Elisa: The First Hiv Blood Test
In CDCs immunology lab, scientists began working with AIDS specimens as early as July 1981 to understand how the immune systems of young, healthy men were so compromised by the mystery illness. In a photograph from 1983 displayed here, a female CDC research chemist conducts tests on biological fluids from AIDS patients. This work contributed to the theory that an infectious agent, not a genetic defect, was the cause of the disease. CDCs virology labs were among a network of international research centers searching for the virus believed to be the cause of AIDS.
By the next year, the U.S Food and Drug Administration licensed the first commercial blood test, ELISA, to detect HIV. Blood banks begin screening the U.S. blood supply. In a photograph on display, a different CDC lab technician is performing the ELISA test. Using a plastic plate with 96 wells, the lab technician adds the patients blood to different enzymes. Certain reactions between the blood and the enzymes indicated the presence of HIV antibodies.

Unexplained cases of enlarged lymph nodes among gay men are observed and studied by physicians and researchers in New York City, including Dr. Mathilde Krim.
Drs. Michael S. Gottlieb, Joel D. Weisman, et al., report five cases of homosexual men with Pneumocystis carinii pneumonia, a rare form of pneumonia usually found only in severely immunosuppressed patients. The report is published in the June 5, 1981, issue of the U.S. Centers for Disease Control and Preventions Morbidity and Mortality Weekly Report . Drs. Gottlieb and Weisman later are among amfARs founding directors. The July 3, 1981, MMWR reports 26 cases of Kaposis sarcoma , a rare cancer, in homosexual men in both New York and California. The New York Times publishes the first news article about the mysterious new disease. Initial use of the term gay-related immune deficiency or gay cancer by the media and others mistakenly suggests an inherent link between homosexuality and the new disease. The first AIDS service organization, Gay Mens Health Crisis , is founded in New York City. U.S.
YEAR-END STATISTICS A total of 159 cases of the new disease are recorded in the U.S.
Brief Information About Midlands Aids Caring Organisation
Midlands AIDS Caring Organisation is a legally registered private voluntary organisation operating in the Midlands province of Zimbabwe. The organisation was founded on the premise of responding to shocks particularly the HIV & AIDS pandemic and drought that severely affected the social and economic lives of communities in most parts of Zimbabwe. The community based and driven organisation is governed by a board which was appointed on gender and commitment merit. Midlands AIDS Caring Organisationâs operations is influenced by policy and a robust strategic plan that defines the organisationâs work.

A Look Back At Robert Bazell’s 1982 Aids Report
When Grossman attended a packed meeting convened by Larry Kramer and the newly formed Gay Mens Health Crisis in 1983, that was when people realized something really bad was going on, he said.
As a medical resident in a Brooklyn hospital that same year when much of the public still thought this mysterious illness primarily affected gay men Grossman saw intravenous drug users, people of Caribbean descent and women who, in retrospect, he believes were exhibiting symptoms of AIDS.
Less than a decade later, Ivy Kwan Arce, a long-term survivor of AIDS and an ACT UP member, said she encountered disbelief when she asked her doctor for an HIV test after seeing an ACT UP poster that said, Women dont get AIDS. … They just die from it, with fine print recommending that women with multiple sexual partners or who are drug users get tested.
At the time, the CDC’s definition of AIDS excluded medical conditions experienced by women who were later known to have the disease, causing the government to undercount the number of women who had died due to AIDS-related complications. Kwan participated in activism that pushed the government to expand the definition of AIDS to include specific conditions for women, alongside Katrina Haslip, an HIV/AIDS activist and fellow ACT UP member who died in 1992 from complications of AIDS, according to a New York Times obituary.

