Acquired Immune Deficiency Syndrome (AIDS)

hiv blood infected system

A progressive, degenerative disease involving several major organ systems, including the immune system and central nervous system. Uniformly fatal, it is associated with human immunodeficiency virus (HIV), a viral infection that progressively weakens the immune system.

Since Acquired Immune Deficiency Syndrome (AIDS) manifests itself in a number of different diseases and conditions, it has been difficult to arrive at a formal definition. In an attempt to standardize the definition of AIDS, the Centers for Disease Control in 1992 included among its diagnostic criteria a count of 200 or fewer CD4T lymphocyte cells per cubic ml of blood (a sign of severe immune system suppression). AIDS was first recognized in 1981 as a cluster of symptoms in homosexual men in New York City and San Francisco. Eventually, similar symptoms were found among intravenous drug users, hemophiliacs, and other recipients of blood transfusions. In 1984, the human immunodeficiency virus (HIV) was isolated and subsequently determined as the probable cause of AIDS.

HIV is transmitted through sexual intercourse, contact with infected blood and blood products, and the birth process. However, casual social contact—even if close and prolonged—has not been found to spread HIV. The greatest number of HIV cases are sexually transmitted, through both homosexual and heterosexual intercourse. Screening of donated blood and blood products since 1985 has drastically reduced the risk of transfusion-related HIV. Children may be infected in utero or by exposure to blood and vaginal secretions during childbirth. The child of an infected mother has a 25 to 35 percent chance of acquiring the virus.

Persons infected with HIV initially show no symptoms. Within three to six weeks after infection they may exhibit flu-like symptoms that last up to three weeks and resolve spontaneously. According to long-term studies, all or almost all persons infected with HIV eventually become ill with full-blown AIDS, although the incubation period varies from less than a year to as long as 15 years. AIDS is considered full-blown when the immune system is seriously suppressed. At this point, the patient becomes vulnerable to opportunistic infections and diseases that are able to attack because of reduced immune system defenses. These include candiasis, pneumocystis carinii pneumonia (PCP), herpes and other viral infections, toxoplasmosis, and tuberculosis. AIDS also weakens the body's defenses against carcinomas, and conditions such as lymphoma and Kaposi's sarcoma are common complications of the disease. AIDS also attacks the nervous system. Neurological disorders such as encephalitis and dementia occur in over two-thirds of AIDS patients. HIV/AIDS patients are also prone to blood abnormalities, respiratory infections, and gastrointestinal problems, including diarrhea, which is partly responsible for the weight loss that occurs in the course of the disease.

Comforting a person with AIDS or any other fatal illness is challenging for friends, family, and others around him. Isolation is one of the most difficult aspects of this disease, often resulting from misinformation and fear about how the disease is spread. There is no scientific evidence that AIDS is spread through casual contact, and there is no reason to avoid gestures of friendship and comfort, such as a personal visit, a hug, or holding the patient's hand.

According to the World Health Organization, an estimated five to ten million people worldwide are infected with HIV. The highest incidence of AIDS is in major cities in Asia, Africa, and the United States. In the United States alone, there are thought to be over one million infected with HIV, and over 250,000 cases of full-blown AIDS have been reported. AIDS has become a leading cause of death in men and women under the age of 45 and children under the age of five. Originally thought of as a "gay men's disease," in 1993 AIDS was the nation's fourth leading cause of death in women between the ages of 15 and 44.

HIV is usually diagnosed through a test called ELISA (enzyme-linked immunosorbent assay), which screens the blood for HIV antibodies. If the test is positive, a more specific test, the Western blot assay, is administered. Most patients will test positive for HIV one to three months after being infected, and 95 percent will test positive after five months. There is no effective vaccine against the HIV virus, and no known cure for AIDS, but antiviral drugs have been effective in slowing the progression of the disease, particularly the suppression of the immune system. One of the earliest of these medications to be effective was azidothymidine (AZT), which inhibits viral DNA polymerase.

