How HIV is Treated and Some Precautions
Now days scientist are trying to make a vaccine to fight of the viruses of HIV. Two main types of HIV vaccines are currently being tested are preventive and therapeutic. Preventative vaccines are meant for people that yet don't posses the virus and helps their immune system recognize the virus before it's too late. Therapeutic vaccines on the other hand are for people who have HIV to control,the infection and delay the progression. This method is based on limiting in how much the HIV can reproduce itself. Currently there isn't a vaccine. The reason why there isn't a vaccine yet is because HIV virus makes copies of itself very quickly. The virus is very fast at reproducing and is very clever. It can outwit the immune system. There are many types of HIV, this makes it even twice as hard for scientist to move forward. Out of all of the result none of the people that have been infected have gotten completely rid of the virus. For the moment all that scientist can do is keep observing and testing for a future vaccine.
There is some treatment for HIV to fight against them but this comes with a risk of side effects many of these side affects are Fatigue, Anemia, Diarrhea, nausea, and more. The most common tests used to diagnose HIV involve looking for HIV antibodies in blood. It takes about six weeks for the antibodies to form. When the possibility of acute or early HIV infection is being considered and immediate treatment is needed, tests that can detect both HIV antigens, a protein produced by the virus immediately after infection, and HIV antibodies are used. There is now a rapid test available that identifies both antibodies and antigens within 2 to 4 weeks of being infected. Tests are also available to measure the HIV virus load by looking at HIV RNA. Post-exposure prophylaxis (PEP) is one of the medicines to fight HIV. It involves taking HIV medicines as soon as possible after exposure to HIV to reduce the risk of HIV infection. HIV-infected women take HIV medicines during pregnancy and childbirth to reduce the risk of mother-to-child transmission of HIV. To further reduce the risk, their newborn babies also receive HIV medicine for six weeks after birth. Mothers are also told not to breast feed their children. Basic ways to prevent HIV from spreading is by suing condoms, have the least number of sex partners, having the least sex possible with strangers, asking your partner to take an HIV test before sex and by not sharing needles if taking drugs.