Th Anniversary Of The First Reported Cases Of Aids In The United States
HIV.gov| June 05, 2018
June 5 is an important anniversary in the history of HIV and AIDS in the United States. On this date in 1981 the U.S. Centers for Disease Control and Prevention published a Morbidity and Mortality Weekly Report , describing cases of a rare lung infection, Pneumocystis carinii pneumonia , in five young, previously healthy, gay men in Los Angeles. All the men had other unusual infections as well, indicating that their immune systems were not working two had already died by the time the report is published. This edition of the MMWR marked the first official reporting on what would later become known as AIDS.
The cause of the new, unexplained illness was unknown. But the editorial note that accompanied the MMWR report stated that the case histories suggested a “cellular-immune dysfunction related to a common exposure” and a “disease acquired through sexual contact.” Within days after the MMWR was published, additional similar case reports from New York City, San Francisco, and other cities were sent to CDC. Now we know that their disease resulted from infection with HIV and that this was the dawn of the HIV epidemic in the United States.

Impact Across The Country
- Although HIV has been reported in all 50 states, the District of Columbia, and U.S. dependencies, the impact of the epidemic is not uniformly distributed.
- Ten states accounted for about two-thirds of HIV diagnoses among adults and adolescents in 2019 .31 Regionally, the South accounted for more than half of HIV diagnoses in 2019.32
- Rates of HIV diagnoses per 100,000 provide a different measure of the epidemicâs impact, since they reflect the concentration of diagnoses after accounting for differences in population size across states. The District of Columbia has the highest rate in the nation, compared to states, nearly 3 times the national rate and Georgia was the state with highest rate , twice that of the national rate.33,34 Nine of the top 10 states by rate are in the South.35
- New HIV diagnoses are concentrated primarily in large U.S. metropolitan areas , with Miami, Orlando, and Atlanta topping the list of the areas most heavily burdened.36

Where Did Aids Come From
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. Chimps, the scientist later discovered, hunt and eat two smaller species of monkeysred-capped mangabeys and greater spot-nosed monkeysthat carry and infect the chimps with two strains of SIV. These two strains likely combined to form SIVcpz, which can spread between chimpanzees and humans.
SIVcpz likely jumped to humans when hunters in Africa ate infected chimps, or the chimps infected blood got into the cuts or wounds of hunters. Researchers believe the first transmission of SIV to HIV in humans that then led to the global pandemic occurred in 1920 in Kinshasa, the capital and largest city in the Democratic Republic of Congo.
The virus spread may have spread from Kinshasa along infrastructure routes via migrants and the sex trade.
In the 1960s, HIV spread from Africa to Haiti and the Caribbean when Haitian professionals in the colonial Democratic Republic of Congo returned home. The virus then moved from the Caribbean to New York City around 1970 and then to San Francisco later in the decade.
International travel from the United States helped the virus spread across the rest of the globe.

Origin And Epidemic Emergence
Several of the theories of HIV origin accept the established knowledge of the HIV/SIV phylogenetic relationships, and also accept that bushmeat practice was the most likely cause of the initial transfer to humans. All of them propose that the simultaneous epidemic emergences of four HIV groups in the late 19th-early 20th century, and the lack of previous known emergences, are explained by new factor that appeared in the relevant African regions in that timeframe. These new factor would have acted either to increase human exposures to SIV, to help it to adapt to the human organism by mutation , or to cause an initial burst of transmissions crossing an epidemiological threshold, and therefore increasing the probability of continued spread.
Genetic studies of the virus suggested in 2008 that the most recent common ancestor of the HIV-1 M group dates back to the Belgian Congo city of Léopoldville , circa 1910. Proponents of this dating link the HIV epidemic with the emergence of colonialism and growth of large colonial African cities, leading to social changes, including a higher degree of non-monogamous sexual activity, the spread of prostitution, and the concomitant high frequency of genital ulcer diseases in nascent colonial cities.

