Aids is becoming so widespread The disease called aids is becoming very widespread in the United States. The question is why. In the following paragraphs the answers to this question will be answered. Aids is the final, life-threatening stage of infection with human immuondeficiency virus (HIV). Aids stands for Acquired immunodeficiency virus syndrome. The name refers to the fact that HIV severely damages the patient's disease fighting immune system. Cases of AIDS were first identified in 1981 in the United States, but researchers have traced cases to as early as 1959. HIV can be present in the body for two to twelve or more years without producing any notifying sign of illness. An infected person can transmit the virus to another person whether or not the symptoms are present . Infection with HIV appears to be lifelong in all who become infected. People infected with Hiv eventually develop symptoms that also may be caused by another, less serious conditions. Some symptoms include enlarged lymph glands, tiredness, fever, loss of weight, diarrhea, and night sweats. AIDS is caused by two viruses that belong to a group called retroviruses. The virus became known as HIV-1. In 1985, scientists in France identified another closely related virus that produces AIDS. This such virus became known as HIV-2 and occurs mainly just in Africa. The virus,HIV-1 is spread throughout the world . HIV infects certain white blood cells, including T-helper cells and macrophages, that play key roles in the functioning of the human immune system. The virus attaches to certain molecules found only on the surface of cells. When an AIDS virus enters one of these cells, the virus inserts its genes into the cell's reproductive system and uses to produce more HIV. The infection kills the CD-4 cell and spreads the AIDS viruses other CD-4 cells , where the process is repeated. The number one reason why aids is becoming so widespread is through sexual intercourse. The disease gets passed on from one person to another by having unprotected sex with someone who is HIV positive or already has the disease AIDS. In the United States, sexual transmission of HIV or AIDS has occurred mainly among homosexual and bisexual men. It is becoming more frequent among heterosexual men and men. HIV is transmitted through all forms of sexual intercourse. To prevent transmission of the AIDS virus, intimate sexual with anyone who is or might be infected with the AIDS virus must be avoided. Many doctors advise people who might be infected with HIV to use condoms during sexual intercourse. The most effective preventative strategies are to reform from all sexual intimacy or restrict sexual intimacy to one unaffected person . The next best reason for the AIDS virus becoming so widespread is from HIV of AIDS infected mother passing the disease to the fetus or baby. An infected pregnant women can transmit the AIDS virus to her fetus even if she has no symptoms. Previous studies have shown a 10 to 60 percent chance that an infected mother will pass HIV to her unborn fetus. If the fetus escapes "in utero" threat , it may acquire the infection during delivery. Many doctors now also think that an HIV, the virus which causes AIDS, mother can pass on the virus to her baby after birth by breast feeding. In the largest study of mother-to-child HIV transmission to date, Philippe Van de Perre at the AIDS Reference Laboratory in Kigali, Rwanda , demonstrates that women who test negative for AIDS at the time of delivery, but women who become infected, can later pass the virus on to there infants, probably by breast feeding. Van de Perre and a team of AIDS studied 212 pregnant women who tested negative for HIV when they gave birth. Within 3 to 18 months later, 16 of these women tested positive for HIV. At some point during the 18 month period, nine of the 16 infants tested positive to HIV, the virus that causes. Previous studies have suggested that infected newborns may initially test negative, and then test positive within the 3 months after birth. In some other cases, the study implicates breast feeding as the route of HIV transmission. If babies acquired the HIV virus in the womb or during the birth, these infants probably would have detectable amounts of HIV in there blood very early. Another way the AIDS virus is becoming widespread is through direct with infected blood. People who inject drugs into their bodies can be exposed to infected blood by sharing needles and syringes. Transfusion and transplant recipients and people with hemophilia may contract the HIV virus from the blood, blood components, tissues, or organs of infected donors. However, screening and testing of both donate
