HIV/AIDS
The most recent surveillance report through 2002 states that the estimated people diagnose with AIDS was 886,575, and the estimated number of deaths of people with AIDS was 501, 669. The deaths in North Carolina through December 2000 was 6,462 (HIV).These scary numbers keep growing year after year, and the public health officials found out that the only mean of prevention against HIV is education(Foster 116). According to centers of disease control, the best defense against HIV is knowledge. National campaigns are teaching the following: definitions, risk behaviors, infection stages, testing procedures, and treatment. These national campaigns are making a big change in our culture, and giving hope to infected people. HIV (human immunodeficiency virus) is the virus that causes AIDS. Viruses are parasites that need a host to live and reproduce. HIV belongs to a special group known as retrovirus; they possessed a special enzyme that inverts genetic information. In other words, retrovirus make sick what once was healthy. HIV uses the CD4+ cell as a host, which is a cell that works in combination with the human organs to prevent invasion by foreign substances and keep the body healthy. The virus invades th
Antiretroviral drugs which are designed to attack this stage of the HIV lifecycle are called fusion inhibitors. For example a person, cannot get HIV by doing the next: by working with someone infected; from sweat, saliva, clothes, water fountains, phones, toilets, sharing a meal; from insect bites or strings; donating blood after 1985; from a kiss unless he or she has gum problems that keep the gums bleeding, in this case is considered a direct blood contact (HIV). Symptomatic stage the infected body starts to develop symptoms, last approximately five years, and the CD4+ count is 500. Any direct contact with blood and body fluids is a risk; this is why one needs to consider the following: sharing needles, tattooing, intravenous drug use (IDU's), blood transfusion before 1985, unprotected sex (any kind of sex), sharing toothbrushes, sharing razors, breastfeeding. AIDS is a serious disease and only a qualified health professional can diagnose it. Fifth phase, translation occurs when the protein building blocks, which will go on to form the new HIV particle are assembled within the human cell. Today's scientists are using all the recourses to find a cure and eradicate the disease. 3 billion new HIV virions are produced every day in people who are not on HAART. As the body uses the CD4's to fight the invader, it keeps losing its defenses and once the body is too weak to fight, is what we call AIDS (Foster 1). AIDS (acquired immunodeficiency syndrome) is a blood-borne and sexually transmitted disease. Forth phase, transcription; the two strands of DNA divide and form a new strand of viral RNA, sometimes called messenger RNA. New drugs called integrase inhibitors, which impede this stage of HIV's lifecycle, are in the very early stages of development. The initial stage lasts one to three months, and is from the day a person puts himself on a risk behavior that could get him infected. Last phase, viral assembly is when the protein building blocks are then cut into smaller pieces by a viral enzyme called protease.
