The hiv screening

Human immunodeficiency virus is really a slowly - replicating retrovirus. It causes acquired immunodeficiency syndrome (AIDS) a condition in humans where progressive failure of the immune system allows life-threatening opportunistic infections and cancers to thrive. AIDS is the late stage of HIV infection, whenever a person's immune system is severely damaged and has difficulty fighting diseases and certain cancers. HIV tests are accustomed to detect the current presence of the human immunodeficiency virus (HIV), the virus that creates acquired immunodeficiency syndrome (AIDS), in serum, saliva or urine. Such tests inform you if you should be contaminated with HIV or not. Based on a tough estimate given by the World Health Organisation (WHO), at the time of 2000, inadequate blood screening had led to 1 million new HIV infections worldwide.

1 in 4 new HIV infections occurs in youth aged between 13-24 years, based on CDC.

You will find two types of HIV virus, the HIV-1 and the HIV-2. Unless noted otherwise, in the United States, the term "HIV" primarily refers to the HIV-1. HIV-2 infections are predominantly within Africa.

Both HIV-1 and HIV-2 works by infecting and lowering the degrees of the CD4+T cells, cells which are crucial to help the body fight diseases. When CD4+T cell numbers decline below a vital level, the body becomes progressively more vunerable to opportunistic infections. HIV-1 and HIV-2 seem to package their RNA differently. Tests indicate that HIV-1 is better in a position to mutate (HIV-1 infection progresses to AIDS faster than HIV-2 infection and is in charge of the majority of global infections).

hiv screening is spread through blood and genital fluids, including pre-seminal fluids and semen or breast milk. One may become contaminated with HIV by engaging in unprotected sex or other types of sexual behavior having an HIV-positive person, or by sharing needles, syringes or other injection equipment with someone who is contaminated with HIV.

It generally takes a little while to get accurate results from an HIV test. This is because the blood tests that you take aren't testing for the current presence of HIV itself in your blood but are instead testing for the antibodies that the human body creates in an endeavor to fight the virus. Many HIV-positive people are unaware they are contaminated with the virus.

The amount of time required for antibodies showing up on HIV tests is highly variable, as they could show up as early as two weeks or as late as six months. Through that period, you can test HIV negative even though you are contaminated with the virus. You can still catch HIV from someone who is in the window period. Since donors are unaware of their infections, donated blood and blood products utilized in medicine are routinely checked for the HIV virus.

Both you and your partner should get tested for HIV and know your status before making love for the initial time. Women that are pregnant ought to be positively tested during each pregnancy. If the mother is contaminated with HIV, care should be used of minimizing the possibility of passing the virus to the baby. Medicines are available today, which taken properly during pregnancy can surely lower the risk of passing the HIV virus to the baby.

The absolute most commonly used HIV test is really a blood test. Blood will first be tested using the ELISA (enzyme-linked immunosorbent assay) test. If antibodies to HIV are present in the serum, they might bind to these HIV antigens.

ELISA results are reported as a number. If ELISA test is positive, the outcome is going to be confirmed using the Western Blot test, which tests just for HIV antibodies. In the United States such ELISA results are not reported as'positives ', unless confirmed by a Western Blot test. Newer HIV tests can detect HIV antibodies in mouth fluids (not saliva), a scraping from the mouth or urine. In 2012, the FDA approved the initial "in-home" HIV test. It works on the mouth swab and show results in 30-40 minutes. Any positive test result ought to be confirmed by a lab using the Western Blot.

Following a negative sixth-month test, it is advised that individuals get one final check done six months later to confirm the results. If the results are still negative, it is almost sure anyone is not contaminated with HIV.

HIV is comparable to other viruses, such as for instance those who cause cold and flu, with one important difference - the body cannot remove HIV. That means. If you get HIV, you get it for LIFE.

Right now we are at a vital moment in the fight against HIV/AIDS.

AIDS was previously a death sentence, however now more than 8 million people are on life-saving treatment. By 2015, with the scale up of treatment and prevention for HIV, we could see the beginning of the conclusion of AIDS.
