What Happened In The 1980s In The Usa
People sometimes say that HIV started in the 1980s in the United States of America , but in fact this was just when people first became aware of HIV and it was officially recognised as a new health condition.
In 1981, a few cases of rare diseases were being reported among gay men in New York and California, such as Kaposi’s Sarcoma and a lung infection called PCP.1516 No one knew why these cancers and opportunistic infections were spreading, but they concluded that there must be an infectious ‘disease’ causing them.
At first the disease was called all sorts of names relating to the word ‘gay’.17 It wasn’t until mid-1982 that scientists realised the ‘disease’ was also spreading among other populations such as haemophiliacs and heroin users.1819 By September that year, the ‘disease’ was finally named AIDS.20
It was only in 1983 that the HIV virus was isolated and identified by researchers at the Pasteur Institute in France. Originally called Lymphadenopathy-Associated Virus the virus was confirmed as the cause of AIDS, when scientists working at the USA National Cancer Institute isolated the same virus and called it HTLV-III. LAV and HTLV-III were later acknowledged to be the same.
The Origin Of The Aids Virus
From time to time, new diseases are discovered. In the past 20 or so years we have seen new diseases like hantavirus, ebola virus, Legionnaires’ disease, lyme disease, chronic fatigue syndrome and toxic shock syndrome. Among these new diseases, AIDS has become the most notorious.
In 1980 and 1981, doctors in the United States discovered that young gay men and IV-drug users, were mysteriously getting diseases most often seen when the immune system is damaged. As the months progressed, more and more people in these groups began to die from diseases associated with a damaged immune system. This trend was also beginning to be seen in Western Europe. As the numbers began to dramatically increase, it became clear that a new disease was upon us. AIDS was identified as a new disease in 1981. Human immunodeficiency virus was co-discovered several years later by Luc Montagnier and Robert Gallo.
AIDS is caused by HIV. HIV is believed to have originated in Africa sometime between the late 1940s and the early 1950s. The earliest known case was in a man from the Belgian Congo in 1959 .
Once HIV entered humans, over time it spread person-to-person primarily through heterosexual contact. In fact, even today, most of the worlds HIV/AIDS cases are spread by heterosexual contact, not by homosexual contact or by needle sharing.
Until next time . . . Work hard, play hard, play safe, stay sober!

The first well-recorded European outbreak of what is now known as syphilis occurred in 1494 when it broke out among French troops besieging Naples in the Italian War of 149498. The disease may have originated from the Columbian Exchange.

New Study Shows Hiv Epidemic Started Spreading In New York In 1970
A new genetic study confirms theories that the global epidemic of HIV and AIDS started in New York around 1970, and it also clears the name of a gay flight attendant long vilified as being “Patient Zero.”
Researchers got hold of frozen samples of blood taken from patients years before the human immunodeficiency virus that causes AIDS was ever recognized, and teased out genetic material from the virus from that blood.
They use it to show that HIV was circulating widely during the 1970s, and certainly before people began noticing a gay plague in New York in the early 1980s.
History Of Hiv And Aids Overview
The history of the HIV and AIDS epidemic began in illness, fear and death as the world faced a new and unknown virus. However, scientific advances, such as the development of antiretroviral drugs, have enabled people with access to treatment to live long and healthy lives with HIV.
Here, we go through the key historical moments that have defined the HIV epidemic over the past 30 years.

When And Where Did Hiv Start In Humans
Studies of some of the earliest known samples of HIV provide clues about when it first appeared in humans and how it evolved. The first verified case of HIV is from a blood sample taken in 1959 from a man living in what is now Kinshasa in the Democratic Republic of Congo. The sample was retrospectively analysed and HIV detected. There are numerous earlier cases where patterns of deaths from common opportunistic infections, now known to be AIDS-defining, suggest that HIV was the cause, but this is the earliest incident where a blood sample can verify infection.9
Where Did Aids Originally Start
. Similarly, it is asked, how did AIDS start in the first place?
They believe that the chimpanzee version of the immunodeficiency virus most likely was transmitted to humans and mutated into HIV when humans hunted these chimpanzees for meat and came into contact with their infected blood.
who was the first person to get AIDS? 1980s. April 24, San Francisco resident Ken Horne is reported to the Center for Disease Control with Kaposi’s sarcoma . Later in 1981, the CDC would retroactively identify him as the first patient of the AIDS epidemic in the US. He was also suffering from Cryptococcus.
Also Know, where did AIDS come from and how did it start?
Scientists have traced the origin of HIV back to chimpanzees and simian immunodeficiency virus , an HIV-like virus that attacks the immune system of monkeys and apes. In 1999, researchers identified a strain of chimpanzee SIV called SIVcpz, which was nearly identical to HIV.
How did the AIDS epidemic start in America?
The AIDS epidemic, caused by HIV , found its way to the United States as early as 1960, but was first noticed after doctors discovered clusters of Kaposi’s sarcoma and pneumocystis pneumonia in gay men in Los Angeles, New York City, and San Francisco in 1981.

