Human immunodeficiency virus is actually a slowly – replicating retrovirus. It causes acquired immunodeficiency syndrome (AIDS) an ailment in humans in which progressive failure of the defense mechanisms allows life-threatening opportunistic infections and cancers to thrive. AIDS is the late stage of HIV infection, when a person’s immune system is severely damaged and has difficulty fighting diseases and certain cancers. HIV tests are employed to detect the presence of the human immunodeficiency virus (HIV), the virus which induces acquired immunodeficiency syndrome (AIDS), in serum, saliva or urine. Such ชุดตรวจ HIV รู้ผลทันที tell you if you are infected with HIV or not. In accordance with a rough estimate provided by the World Health Organisation (WHO), as of 2000, inadequate blood screening had ended in 1 million new HIV infections worldwide.
1 in 4 new HIV infections happens in youth aged between 13-24 years, based on CDC.
There are 2 kinds of HIV virus, the HIV-1 and also the HIV-2. Unless noted otherwise, in the usa, the word “HIV” primarily means the HIV-1. HIV-2 infections are predominantly found in Africa.
Both HIV-1 and HIV-2 operates by infecting and lowering the levels of the CD4 T cells, cells that are important to help the body fight diseases. When CD4 T cell numbers decline below a critical 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 much better capable of mutate (HIV-1 infection progresses to AIDS faster than HIV-2 infection and is responsible for almost all global infections).
HIV is spread through blood and genital fluids, including pre-seminal fluids and semen or breast milk. One can become contaminated with HIV by participating in unprotected love or other types of sexual behavior with the HIV-positive person, or by sharing needles, syringes or any other injection equipment with someone who is contaminated with HIV.
It generally takes a short while to obtain accurate comes from an HIV test. This is because the blood tests that you simply take usually are not testing for the actual existence of HIV itself inside your blood but are instead testing for your antibodies that your particular body creates in an attempt to fight the virus. Many HIV-positive folks are unaware they are contaminated with the virus.
The amount of time needed for antibodies to show high on HIV tests is very variable, as they can show up as soon as fourteen days or as late as six months. During that period, you can test HIV negative even although you are infected with the virus. You can still catch HIV from someone who is incorporated in the window period. Since donors are not aware of their infections, donated blood and blood products found in medicine are routinely checked for the HIV virus.
You and the partner should get tested for HIV and know your status before having love for the first time. Pregnant women should be positively tested during each pregnancy. In the event the mother is contaminated with HIV, care should be taken of minimizing the risk of passing the virus for the baby. Medicines can be found today, which taken properly while pregnant can surely lower the risk of passing the HIV virus to the baby.
The most frequently used HIV test is really a blood test. Blood will first be tested making use of the ELISA (enzyme-linked immunosorbent assay) test. If antibodies to HIV can be found in the serum, they may bind to these HIV antigens.
ELISA results are reported as being a number. If ELISA test is positive, the results is going to be confirmed utilizing the Western Blot test, which tests just for HIV antibodies. In america such ELISA results are not reported as ‘positives’, unless confirmed by way of a Western Blot test. Newer HIV tests can detect HIV antibodies in mouth fluids (not saliva), a scraping from inside the mouth or urine. In 2012, the FDA approved the initial “in-home” HIV test. It utilizes a mouth swab and show leads to 30-40 minutes. Any positive test result zzeauh be confirmed by way of a lab using the Western Blot.
After a negative sixth-month test, our recommendation is that individuals get one final check done half a year later to verify the outcomes. In the event the effects are still negative, it is actually almost certain that this person is not contaminated with HIV.
HIV is similar to other viruses, such as people who cause cold and flu, with one important difference – the body cannot get rid of HIV. That means. Should you get HIV, you receive it for a lifetime.
