommends that people either abstain from sex or product themselves by using male latex condoms whenever having oral, anal or vaginal sex. Only male condoms made of latex should be used, and water-based lubricants should be used with latex condoms.
