This article deals with HIV AIDS Description. HIV works by weakening the body’s immune defenses by destroying the CD4 cells whichever the description. CD4 cells are a group of white blood cells that normally guard the body against all diseases and all infections. When HIV destroys CD4 cells, the body becomes very vulnerable to many infections. These infections are called opportunistic infections. Business Training in Kenya has more articles.
History of HIV AIDS in HIV AIDS Description
HIV/AIDS was first recognized as a new illness in 1981. Scientists have learned that the virus is spread through contact with an infected person’s body fluids; blood, semen and vaginal fluids. Once inside the body, HIV invades CD4 cells and uses the cells’ own genetic material to produce new HIV particles. These new particles make the infected CD4 cell to burst. The new particles then enter the bloodstream and infect other cells decreasing one’s CD4 cells.
Eventually, the number of CD4 cells drops below the threshold level needed to defend the body and the person develops AIDS. Initially, doctors used to think that HIV was inactive between the initial infection and the diagnosis of AIDS. But HIV is active, copying itself and killing CD4 cells from the time the infection starts through to the diagnosis of AIDS and even beyond.
Within the past two decades, around 60 million people worldwide have been infected with HIV and more than twenty million have since died. Ninety percent of these people live in developing countries. In parts of Africa, more than half the adult deaths are caused by HIV infection, leaving millions of children orphaned of AIDS. In the United States, as at the end of 2002, there were more than 886,000 cases of AIDS infections reported, with almost 500,000 deaths, including 5,315 children. HIV rates are increasing most rapidly among the minority populations. The infection rate is six times as often in African-Americans and three times as often in Hispanics compared with the whites.
Symptoms of HIV AIDS in HIV AIDS Description
In its early stages, the HIV infection has no symptoms or causes only a flu-like illness with much of fever, sore throat, rashes, nausea and vomiting, diarrhea, fatigue, swollen lymph nodes, muscle aches, headaches and joint pain. fifty percent to ninety percent of the people experience the symptoms within the first few weeks of contracting HIV but most of the people and the doctors dismiss the illness as a routine cold or flu. In a small number of cases, this early stage of infection may progress to inflammation of membranes covering the brain or other severe flu like symptoms that require one to go for hospitalization.
Diagnosis of HIV AIDS
Your doctor will probably ask about possible HIV risk factors, such as previous sexual partners, intravenous drug use, blood transfusion and the occupational exposure to blood, symptoms, such as fever, weight loss, muscle and joint aches, fatigue and headache, and about medical problems you may have had, such as skin rashes or infections, sinusitis, pneumonia and yeast infections. This typically is followed by a complete physical examination. He may also look for a thick, white coating on your tongue that may be thrush which is an infection with Candida fungus, skin abnormalities such as Kaposi’s sarcoma or recurrent infections and other abnormalities that suggest the diagnosis of AIDS.
HIV testing can be done in the hospital or in an anonymous clinic. The doctor will then confirm the diagnosis of HIV infection through blood tests. The initial screening test that is done is called the enzyme linked immunosorbent assay (ELISA) which detects disease-fighting proteins in your immune system antibodies specific to HIV. A Western blot test is also done. This measures the body’s response to HIV, it is done to confirm the diagnosis. Neither the ELISA nor Western blot is accurate immediately after an exposure to HIV virus. It can take a few months or weeks (window period) for these tests to become positive. After becoming positive, HIV RNA blood test is done to measure the amount of HIV virus in the blood i.e the viral load. Finally a CD4 count test is then done and if below two hundred then one is diagnosed with AIDS. HIV is a lifelong illness and infection
Prevention of HIV AIDS
One should avoid unprotected sexual intercourse, oral sex with an infected person, artificial insemination with infected semen, needle sharing, and contaminated blood transfusion and organ transplants from an infected donor. Pregnant infected mother should go for prenatal care to avoid infecting their newborns
Treatment of HIV AIDS
Your doctor should choose a combination of drugs to fight HIV infection. These drugs are called antiretroviral therapy drugs. Using several drugs simultaneously, helps to increase the effectiveness of AIDS treatment by attacking HIV virus at multiple points. Combining the drugs also limits the risk that HIV will become resistant to drugs
Another common treatment approach is highly active antiretroviral therapy (HAART), which combines three nucleoside analogues, two nucleoside analogues and one protease inhibitor, or two nucleoside analogues and one
Call a doctor if you believe that you have been exposed to the body fluids of someone who has HIV or AIDS virus or infection or if you test yourself for HIV at home.
Prognosis of HIV AIDS
On average, HIV infection progresses to AIDS is ten to eleven years if the person does not use antiviral medication or monotherapy is used. However in about twenty percent of people with HIV infection, usually those with the highest viral load, AIDS develops sooner like five years after infection. Two percent of people develop it later like more than twelve years after infection.
Once HIV infection has progressed to AIDS, there is an increased risk of death that varies from one the person to the other.
Conclusion on HIV AIDS Description
HIV AIDS is real and whichever description one gives to it they should try and avoid infection. HIV is a lifelong infection and one should not play around with it. HIV has claimed quite a number of lives and is still claiming more the safest way through therefore is to practice safe sex or abstinence.And thus HIV AIDS Description
