How HIV spread

The HIV virus has been tracked down to what scientist believe is one of the earliest stages. From the information provided in the Radiolab audio the HIV/Aids originated when a chimp ate a two different animals that had a virus similar to HIV/ AIDS. The virus they had though would be able to survive inside the monkey but something amazing happened. Both viruses infected the same cell and made the cell make replicas of themselves but in the process the cell mixed up their order and created a new virus, a hybrid from those two previous viruses. This all happened around the 1903. Later that virus kept evolving and got into a chimp. This chimp had a HIV which was the closet to HIV from Cameroon in Africa. This chimp was probably hunted by a hunter and the blood of the chimp somehow got into the hunter through a cut that made him get the virus. He then most likely went into a more urban area had passed on the virus to other victims. The virus was then exported to the USA in the 1960s and was spread out by the "Patient Zero", a French Canadian man that had homosexual relationships with men to pass them the disease.

How HIV has Impacted our World

The HIV/AIDS have infected greatly Africa by having 22.9 people infected with the virus. In 2010 around 1.2 million people died from HIV and AIDS in sub-Saharan Africa and 1.9 million people became infected with HIV/ AIDS. Since the beginning of the epidemic 14.8 million children have lost one or both parents to HIV/AIDS. The way these kids become orphans is caused how greatly by the virus. Most of the time the ones that provide the house income become ill . Following that person is the sex partner and like that the children of Africa become orphans. These viruses have also decreased the life expanctansy to 54.4 years. The viruses have also affected the economy by making workers unable to take part in construction, public project, etc. This greatly slows down the growth of the country and make it harder to fight against the HIV and AIDS.

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.
