History of HIV/AIDS The majority of HIV researchers agree that HIV evolved at some point from the closely related Simian immunodeficiency virus (SIV), and that SIV or HIV (post mutation) was transferred from non-human primates to humans in the recent past (as a type of zoonosis).he majority of HIV researchers agree that HIV evolved at some point from the closely related Simian immunodeficiency virus (SIV), and that SIV or HIV (post mutation) was transferred from non-human primates to humans in the recent past (as a type of zoonosis).

Did AIDS come from having sex with monkeys? All evidence indicates that the monkey AIDS virus (also known as Simian Immunodeficiency Virus or SIV), and even the cat AIDS virus (also known as Feline Immunodeficiency Virus or FIV) have been in existence long before the HIV virus first infected humans.

- By Dr Ananya Mandal, MD. HIV or Human Immunodeficiency virus is a retrovirus that was first found in 1983. The virus is responsible for causing AIDS (acquired immunodeficiency syndrome). Once within the body the HIV infects cells of the immune system that form the body’s defence system and makes them unable to fight off infections.

History of HIV/AIDS The authors proposed that HIV-1 originated in the area of French Equatorial Africa in the early 20th century (when the colonial abuses and forced labor were at their peak). Later researches proved these predictions mostly correct: HIV-1 groups M and O started to spread in humans in late 19th–early 20th century.

HIV-2 In 1986, a second type of HIV, called HIV-2, was isolated from AIDS patients in West Africa, where it may have been present decades earlier. Studies of the natural history of HIV-2 are limited, but to date comparisons with HIV-1 show some similarities while suggesting differences.

History of syphilis The history of syphilis has been well studied, but the exact origin of syphilis is unknown. There are two primary hypotheses: one proposes that syphilis was carried to Europe from the Americas by the crew of Christopher Columbus, the other proposes that syphilis previously existed in Europe but went unrecognized.n 1905, Schaudinn and Hoffmann discovered Treponema pallidum in tissue of patients with syphilis. One year later, the first effective test for syphilis, the Wassermann test, was developed.

Where did HIV come from? For many years scientists theorized as to the origins of HIV and how it appeared in the human population, most believing that HIV originated in other primates. Then in 1999, an international team of researchers reported that they had discovered the origins of HIV-1, the predominant strain of HIV in the developed world. A subspecies of chimpanzees native to west equatorial Africa had been identified as the original source of the virus.

Did This 'Swine Flu' Really Come From Pigs? So what we think is, somewhere these two viruses -- the virus in pigs in the Americas, the virus in pigs in Asia -- got together and formed this particular virus that's now come into humans. So the answer is, one, yes. In terms of its genetic makeup, this virus did come from pigs. What we can't say with any certainty, however, is that this virus transmitted directly from pigs into humans. It's also possible that this virus, these two viruses got together in another host, perhaps an avian host, and then went from that avian host into humans. Comments.

Polio vaccines and the origin of AIDS: some key writings Overview of the theory. One theory of the origin of AIDS is that it developed from contaminated vaccines used in the world's first mass immunisation for polio. There are a number of reasons why this theory is plausible enough to be worthy of further investigation. The location coincides dramatically.

The Origin of AIDS and HIV May Not Be What You Have Learned By the end of the symposium, the esteemed delegates concluded HIV's origin, and AIDS, was not likely to have come from polio vaccine transmissions as chimpanzees were not proven to have been used during the manufacture of this vaccine. The hepatitis B vaccine was not considered by this esteemed gathering.

Did first humans emerge from Middle East, not Africa? Other scientists have argued that human beings originated in Africa before moving to other regions 150,000 to 200,000 years ago. Homo sapiens discovered in Middle Awash, Ethiopia, from 160,000 years ago were believed to be the oldest 'modern' human beings. Other remains previously found in Israeli caves are thought to have been more recent and 80,000 to 100,000 years old.

How Ebola Emerged Out of the Jungle Origin of the disease. The first reported case of the deadly virus came in 1976 and it is named after the Ebola River in the Democratic Republic of Congo which was where it was discovered. At the time, the area where the disease was spotted was officially recognized as Zaire.

Human T- Lymphotropic Virus (HTLV) They are only distantly related to the human immunodeficiency viruses (HIV-1 and HIV-2), which belong to the lentivirus subfamily of retroviruses and which cause acquired immunodeficiency syndrome (AIDS). Infections with HTLV-I and HTLV-II are most easily detected by a blood test.TLV is a human retrovirus that was discovered in 1980. Human T-lymphotropic viruses, type I (HTLV-I) and type II (HTLV-II), were the first human retroviruses discovered. Both belong to the oncovirus subfamily of retroviruses.

Origin of HIV & AIDS HIV crossed from chimps to humans in the 1920's in what is now the Democratic Republic of Congo. This was probably as a result of chimps carrying the Simian Immunodeficiency Virus (SIV), a virus closely related to HIV, being hunted and eaten by people living in the area.

History of HIV and AIDS overview It is widely believed that HIV originated in Kinshasa, in the Democratic Republic of Congo around 1920 when HIV crossed species from chimpanzees to humans. Up until the 1980s, we do not know how many people developed HIV or AIDS. HIV was unknown and transmission was not accompanied by noticeable signs or symptoms.

Origin of HIV & AIDS In 1999, researchers found a strain of SIV (called SIVcpz) 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.3.

HIV/AIDS in the United States The epidemic of the immunodeficiency disease AIDS, which began in Sub-Saharan Africa in the 1930s as a mutation of the chimpanzee disease SIV, which was named Human Immunodeficiency Virus, found its way to the shores of the United States as early as 1960, but was first noticed after doctors discovered clusters of Kaposi's sarcoma and pneumocystis pneumonia in young gay men in Los Angeles, New York City, and San Francisco in 1981. This strain was called HIV-1. A second strain, called HIV-2 was di

Life cycle of HIV Because primates are suspected of being the source of HIV, AIDS is considered a zoonosis, an infection that is shared by humans and other vertebrate animals. Genetic studies of a pandemic strain of HIV, known as HIV-1 group M, have indicated that the virus emerged between 1884 and 1924 in central and western Africa.