The best method of containing the AIDS epidemic is education and prevention. Much of the anti-AIDS effort both in the United States and globally has been directed toward promoting safer sex practices, including abstinence (especially among young people) and the use of latex condoms, which greatly reduce the chance of infection. The threat of HIV among intravenous drug users has been addressed by programs offering education, rehabilitation, and the free dispension of sterile needles. Modification of sexual behavior among homosexuals has been successful in reducing the incidence of new HIV infections among the gay population. However, risk-related behavior is increasing among young homosexuals under the mistaken belief that the threat of AIDS applies mostly to older gay men. Risky sexual behavior has also remained widespread among heterosexual teenagers in the 1990s, especially among African-American and Hispanic males.

Buying alcohol at night in London has always seemed a daunting task, where to go – the black market off license located on that dimly lit street or head to that vastly overpriced night club that everyone is raving purely because it is open until the early hours of the morning!

Well thank fully, help is at hand – at last alcohol delivered on demand – lets keep that party alive!

Licensing laws were amended during 2005 and alcohol delivery companies like DrinksXpress have been offering alcohol delivery your very front door in areas such as London.

Late night alcohol delivery london is becoming as popular as pizza delivery these days with alcohol companies popping up all over London especially in recent years. There is a large choice of strong proof drinks available, with some companies offering large menus of different spirited drinks and others offer main stream brands such as Smirnoff vodka, Gordon's Gin & Jack Daniels.

Beers or rather lagers, as you would expect, include Fosters, Kronenbourg & Stella Artois. Most companies advertise that the beers are delivered ice cold and are offered for sale in 4 packs, 8, 12 and 24 packs.

Wine delivery is equally catered for with all companies offering 24 hour alcohol via a variety of reds, whites and rose wines. Others also offer Prosecco as a sparkling wine alternative and virtually all drinks delivery companies offer some sort of champagne delivery service. DrinksXpress offered a wide variety with 6 different champagnes including rose champagne.

Late night food delivery in recent years has boomed, with new delivery companies opening and existing food delivery companies expanding their opening hours by obtaining late night refreshment licenses in addition to their hot food licenses – undoubtedly 24 hour pizza delivery will end up being a front runner in the late night food delivery league; if there ever becomes one of course! It seems that alcohol delivery companies have gone one step further by combining 24 hour alcohol delivery with 24 hour pizza and late night food delivery.

It seems that most alcohol delivery companies have latched on to the convenience market very firmly, the concept appears to work. A quick inspection of delivery middlemen sites such as Hungryhouse and JustEat further confirms this. Most alcohol delivery companies seem to have a second string to their bow; cigarette delivery - London is a huge city with a vast population and this makes the smaller profits margins more viable.

My wife and I prefer to camp one or more times a month, so for your New Year's weekend the program to camp at John Prince Campgrounds. The campground is placed on the South end of John Prince Terrain park. The park is about five miles west of I-95 in Lake Worth Florida, and is owned and operated by Palm Beach County. We quiet pleased when we arrived to see that this campground was family oriented and has so much to feature.

On Oct. 3, Simon Fraser makes the trek across the border to be able to on SeattleU at Championship Field starting at 2:30 p.m.

Some of the reasons this particular case hit our family so hard are that Kari was the period of my woman. My daughter happens to be grown using a family and has made us grandparents. Kari's parents and family choosing a lump sum all that a lot of. My daughter drove those same streets, as do I pay money for. She ended up being to have met her friend in the McDonalds which frequent on a regular factor. She even might look like my daughter. Every time we saw a poster of Kari we looked upon how will be able to have been our little princess.

Money Models. This is a form of handicapping utilized in sports that are not high-scoring because buy soccer jersey. To illustrate, in money line bets, this is what would seem on the board: Chargers, -1.2 Rams +1.4. This means that in order to bet over the favored Chargers, you need bet $120 to win $100. However if you bet on the Rams, won by you $140 for every $100 you wager when they win.

Overall this set was just a waste of $20.00. The hockey aspect among the set sucked, and the soccer game would happen to fun in the event the goalie post was larger to accommodate the large ball. The whole thing was just designed absolutely. It could already been a heap load of fun, this was just done right.

This is probably the easiest theme to find ideas relating to. There are several different duck shaped cake pans that you will get. Small rubber ducks or rubber duck bath toys make easy cake or cupcake toppers.