Individual Symptoms Of Hiv Vary From One Person To Another If You Have An Active Sex Life Or Think You May Have Been Exposed To Hiv It Is Important To Get Tested Here Are Some Common Symptoms Of Hiv Many People Experience Severe Flu
This article is also available in Simplified Chinese and Thai.
Symptoms of HIV can vary between individuals however the first signs of infection generally appear within the first 1-2 months. Many, but not all, people will experience severe flu-like symptoms which is your bodys natural response to the virus. This is called the seroconversion period.
Its during this time that its crucial to identify if HIV is the cause, as your viral load is very high which greatly increases the risk of passing it on. And the only way to know for sure is by getting tested.
Does Hiv Viral Load Affect Getting Or Transmitting Hiv
Yes. Viral load is the amount of HIV in the blood of someone who has HIV. Taking HIV medicine daily as prescribed can make the viral load very lowso low that a test cant detect it .
People with HIV who take HIV medicine daily as prescribed and get and keep an undetectable viral load have effectively no risk of transmitting HIV to an HIV-negative partner through sex.
HIV medicine is a powerful tool for preventing sexual transmission of HIV. But it works only as long as the HIV-positive partner gets and keeps an undetectable viral load. Not everyone taking HIV medicine has an undetectable viral load. To stay undetectable, people with HIV must take HIV medicine every day as prescribed and visit their healthcare provider regularly to get a viral load test. Learn more.

Canadian Flight Attendant Theory
A Canadian airline steward named Gaëtan Dugas was referred to as “Case 057” and later “Patient O” with the alphabet letter “O” standing for “outside Southern California”, in an early AIDS study by Dr. William Darrow of the Centers for Disease Control. Because of this, many people had considered Dugas to be responsible for taking HIV to North America. However, HIV reached New York City around 1971 while Dugas did not start work at Air Canada until 1974. In Randy Shilts‘ 1987 book And the Band Played On , Dugas is referred to as AIDS’s Patient Zero instead of “Patient O”, but neither the book nor the movie states that he had been the first to bring the virus to North America. He was incorrectly called “Patient Zero” because at least 40 of the 248 people known to be infected by HIV in 1983 had had sex with him, or with a person who had sexual intercourse with Dugas.
Spread To The Western Hemisphere
Further isolated occurrences of this infection may have been emerging as early as 1966. The virus eventually entered gay male communities in large United States cities, where a combination of casual, multi-partner sexual activity and relatively high transmission rates associated with anal intercourse allowed it to spread explosively enough to finally be noticed.
Because of the long incubation period of HIV before symptoms of AIDS appear, and because of the initially low incidence, HIV was not noticed at first. By the time the first reported cases of AIDS were found in large United States cities, the prevalence of HIV infection in some communities had passed 5%. Worldwide, HIV infection has spread from urban to rural areas, and has appeared in regions such as China and India.

So Scientists Have Estimated When And Where The Most Deadly Type Of Hiv Started Infecting Humans
Most AIDS researchers believe that the “bushmeat trade” allowed the HIV-1 virus, and separately HIV-2, to enter the human bloodstream several times. Hunters who kill and butcher chimps and monkeys are regularly exposed to animal blood teeming with SIVs. If the hunters have cuts, bites, or scratches — and given the nature of their work they almost always do — they can catch the viruses from their prey. Hunters going after chimps in Cameroon could have caught the first strains of HIV-1. Sooty mangabeys, hunted and kept as pets in West Africa, could have transmitted HIV-2 to humans.
Africans have hunted chimps and monkeys and kept them as pets for centuries they’ve presumably been exposed to SIVs during most of that time. But the conditions needed for HIV to spread widely weren’t in place until after the continent was colonized and urbanized. The first victims would have found it easier to unwittingly spread the virus to sexual partners far and wide as roads and vehicles started connecting previously isolated villages and cities. Hospitals may have played a role, too. Strapped for cash, some of them probably re-used dirty needles, unknowingly infecting patients in the process.
Years Ago: The First Aids Patients Were Diagnosed
It infects men, women and children alike, is passed to newborns from infected mothers, and spreads like wildfire in infected needles shared by drug users.
But in the early 1980s in New York and San Francisco, all people knew was that something mysterious was killing gay men.
Death and dying was such a part of our daily lives.”
“In New York City, the virus encountered a population that was like dry tinder, causing the epidemic to burn hotter and faster and infecting enough people that it grabs the world’s attention for the first time, Worobey said in a statement.
Death and dying was such a part of our daily lives, said Sean Strub, a writer and activist who has been HIV positive since the 1980s.
Once the virus was identified, researchers could start working on treatments and diagnostic tests. And specialists like Worobey could look at the genetics of the virus itself to find its origins.
But no one had samples of HIV infected blood from before the 1980s.
Worobeys team got nine samples and sequenced the RNA from eight of them. It wasnt easy to get and was damaged, so they used new techniques similar to those used to reconstruct DNA from ancient Neanderthal remains.
The different mutations in the genetic material DNA from people, RNA from the virus can provide a genetic clock. The more diversity, the more time a virus has been circulating and acquiring small mutations.
“That information is stamped into the RNA of the virus from 1970,” Worobey said.

