Several Forms Of The Aids Virus example essay topic

The purpose of this paper will be too show how AIDS is a serious disease in the world today. AIDS, (Acquired Immune Deficiency Syndrome) is a complicated illness, caused by a virus that is passed from person to person. "The disease was first recognized in 1980 among homosexual men and injection drug users in New York and California". Several years after it was recognized, AIDS has become a worldwide epidemic. "By 1995,477,900 Americans had developed the disease, of whom 295,500 had died, and worldwide more than 14 million people were believed to be infected". American researchers initially named the virus that causes AIDS the human T-lympho tropic virus, type -or HTLV- ("A.I.D.S".

). After researchers discovered in the late 1980's that there were several forms of the AIDS virus, the original virus was renamed the human immunodeficiency virus type 1, or HIV-1 ("A.I.D. S"). The virus enters the bloodstream and destroys certain white blood cells. The virus can infect other types of cells in the body, including the immune-system cells. AIDS is transmitted intimate contact between people or through blood transfer.

The virus is spread through sexual intercourse, the sharing of needles and syringes, or transfusion of blood products. Transfusion of blood from an HIV- Koroskoski 2 person is certain to cause in infection of the recipient. "Needle sharing involves transfusion of smaller amounts of blood but is still a means of spreading the virus; in areas where HIV is prevalent, such as in metropolitan areas of the eastern United States, active intravenous drug use in associated with HIV infections rates of around 50 percent."Sexual transmission, by semen or vaginal fluids either through vaginal or anal intercourse, to male or female partners is probably less efficient than direct blood transfusion". Other forms of sexual activity can also transmit the disease from person to person, but kissing on the lips appears to carry little risk of spreading HIV. There is still that slight risk of kissing, so you shouldn't think you couldn't get it.

The AIDS virus can be spread during pregnancy from mother to fetus, or to the newborn infant at the time of birth, or by breast-feeding. "About a fifth to a third of newborns of HIV-infected mothers in the United States acquire the virus from their mothers". When HIV first infects someone, there can be an acute onset of fever, rash, and meningitis ("A.I.D.S". ).

Later during the incubation period of AIDS, swollen lymph nodes commonly develop, reflecting activity of HIV in those tissues of the immune system ("A.I.D. S"). At this moment, there is no cure for this disease. There are several antiviral drugs that delay the spreading of the disease throughout the body. When you are HIV positive these drugs delay the process of the disease.

Some of the drugs Koroskoski 3 improve your survival risk. "In response to the worldwide epidemic a major research effort has been undertaken to find therapies to inhibit and eventually eradicate AIDS."At present, efforts to prevent further spread of AIDS focus on the dissemination of knowledge as to how the virus is spread and on convincing people to avoid exposure". Some communities have made programs to stop the sharing of needles for drug abuse. "The screening of donor blood for HIV-1 and other viruses since 1985 has virtually eliminated blood transfusion as a source of HIV infection in developed countries". Scientists have been working on a vaccine, but still haven't come up with one yet. Schools teach children about AIDS.

They teach them about safe sex. Condoms are useful from not only getting AIDS but other diseases as well. The purpose of this paper shows you how AIDS is a serious disease in the world today. It is spreading around the world. There is no vaccine yet and a lot of people are dying from AIDS. If you have sex you should at least use a condom.
