Human Immunodeficiency Virus
The Human Immunodeficiency Virus, also known as HIV, comes with a long line of history and theories. One of the most common theories of the Human Immunodeficiency Virus is the hunter theory. The hunter theory explains the belief that the HIV virus came from chimpanzees. It is believed that the virus came from infected chimps being hunted and killed. It expresses that the virus was spread through then eating the meat of the infected chimp meat or by getting the blood of the infected chimp into wounds or cuts. The theory states that the original virus found in these chimps known as the Simian Immunodeficiency Virus (SIV), mutated when it got in contact with the human body and evolved to the HIV virus we know today. Another common theory is the contaminated needle theory which states that African healthcare workers were giving different sorts of vaccinations with the same needle. It was believed to have spread through one of the patients given a vaccination with HIV which was then spread to many others with the use of the same needle. An important factor about the history of HIV is how politics in the United States and around the world reacted to this virus. The first cases of HIV were publicly released in reports by the Center of Disease Control (CDC) to the Morbidity and Mortality Weekly Reports (MMWR) where in 1981 five men were confused to have a rare form of pneumonia. All five men
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.
It is often cited that the HIV/Aids epidemic that hit the United States in the 1980’s (though there is some evidence that it started even before then), came into light due to several high profile incidents and the eventual loss of several thousand lives. Many believe that due to
In the Radio Lab the Authors illustrates how HIV is spreading in United States and how the starting point begins as Patient Zero. Jad Abumrad and Robert Krulwich along with Carl Zimmer and David Quammen discuss how in 1981 a mysterious syndrome it became in a pandemic among homosexual people in important cities such as Los Angeles Ney York and San Francisco. Young men were dying in inexplicable conditions that the CDC had to intervene with a several researches, surveys and studies about those cases. During the research noticed that one man were most related with more cases, this person was Gaetan Dugas, a Canadian young men, who travel to US. As he knew he was going to die, he stared to spread the disease for something he called a “gay cancer”.
It wasn’t until 1989 that scientists discovered the presence of HIV in the blood in AIDS patients. Scientists then transferred their efforts towards treating HIV. This spurred a research on a global scale as this breakthrough in the now HIV/AIDS epidemic has come to the light. The now FDA and CDC were major
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,”
According to a report published in the February 1998 edition of “Nature”, scientists identified what they believe is the earliest case of AIDs in a man from the Congo in 1959. (Lerner and Hombs 39) By the end of the year 1980, 80 men would have been diagnosed with at least of the opportunistic infections that are a characteristic of AIDs. (Lerner and Hombs 40) AIDs cases in the 1980s increased dramatically not only around the world but in the United States, primarily in larger cities like Los Angeles, New York City and San Francisco. The numbers of AIDs diagnoses and deaths spiraled out of control throughout the 1980s and towards the end of 1989 there were 117,500 cases of AIDS reported and 89,000 related deaths.(Lerner and Hombs 54) In the
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
In the 1980s, a mysterious disease began to take the lives of Americans. With the cause unknown, a fear grew among Americans. An unusually high rate of people was becoming sick with strange and rare diseases. When experimental treatments failed to work, people died. This mysterious disease is what we now know as HIV–Human Immunodeficiency Virus. In the past thirty-five years, the HIV has taken many turns in history. Although we do not hear about HIV and AIDS now, it is still a prevalent issue in the United States and in the world.
The first documented case of HIV was in 1959. It is believed that HIV may have been spreading throughout the United States since 1966. Allegedly the spread of HIV and AIDS across the United States can be traced all the way back to an unnamed male who contracted the disease while in Haiti and brought it to the US. It did not take long for the disease to spread uncontrollably throughout the U.S, infamously throughout the homosexual community. In 1981, the initial cases of AIDS were a group of homosexual males with no recorded cases of impaired immunity who displayed symptoms of Pneumocystis carinii pneumonia, an uncommon infection that typically
In 1920 a disease would enter the world in change lives of many people around the world. The most powerful scientists and researchers tired to find answers regarding the strange disease but unfortunately they will spend years with unanswered questions. In this research paper, I decided to look back and discuss evidence about the origin of HIV, and find out where, how, and when the disease first began to cause illness in humans. However, this paper will mainly focus on how HIV impacts the community worldwide.
In the 1920's, HIV crossed from chimps to humans. There is evidence on how, when and where HIV first began to cause illness in humans. HIV is a type of lentivirus, which means it attacks the immune system. In a similar way, the Simian Immunodeficiency Virus (SIV) attacks the immune systems of monkeys and apes. There is even a theory on hunters, in the Democratic Republic of Congo eating monkey and transfer the virus. These well-known diseases, travel from Africa, Kinshasa to the United States. Started off being called GRID also known as gay-related immune deficiency introduced to united state in 1981. This disease has taken 121 healthy gay man lives in the U.S. since the mid-1970s. Scientists began to notice clusters of Kaposi's sarcoma and
In the late 1970’s AIDS was just introduced, others knew it as the “gay plague.” In Manhattan, the government was thought to have made HIV later introduced as the main leading cause of AIDS, to use it as a weapon of genocide against gay men.
In 1920, HIV originated in Kinshasa, Democratic Republic of Congo when it crossed species from chimpanzees to humans. Up until the 1980s, researchers did not know how many people were infected with this disease. HIV was completely unknown and the transmission was not connected with the noticeable signs or symptoms. Also, HIV may have already spread to five continents of the world: North America, South America, Europe, Africa and Australia. In this period, between 100,000 and 300,000 people could have already been infected. In June 1982, a of cases among gay men in Southern California suggested that the cause of the Human immune deficiency or HIV was sexually transmitted. This disease was initially called gay-related immune deficiency or “GRID”.
June 5, 1981 became known as the date of the official onset of HIV/AIDS epidemic when a Doctor released the stories of Patient Zero and four other cases to the Centers for Disease Control (Gottlieb, 2006). Doctors around the United States start recognizing AIDS cases. There were a total of 164 cases reported between 1979 and 1983, with 60% of those cases being reported in 1983 alone. The highest risk groups were homosexual men at 71%, drug users at 17%, Haitians at 5%, and hemophiliacs at less than 1%. Europe reported the same groups at risk.
HIV and AIDS have affected millions of people throughout the world. Since 1981, there have been 25 million deaths due to AIDS involving men, women, and children. Presently there are 40 million people living with HIV and AIDS around the world and two million die each year from AIDS related illnesses. The Center for Disease Control estimates that one-third of the one million Americans living with HIV are not aware that they have it. The earliest known case of HIV was in 1959. It was discovered in a blood sample from a man in Kinshasa, Democratic Republic of the Congo. Looking further into the genetics of this blood sample researchers suggested that it had originated from a virus going back to the late 1940’s or early 1950’s. In 1999,
