The First World Aids Day
At the beginning of the 1980s, before HIV had been identified as the cause of AIDS, the infection was thought to only affect specific groups, such as gay men in developed countries and people who inject drugs. The HIV virus was first isolated by Dr Françoise Barré-Sinoussi and Dr Luc Montagnier in 1983 at the Institut Pasteur. In November that year, WHO held the first meeting to assess the global AIDS situation and initiated international surveillance. It was then that the global health community understood that HIV could also spread between heterosexual people, through blood transfusions, and that infected mothers could transmit HIV to their babies.

After weeks of threats following a ruling that they could not be banned from school for being HIV-positive, the home of brothers Ricky, Robert, and Randy Ray is burned to the ground while the family is staying elsewhere. The Rays later announce that they will leave Arcadia.
The first national AIDS Awareness Month begins, with the CDC launching a massive public education campaign that warns everyone is at risk.
Why Do Scientists Look At Recent Samples Of Hiv To Determine The Virus’ Overall Age Wouldn’t It Be Better To Use Older Samples That Haven’t Had As Much Time To Mutate
It would, but scientists don’t have that luxury. Other than the 1959 sample, there are very few preserved specimens of HIV-infected tissue that predate the early ’80s, when the virus was first recognized by health authorities. Researchers still hope there are forgotten samples in African freezers. “There has to be some serum or plasma somewhere, and given modern technology we could fish out the virus,” says Dr. David Ho, director of the Aaron Diamond AIDS Research Center and one of the world’s leading authorities on HIV.
But even if those samples are found someday, they won’t necessarily yield definite answers about the virus’ age, says Korber: “Often, you can’t get anything out of samples like that.” Most African samples are made of blood serum, and serum samples contain viral RNA, which degrades much faster than the DNA found in tissue samples. In fact, says Ho, the 1959 sample, which was sequenced by his laboratory, was kept in a freezer but still didn’t survive the ravages of time. “It was completely dried up,” he says. “We were only able to get small pieces , and we had to stitch them together.”

Hiv/aids: 40 Years Tackling An Epidemic That Has Marked Humanity
Throughout its 120 years of existence, PAHO has played a leading role in the response to epidemics in the region, including HIV/AIDS. Here are some of the important milestones, as well as the challenges that must be overcome to end AIDS.
Aaron Zea is 32 years old, a manager in the cultural sector, a cyclist who plays soccer every week and lives with HIV. “For me living with HIV is very peaceful because I know that I can have a normal life, play sports and go to university. Im not going to die from this, said Aaron, speaking from his home in Medellín, Colombia. In nine years of living with the virus, he knows what he needs to do to stay healthy – “look after my body, eat well, go to my check-ups and take my medications”.
Today, treatment for HIV is effective and simple and generally consists of a single pill a day, with little to no adverse effects. However, this was not the case for people infected with HIV when Aaron was born in 1990, let alone in 1981, when the first cases of atypical pneumonia were diagnosed in gay men in San Francisco in the United States – something that would forever mark the lives of mankind.
New treatments have turned HIV infection into a chronic disease, and reduced mortality by 28% since 2010 in Latin America. However, this reduction remains below the global average due to huge advances in prevention, early detection, and the rapid initiation of treatment in Africa.
Stigma: Educating A Nation
The first year of the AIDS epidemic seemed isolated to a few individuals in a few cities, so it received little media attention. When cases were reported in infants and people with hemophilia, widespread panic struck Americans. Those with AIDS were often stigmatized. In 1985, Ryan White, a teenage hemophiliac living in Indiana, contracted AIDS from a blood transfusion. Parents in his community feared he would expose their children to AIDS, resulting in Ryan being barred from attending school.
In 1986, U.S. Surgeon General C. Everett Koop issued the Surgeon Generals Report on AIDS. In it, he called for a comprehensive program of sex and AIDS education, urged the widespread use of condoms, and dispelled myths that HIV could be spread by mosquitoes. In 1987, CDC launched an unprecedented national campaign, America Responds to AIDS . The goal of ARTA was to increase awareness and understanding of AIDS, to prevent HIV infection, and to encourage people to seek more information and counseling. CDC also began a program to support HIV prevention efforts with national minority organizations that provided HIV prevention expertise to community-based organizations, developed HIV prevention programs targeting minorities, especially African Americans and Hispanics, and supported groups that used culturally sensitive AIDS prevention programs to address their communities needs.