Activism By Aids Patients And Families
Also in 1982, Michael Callen and Richard Berkowitz published How to Have Sex in an Epidemic: One Approach. In this short work, they described ways gay men could be sexual and affectionate while dramatically reducing the risk of contracting or spreading HIV. Both authors were themselves gay men living with AIDS. This booklet was one of the first times men were advised to use condoms when having sexual relations with other men.
At the beginning of the AIDS epidemic in the 1980s, there was very little information about the disease. Because AIDS affected stigmatized groups, such as LGBTQ people, people of low socioeconomic status, sex workers and addicts, there was also initially little mass media coverage when the epidemic started. However, with the rise of activist groups composed of people suffering from AIDS, either directly or through a loved one, more public attention was brought to the epidemic.
He Was Uncommunicative With Doctors
Doctors described Rayford as uncommunicative and withdrawn. He refused to allow doctors to perform a rectal examination. Dr. Memory Elvin-Lewis, who cared for Rayford, later said of him that He was the typical 15-year-old who is not going to talk to adults, especially when Im white and hes black. He was not a communicative individual. He knew the minute I walked into the room that I wanted something more from himmore blood, more lymph fluid, more something.
Rayford also gave conflicting statements about his sexual history. He once boasted that he was the stud of all time, and another time claimed that he had only had sexual intercourse once, with a young woman from his neighbourhood, to whom he attributed his illness. He was eventually moved to Barnes-Jewish Hospital .
In late 1968, Rayfords condition appeared to improve, but by early 1969 his symptoms had worsened he had severe difficulty breathing and his white cell count was dangerously low. Doctors realised that his immune system was dysfunctional, and he died of pneumonia on 15 May 1969.

Access to healthcare is very important in preventing and treating HIV/AIDS. It can be affected by health insurance which is available to people through private insurers, Medicare and Medicaid which leaves some people still vulnerable. Historically, African-Americans have faced discrimination when it comes to receiving healthcare.
Homosexuality is viewed negatively in the African-American Community. “In a qualitative study of 745 racially and ethnic diverse undergraduates attending a large Midwestern university, Calzo and Ward determined that parents of African-American participants discussed homosexuality more frequently than the parents of other respondents. In analyses of the values communicated, Calzo and Ward reported that Black parents offered greater indication that homosexuality is perverse and unnatural”.

His Autopsy Was Equally Confusing
Rayfords autopsy presented more issues than it solved. It revealed small, cancerous tumours throughout his body, which were concluded to be Kaposis sarcoma, a rare cancer that normally affected elderly men of Mediterranean and Ashkenazi Jewish ancestry, but was almost unheard of amongst Black teenagers. This sarcoma was later designated as an AIDS-defining illness.
These findings further baffled the attending doctors, and a review of the case was published in 1973 in the medical journal Lymphology.

The Patient Zero Myth
For decades, a French-Canadian airline employee named Gaetan Dugas, has been known as Patient Zero in the 1980s AIDS epidemic.
Dugas, a man who had sex with men , died in 1984. Since then he has been blamed by some as a primary source for the spread of HIV in North America.
Dugas was one of the primary villains in the 1987 book, And the Band Played On, by San Francisco journalist Randy Shilts.
However, the researchers now say Dugas was falsely accused and unfairly blamed.
Gaetan Dugas is one of the most demonized patients in history, and one of a long line of individuals and groups vilified in the belief that they somehow fueled epidemics with malicious intent, said Richard McKay, D.Phil., a Wellcome Trust Research Fellow in Cambridges Department of History and Philosophy of Science, in a press release.
In fact, McKay says, Dugas actually provided scientists with valuable information before he died.
Dugas told researchers after he contracted HIV that he had 750 sexual partners the previous three years. That wasnt necessarily an unusual number. Researchers said 65 percent of men in a Los Angeles cluster study at the time reported having more than 1,000 sexual partners in their lifetimes.
Much of that sexual connection was with anonymous partners, so many HIV patients couldnt give medical officials any names.
However, McKay says, Dugas provided medical officials with 72 names. That helped scientists track down a wide range of people infected with HIV.