Ways Hiv Cannot Be Spread
HIV is not spread by:
- Air or water
- Mosquitoes, ticks or other insects
- Saliva, tears, or sweat that is not mixed with the blood of a person with HIV
- Shaking hands hugging sharing toilets sharing dishes, silverware, or drinking glasses or engaging in closed-mouth or social kissing with a person with HIV
- Drinking fountains
Origin And Distribution Of Sivcpz
Of the many primate lentiviruses that have been identified, SIVcpz has been of particular interest because of its close genetic relationship to HIV-1 . However, studies of this virus have proven to be challenging because of the endangered status of chimpanzees. The first isolates of SIVcpz were all derived from animals housed in primate centers or sanctuaries, although infection was rare in these populations. Collective analyses of nearly 2,000 wild-caught or captive-born apes identified fewer than a dozen SIVcpz positive individuals . Because other primate species, such as sooty mangabeys and African green monkeys, are much more commonly infected, both in captivity and in the wild , this finding raised doubts about whether chimpanzees represented a true SIV reservoir. To resolve this conundrum, our laboratory developed noninvasive diagnostic methods that detect SIVcpz specific antibodies and nucleic acids in chimpanzee fecal and urine samples with high sensitivity and specificity . These technical innovations, combined with genotyping methods for species and subspecies confirmation as well as individual identification, permitted a comprehensive analysis of wild-living chimpanzee populations throughout central Africa.

Where Did Hiv Come From A Look At The Origins Of The Pandemic Of Our Time
A chimpanzees virus has killed 35 million humans.
That virus, commonly known as HIV, is the defining pandemic of our time. More than 35 million people have been killed by the virus to date. But the virus itself didnt get its start in humans.
HIV/AIDS is, like the vast majority of emerging viruses infecting people, zoonotic in nature. The AIDS crisis, as we generally think of it, began in the 1980s. First as a mysterious illness primarily infecting gay men in urban areas in the United States. But thats not really the beginning. Before the diseases first mention in 1982 in the New York Times, people had been dying of AIDS for at least a decade, though probably not much longer. In Africa, HIVthe virus that causes AIDShad jumped from chimpanzees to humans sometime early in the 20th century.
To date, the earliest known case of HIV-1 infection in human blood is from a sample taken in 1959 from a man whod died in Kinshasa in what was then the Belgian Congo.
Its this fact which keeps me awake at night. Imagine, for a moment, that the HIV virus in that 1959 sample had been studied and identified. If, in the 1950s, the scientific community realized the potential harm this new virus could unleash. What could we have done? What therapies could we have developed before it became one of the deadliest pandemics in human history? Would we have a cure by now?
That work takes several forms, including:
Aids: Origin Of Pandemic ‘was 1920s Kinshasa’
Health editor, BBC News website
The origin of the Aids pandemic has been traced to the 1920s in the city of Kinshasa, in what is now the Democratic Republic of Congo, scientists say.
An international team of scientists say a “perfect storm” of population growth, sex and railways allowed HIV to spread.
A feat of viral archaeology was used to find the pandemic’s origin, the team report in the journal Science.
They used archived samples of HIV’s genetic code to trace its source, with evidence pointing to 1920s Kinshasa.
Their report says a roaring sex trade, rapid population growth and unsterilised needles used in health clinics probably spread the virus.
Meanwhile Belgium-backed railways had one million people flowing through the city each year, taking the virus to neighbouring regions.
Experts said it was a fascinating insight into the start of the pandemic.
HIV came to global attention in the 1980s and has infected nearly 75 million people.
It has a much longer history in Africa, but where the pandemic started has remained the source of considerable debate.

Stigma In The Early Years
When the first few cases of AIDS emerged, people believed the disease was only contracted by men who had sex with men. The CDC called this infection GRIDS, or gay-related immunodeficiency syndrome. Shortly after, the CDC published a case definition calling the disease AIDS.
Public response was negative in the early years of the epidemic. In 1983, a doctor in New York was threatened with eviction, leading to the first AIDS discrimination lawsuit.
Bathhouses across the country closed due to high-risk sexual activity. Some schools also barred children with HIV from attending.
In 1987, the United States placed a travel ban on visitors and immigrants with HIV. President Obama lifted this ban in 2010.
The United States government resisted funding needle exchange programs due to the war on drugs. NEPs were shown to be effective at reducing HIV transmission. Some believe that this resistance accounts for 4,400 to 9,700 avoidable transmissions.