Where Does Hiv Come From
HIV is thought to have occurred after people ate chimps that were carrying theSimian Immunodeficiency Virus .
HIV is a type of lentivirus, which means it attacks the immune system. SIV attacks the immune systems of monkeys and apes in a very similar way. This suggests HIV and SIV are closely related, and that SIV in monkeys and apes crossed over to humans to become HIV.
What Needs To Happen
The theme of this World AIDS Day Know Your Status is important. One in four people with HIV dont know that they have HIV. To bridge some critical gaps in the availability of HIV tests, WHO recommends the use of self-tests for HIV. WHO first recommended HIV self-testing in 2016, and now more than 50 countries have developed policies on self-testing. WHO, working with international organizations such as Unitaid and others, supported the largest HIV self-testing programmes in six countries in southern Africa. This programme is reaching people who have not tested themselves before, and is linking them to either treatment or prevention services. This World AIDS Day, WHO and the International Labour Organization will also announce new guidance to support companies and organizations to offer HIV self-tests in workplace. People with HIV often have other infections known as co-morbidities such as TB or hepatitis. One in three deaths in people with HIV is from TB. Around 5 million people are living with both HIV and viral hepatitis. One in three people with HIV has heart disease. This has meant that HIV care has long needed joined-up care, although this doesnt always happen in practice. WHO is now promoting person-centred health services to all people living with HIV, to meet their holistic health needs, not just their HIV infection linking HIV services with those for TB, sexual and reproductive health, non-communicable diseases and mental health, says Dr Hirnschall.

Hiv/aids In The 1990s And 2000s
In 1991, the red ribbon became an international symbol of AIDS awareness.
In that year, basketball player Magic Johnson announced he had HIV, helping to further bring awareness to the issue and dispel the stereotype of it being a gay disease. Soon after, Freddie Mercurylead singer of the band Queenannounced he had AIDS and died a day later.
In 1994, the FDA approved the first oral HIV test. Two years later, it approved the first home testing kit and the first urine test.
AIDS-related deaths and hospitalizations in developed countries began to decline sharply in 1995 thanks to new medications and the introduction of HAART. Still, by 1999, AIDS was the fourth biggest cause of death in the world and the leading cause of death in Africa.
The Road To Treatment For All
Until the first half of the 1990s, the drugs available to treat HIV were not effective in controlling the virus. Their cost was prohibitive for many , and public health programs continued to focus on prevention and treatment of the various secondary infections affecting AIDS patients.
Brazil and Argentina were the first countries in Latin America to provide free treatment. But this did not happen immediately in the rest of the countries in the region. However, thanks to the work of activists, and individuals that pursued legal action, many other governments soon began to provide the drugs free of charge through their public health programs.
During the World AIDS Conference in Vancouver, Canada, in 1996, a highly active antiretroviral therapy, or cocktail, was presented. This marked a turning point in treatment, making it possible to prevent the virus from replicating, recover CD4 lymphocytes that fight infection, reduce hospitalizations and improve survival.

Unresolved Questions About Hiv Origins And Emergence
The discovery of the main HIV/SIV phylogenetic relationships permits explaining broad HIV biogeography: the early centres of the HIV-1 groups were in Central Africa, where the primate reservoirs of the related SIVcpz and SIVgor viruses exist similarly, the HIV-2 groups had their centres in West Africa, where sooty mangabeys, which harbour the related SIVsmm virus, exist. However, these relationships do not explain more detailed patterns of biogeography, such as why epidemic HIV-2 groups only evolved in the Ivory Coast, which is one of only six countries harbouring the sooty mangabey. It is also unclear why the SIVcpz endemic in the chimpanzee subspecies Pan troglodytes schweinfurthii did not spawn an epidemic HIV-1 strain to humans, while the Democratic Republic of Congo was the main centre of HIV-1 group M, a virus descended from SIVcpz strains of a subspecies that does not exist in this country. It is clear that the several HIV-1 and HIV-2 strains descend from SIVcpz, SIVgor, and SIVsmm viruses, and that bushmeat practice provides the most plausible cause of cross-species transfer to humans. However, some loose ends remain.
It is not yet explained why only four HIV groups spread considerably in human populations, despite bushmeat practices being widespread in Central and West Africa, and the resulting human SIV infections being common.

