The Evolutionary Perspective Of Origination Of Hiv And Aids

Scientists could predict how many people could die in a period of time. Since 1966, way before Dugas become a sexually active, scientist trace the virus not only in US, but also in places such as Haiti and Africa. Scientists took samples of blood from 1959, 1960 and bodies from 1908 they found the HVI virus in those samples. Beatrice Hahn, a professor from University of Pennsylvania, help to search for a much earlier Patient Zero, by taking it to Africa, and turning back the clock on a series of virus mutations and pinpointing with a diverse viruses such as SIV (simian immune virus), AGM (African green monkey) among many more of cross-species spillover (term scientists use to describe a moment a virus in one specie passes to other spice) in a jungle in Cameroon. A virus hunter, Nathan Wolfe, professor in human biology in Stanford University, takes it back even farther to an intracellular investigation in monkeys, gorillas, and chimps. Concluding with an intense research in chimps in a different places of West Africa, with a data, samples of major groups of HIV, and viruses from chimps created a model of “chimp Patient zero” hundreds of thousands of years

Numerous species of monkey were infected with the Simian Immunodeficiency Virus (SIV) or Simian-Human Immunodeficiency Virus (SHIV). The macaques were the primary group of monkeys infected. “Macaques are physiologically and immunologically similar to humans so there is a significant advantage over rodents and other species. The pathogenic SIV infection of macaques can lead to a disease that is called “simian AIDS;” it is similar in many respects to the disease caused by HIV-1 in humans” (Evans and Silvestri). Using the macaques allows different treatments to occur on the experimental level that cannot be conducted in humans. The treatments have provided and continue to provide “essential information to reach a deeper understanding of the biology of HIV infection and AIDS” (Evans and Silvestri). Non-human primates are easier to use than humans do to the ability to control the timing, dose and route of the virus as well as collecting the samples from tissues that are difficult to collect from humans. Macaques can be infected by vaginal or rectal routes or by oral routes. Macaques have been used to test various “microbicides and vaccines for mucosal protection against HIV acquisition” (Evans and Silvestri). By using non-human primate models for studies of AIDS, many results have been

There are four main groups of HIV strains (M, N O and P), each with a slightly different genetic make-up. This supports the hunter theory because every time SIV passed from a chimpanzee to a human, it would have developed in a slightly different way within the human body, and produced a slightly different strain. This explains why there is more than one strain of HIV-1 The most studied strain of HIV is HIV-1 Group M, which is the strain that has spread throughout the world and is responsible for the vast majority of HIV infections today. (“origin of HIV & AIDS,”

It is believed that the first case of HIV/AIDs was first recorded somewhere in West Africa somewhere in the beginning of the twentieth century. Since then, it has spread across central Africa, undetected for a long time. But the question that has bewildered many, is how HIV spread in the first place. According to “Natural Transfer Theory”, HIV was spread to humans through chimpanzees. “Africans have been killing and eating monkey for at least fifty thousand years” (43). It was common for small African communities to hunt and eat chimpanzees. Chimpanzees were said to have “SIVs, simian immunodeficiency viruses that closely resembles HIV” (41). The virus is said to have spread to humans through these infected chimpanzees. The blood of these chimpanzees could have

To begin with, many scientists found that HIV is related to a similar virus found in chimpanzee after conducting many researched they believe the virus was passed down from monkey hunters to human. Moreover, the first known case of HIV was reported in 1920 in

According to (Avert.org) “In 1999, a strain of SIV (called SIVcpz) was found in a chimpanzee that was almost identical to HIV in humans.The researchers who discovered this connection concluded that it proved chimpanzees were the source of HIV-1, and that the virus had at some point crossed species from chimps to humans”

This paper breaks down and defines what SIV is, the different subfields involved, and which species they originate from. The zoonotic transmission of the SIV virus from these non-human primates is discussed as well. As a result of these transmissions, the human immunodeficiency virus is brought to life. In this paper, this virus and its journey throughout history will be explained. Also, HIV and the different subfields this virus can be classified in are discussed throughout the research. As well as the where this virus was contracted, about the time when, and how it was possible. Also, the modern day methods of contracting this virus are listed in detail throughout the paper. The process of contraction of HIV through zoonotic transmissions is elaborated. An estimate on just how many of these animal-to-human transmissions that happened leading to HIV/AIDS is given. Lastly, the causes of how this virus was spread globally are broken down and explained each step of the way. This paper uses scholarly journals as references from a few different sources, including: Proquest, Academic OneFile, and Google Scholar.

