Abstract
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.

There have been 4,043 reported diagnosed cases of Human Immunodeficiency Virus infection (HIV) per 100,000 populations. Human Immunodeficiency Virus is a virus that attacks the body’s immune system. The Human Immunodeficiency Virus attacks a specific white blood cell called T- helper cells which are used to fight off infection. As the virus destroys the t- helper cells, it replicates, destroying the immune system of the individual. Individuals who have the Human Immunodeficiency Virus Infection will have to constantly take medication to suppress the spread of the disease. If left untreated it will become very difficult for the individual’s body to fight off the virus resulting in death.
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
HIV is responsible for 25 million deaths and 65 million infections worldwide. Both The Untied states and Russia have high rates of infected and related deaths do to HIV. 2.1 million people in The United states are living with the HIV infection and 1in 5 are unaware of their infection. Approximately
The term Human Immunodeficiency Virus is commonly known as (HIV), which is a virus that attacks the immune system of humans by destroying the amount of CD4 cells in their bodies. Without CD4 the human body is unable to fight against diseases, which can lead to Acquired Immune deficiency syndrome known as AIDS for short. The first case of the HIV/AIDS virus in the U.S. occurred in the early 1980’s. The first spark of the virus was found in San Francisco with couple of homosexual Caucasian American males. Today African Americans account for the largest proportion of HIV and AIDS in this country, represent approximately 13% of the U.S. population, but accounted for an estimated 44% of new HIV infections in 2010(the last year a study was
36.7 million People were recorded to have HIV in 2015(WHO). 39 million people have died from HIV and AIDS as of 2015 and HIV is classed as pandemic issues as it affects people worldwide (WHO). HIV is a virus that attacks the immune system by doing this it weakens your systems and reduces the chance of you fighting off infections and diseases. Most commonly spread through having unprotected sex, mother to child and through sharps such as needles (blood). AIDS is a disease which is the last stage of HIV (Gallo 1984).
HIV stands for human immunodeficiency virus. It can lead to immunodeficiency syndrome or AIDS. It is caused by the HIV entering the uninfected body and stats to destroy CD4+cells which are there to help the body fight infection and disease (Webmd.com, 2014). Once you have HIV, you have it for life. More than 1.1 million people in United States alone are living with HIV and 1 out of 6 font even know it. About 50,000 people are infected with HIV each year (Cdc.gov, 2014). It is more commonly see in the gay community particularly young black males. In 2011 an estimated that 15,529 people had died. (Aids.gov, 2014)
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
HIV is a universal and a pandemic disease has claimed 33 million lives globally in the 1980s. It is approximated that 35 million
HIV is a quite detrimental virus that has caused much disruption during the 1980’s when it came to life. HIV is “one of the fastest evolving of all organisms” (Rambaut A. ET. Al. 2004) HIV has found ways in which to resist drugs and shows evolutionary mechanisms. The HIV virus has also
HIV/AIDS is a health issue that has affected the lives of 35 million individuals globally and has continued to spread due to social conditions which surround us. Risky behaviors such as men having sex with men, large number of homeless population, large number of African American men incarcerated, and injection of drugs also attribute to the large number cases of HIV/AIDS.
Human Immunodeficiency Virus (HIV) the precursor to Acquired Immune Deficiency Syndrome (AIDS) is prevalent in the United States. The October 2008 Center for Disease Control (CDC) Morbidity
AIDS (Acquired immunodeficiency syndrome) is disease caused HIV (human immunodeficiency viruses). This research paper describes the evolution and origination of HIV and AIDS. There are two types of HIVs. These are called HIV-1 and HIV-2. HIVs result multiple cross species transmission from SIV (simian immunodeficiency viruses) that is viruses that infects primates. HIV-1 comes from SIV from chimpanzees whereas HIV-2 comes from sooty mangabeys. HIV-1 has four sub groups these includes M, N, O, and P. Each of groups has resulted from independent cross-species transmission event. Group M is the most virulent, and it is the first to be discovered. HIV-2 has groups that ranges from A to H. SIV are infecting West Africa primates. This fact is based on the first pandemic HIV-1 has emerged in colonial West African, and most researchers have sampled primates from this region only. Newly emerged SIVs are resulted from multiple cross species transmission and recombination. The cross species transmission occurs from non-humans to humans through eating bushmeat. The cross transmission influenced by host restriction factors, but HIVs were able to pass this barriers. Most SIV are non-pathogenic to the host; however, there is some evidence that some are pathogenic to their host. The age of the virus determined by using molecular clock method. Other studies have estimated the evolutionary timescale with same age as
This history of HIV/AIDS as a blurry timeline before the 1980’s since that was around the time reports came in which eventually become an HIV report. The origin of HIV can be traced back to the early part of the century. Some believe that in the 1920’s chimpanzees from the Congo came into contact with humans (Avert, 2016). Though reports were not identified as HIV until the 1980’s, the belief that HIV was already scattered throughout four other continents may have been incident (Avert, 2016). Even though for the past 30 years the world has been diligently working to find a cure and pushing prevention, we are still struggling each year with increasing diagnosis. The beginning of HIV did end with lots of death, but now with our improved antiviral medication there is hope for many.
Human Immunodeficiency Virus (HIV) is an incurable illness that can lead to Acquired Immune Deficiency Syndrome (AIDS) - a life-threatening condition (CDC.gov). According to the Center for Disease Control and Prevention, an estimated 1, 218, 4000 people aged 13 and older are living with HIV in the United States.
HIV is the human immunodeficiency virus that causes AIDS. A member of a group of viruses called retroviruses, HIV infects human cells and uses the energy and nutrients provided by those cells to grow and reproduce. AIDS (acquired immunodeficiency syndrome) is a disease in which the body's immune system breaks down and is unable to fight off certain infections, known as "opportunistic infections," and other illnesses that take advantage of a weakened immune system. When a person is infected with HIV, the virus enters the body and lives and multiplies primarily in the white blood cells. These are the immune cells that normally protect us from disease.