New Class Of Antiretrovirals
In 1995, the FDA approved saquinavir, the first in a different anti-HIV drug class called protease inhibitors. Like NRTIs, protease inhibitors stop the virus from copying itself, but at a different stage during the infection.
A year later came yet another class of antiretrovirals, called non-nucleoside reverse transcriptase inhibitor , including nevirapine . Similar to AZT, NNRTIs shut down HIV by targeting the enzymes it needs to multiply.
These drugs paved the way to a new era of combination therapy for HIV/AIDS. Doctors began prescribing saquinavir plus AZT or other antiretrovirals. This combination therapy was dubbed highly active antiretroviral therapy . That approach became the new standard of care for HIV in 1996. HAART greatly lengthened the life span of people with AIDS.
Hiv/aids Is One Of The Worlds Most Fatal Infectious Disease
Almost 1 million people die from HIV/AIDS each year in some countries its the leading cause of death
HIV/AIDS is one of the worlds most fatal infectious diseases particularly across Sub-Saharan Africa, where the disease has had a massive impact on health outcomes and life expectancy in recent decades.
The Global Burden of Disease is a major global study on the causes of death and disease published in the medical journal The Lancet.1 These estimates of the annual number of deaths by cause are shown here. This chart is shown for the global total, but can be explored for any country or region using the change country toggle.
In the chart we see that, globally, it is the second most fatal infectious disease.
According to the Global Burden of Disease study, almost one million people died from HIV/AIDS in 2017. To put this into context: this was just over 50% higher than the number of deaths from malaria in 2017.
Its one of the largest killers globally but for some countries particularly across Sub-Saharan Africa, its the leading cause of death. If we look at the breakdown for South Africa, Botswana or Mozambique which you can do on the interactive chart we see that HIV/AIDS tops the list. For countries in Southern Sub-Saharan Africa, deaths from HIV/AIDS are more than 50% higher than deaths from heart disease, and more than twice that of cancer deaths.

Impact On Gay And Bisexual Men
- While estimates show that gay and bisexual men comprise only about 2% of the U.S. population, male-to-male sexual contact accounts for most new HIV infections and most people living with HIV .57
- Annual new infections among gay and bisexual men declined overall between 2015 and 2019 but remained stable among Black and Latino gay and bisexual men.58
- Blacks gay and bisexual men accounted for the largest number of new diagnoses among this group in 2019, followed by Latino gay and bisexual men .59 Additionally, according to a recent study, Black gay and bisexual men were found to be at a much higher risk of being diagnosed with HIV during their lifetimes compared with Latino and white gay and bisexual men.60 Young Black gay and bisexual men are at particular risk â Black gay and bisexual men ages 20-29 accounted for 51% of new diagnoses among that age group and 13% of all diagnoses.61
Pop Culture Opens Up Conversations
In 1985, actor Rock Hudson became the first major public figure to announce he had AIDS. Before he died that same year, he donated $250,000 to help establish the organization later known as amfAR, the Foundation for AIDS Research. Friend and actress Elizabeth Taylor was the national chairperson until her death in 2011.
In 1987, Princess Diana also made international headlines after she shook hands with an HIV-positive man.
Pop culture icon Freddie Mercury, singer for the band Queen, passed away from AIDS-related illness in 1991. Since then, many other public figures have revealed that theyre HIV-positive, including:
- tennis star Arthur Ashe
- former basketball star and entrepreneur Magic Johnson
- Pedro Zamora, a cast member on MTVs The Real World: San Francisco
- actor Charlie Sheen, who announced his status on national television in 2015
- hairstylist and television personality Jonathan Van Ness
- actor and singer Billy Porter

Tuberculosis Among People Living With Hiv
Tuberculosis is the leading HIV-associated opportunistic infection in low- and middle- income countries, and it is a leading cause of death globally among people living with HIV. Death due to tuberculosis still remains high among people living with HIV, however the number of deaths is decreasing. Most of the global mortality due to TB among those with HIV is from cases in Sub-Saharan Africa.
In the charts here we see the number of tuberculosis patients who tested positive for HIV the number receiving antiretroviral therapy and the number of TB-related deaths among those living with HIV.
People who use ART are living longer
ART not only saves lives but also gives a chance for people living with HIV/AIDS to live long lives. Without ART very few infected people survive beyond ten years.3
Today, a person living in a high-income country who started ART in their twenties can expect to live for another 46 years that is well into their 60s.4
While the life expectancy of people living with HIV/AIDS in high-income countries has still not reached the life expectancy of the general population, we are getting closer to this goal.5
ART prevents new HIV infections
There is considerable evidence to show that people who use ART are less likely to transmit HIV to another person.7 ART reduces the number of viral particles present in an HIV-positive individual and therefore, the likelihood of passing the virus to another person decreases.
We need to increase ART coverage