This book talks about how recent genetic evidence form new discoveries have traced the birth of AIDS to being rooted in the southeastern forests of Cameroon in Africa, where chimpanzees had a very similar strain of Human Immunodeficiency Virus in their blood. They carried this simian immunodeficiency virus for hundreds of years without creating any major, large-scale outbreak in humans. The birth origin story of HIV may have been happened sometime around 1880 to 1920. TImberg and Halperin discuss that the birth of HIV most likely occurred when a European hunter traveling in

As previously stated HIV is a lent virus that attacks the immune system. In comparison SIV (Simian Immunodeficiency Virus) attacks the immune system of monkeys. So the question is: Did HIV in fact come from monkeys? A strain of SIV (called SIVcpz) was found in a chimpanzee upon research in 1999. This strain can infect humans and also be passed on from chimpanzee to chimpanzee. In conclusion the most reasonable transferring theory is based off of hunting. The SIV was transferred to humans as a result of the chimps infected blood and them be eaten. Then the virus migrated and transformed in what we know today as

Molecular epidemiologic data suggest that HIV type 1 (HIV-1), the most common subtype of HIV that infects humans, has been derived from the simian immunodeficiency virus, called SIVcpz, of the Pan troglodytes troglodytes subspecies of chimpanzee. The lentivirus strain SIVcpz is highly homologous with HIV-1, and another form of simian immunodeficiency virus found in sooty mangabeys (SIVsm) has similarities as

Unlike the plague, the Human Immunodeficiency Virus is species specific and has puzzled many scientist about the possibility of overcoming its harsh implications. This mean that HIV can be found only within a particular species and, in this case, this virus tends to attack the human race. Many blame that the very existence of AIDS emerged from gay people or relations with animals, but it’s believed that transmission of this virus originated from a close derivative of HIV, SIV. SIV in known as Simian Immunodeficiency Virus which the Monkey virus that is equivalent to HIV. It has been known that the development of AIDS started with the transmission of SIV to humans via being bitten by a primates or the consumption of a primate who is infected

Many people think that the origin of HIV, the AIDS virus, procures from natural evolutionary event. But, there is a theory called “cut hunter theory” in which a human, allegedly, African native, be given a infected splash while fighting with a chimpanzee carrying a similar to HIV virus. Although, most recent research holds that the origin of HIV and AIDS could never have happened this way. Others says that AIDS started in 1980s in the united states of America, but this was just when people first became aware of AIDS and it was a new health

Recent researches demonstrate that HIV might have got over from apes to humans roughly in the late 1800’s. After the 19th century, HIV has gradually sprawled across Africa and then into other parts of the world. According to the CDC, HIV has discovered in the US in the early 1980s (CDC, 2015). Generally, acute infection, clinical latency and finally AIDS are the three major stages of HIV. High fever, rash and sore

Beginning in the early 20th century in Africa, a retrovirus known as the Human Immunodeficiency Virus (HIV) presented itself; characterized by an attack on the hosts’ immune system

Curbing the spread of HIV has been a major goal since its emergence of the disease in 1981 in the sub Saharan Africa (http://www.unaids.org) . There are two viral strains that cause Acquired immunodeficiency syndrome (AIDS) in humans, human immunodeficiency viruses types 1 and 2 (HIV-1 and HIV-2). They have both resulted from the multiple cross species transmission of simian immunodeficiency virus that infects primates
