How Do I Know If I Have Hiv

Where Did HIV Come From?, Who’s Patient Zero for AIDS?, History of HIV/AIDS

The only way to know for sure if you have HIV is to get tested. Testing is relatively simple. You can ask your health care provider for an HIV test. Many medical clinics, substance abuse programs, community health centers, and hospitals offer them too. You can also buy a home testing kit at a pharmacy or online.

To find an HIV testing location near you, use the HIV Services Locator.

HIV self-testing is also an option. Self-testing allows people to take an HIV test and find out their result in their own home or other private location. You can buy a self-test kit at a pharmacy or online. Some health departments or community-based organizations also provide self-test kits for free.

Read the U.S. Food and Drug Administrations fact sheet on the OraQuick In-Home HIV Test, the only FDA-approved in-home HIV test.

The coronavirus pandemic has made it more difficult for some people to access traditional places where HIV testing is provided. Self-testing allows people to get tested for HIV while still following stay-at-home orders and social distancing practices. Ask your local health department or HIV service organization if they offer self-testing kits.

The Cultural Response To Hiv

Public response was negative in the early years of the epidemic.

In 1983, Dr. Joseph Sonnabend in New York was threatened with eviction for treating people with HIV, leading to the first AIDS discrimination lawsuit.

Bathhouses across the country closed due to sexual activity and the associated risk. Some schools also barred children with HIV from attending.

U.S. blood banks started screening for HIV in 1985, and men who had sex with men were banned from donating blood . first lifted some of its restrictions in December 2015. The FDA loosened its restrictions again in 2020, motivated by the blood shortage caused by COVID-19.)

In 1987, the United States placed a travel ban on visitors and immigrants with HIV.

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.

In 1997, researchers calculated that this resistance accounted for .

The number of avoidable transmissions may be even higher.

A 2005 study looked at people in New York City who used injectable drugs and had been admitted to a drug detoxification program. The researchers concluded that the legalization of syringe exchange programs helped reduce HIV prevalence among this group from 50 percent in 1990 to 17 percent in 2002.

Strategies For Preventing The Transmission Of Hiv

  • Abstain from sexual activity.

  • Use a latex condom for each act of intercourse with an infected partner or a partner whose HIV status is unknown .

  • For men engaging in oral sex, withdraw before ejaculation.

  • For men, get circumcised .

  • For newly monogamous couples, get tested for HIV infection and other sexually transmitted diseases before engaging in unprotected sexual intercourse.

  • Never share needles or syringes.

  • Wear rubber gloves when touching body fluids of another person .

  • If accidentally exposed to fluids containing HIV , seek treatment with antiretroviral drugs to prevent infection.

Condoms made of latex provide good protection against HIV , but they are not foolproof. Oil-based lubricants should not be used because they may dissolve latex, reducing the condoms effectiveness.

Other measures can help. For men, circumcision, an inexpensive, safe procedure, reduces the risk of becoming infected during vaginal intercourse with an infected woman by about half. Whether circumcision reduces the risk of HIV infection in other circumstances is unclear. Because circumcision provides only partial protection against HIV infection, people should also use other measures to prevent HIV infection. For example, if either partner has a sexually transmitted disease or HIV infection, it should be treated, and condoms should be used correctly and consistently.

What Are The Causes Of Kidney Disease

Diabetes and high blood pressure are the leading causes of kidney disease. Other factors that increase the risk of kidney disease include heart disease and a family history of kidney failure.

A persons risk of kidney disease increases as they get older. The longer a person has diabetes, high blood pressure, or heart disease, the greater their risk of kidney disease.

The risk of kidney failure is especially high among African Americans, Hispanics, and American Indians, partially because these communities have high rates of diabetes and high blood pressure.

Where Did Hiv/aids Come From

PPT

Where does HIV come from in the first place? HIV is a virus that likely originated in monkeys and apes in Africa. One theory says that HIV started as a virus that infected these animals. The virus later changed into a form that was able to infect humans. The disease may have started infecting humans more than 100 years ago. There was an HIV pandemic in Congo in the 1920s. The virus then made its way to the population of Haiti in the 1960s. It later emerged in the United States and other countries first and became very prevalent in the 1980s.

Tracing The Origin Of Hiv

There exists an overwhelming amount of evidence to suggest that HIV arose from cross-species transmission of closely related viruses that are found naturally in various primate hosts in Africa.

By looking at the genomes of these viruses, which are collectively known as simian immunodeficiency viruses , and comparing them with those of the different types of HIV we can see that the SIVs are the closest relatives of HIV. Furthermore, geographical correlations exist between SIVs in their different hosts and HIV.

HIV-1 and HIV-2 have different origins as they arose from independent transmission events. Closely related SIVs have been found in monkeys called sooty mangabeys in Western Africa, which is the only region that HIV-2 is endemic in. Therefore, scientists conclude that HIV-2 has its origins in SIV infected sooty mangabeys.

HIV-1 is a little more complicated, but each different group arose from a single transmission event. M and N have been traced back to SIV infected chimpanzees , but the closest relatives of O and P have been found in gorillas.

How Do You Get Hiv

HIV is carried in semen , vaginal fluids, anal mucus, blood, and breast milk. The virus gets in your body through cuts or sores in your skin, and through mucous membranes . You can get HIV from:

  • having vaginal or anal sex

  • sharing needles or syringes for shooting drugs, piercings, tattoos, etc.

  • getting stuck with a needle that has HIV-infected blood on it

  • getting HIV-infected blood, semen , or vaginal fluids into open cuts or sores on your body

HIV is usually spread through having unprotected sex. Using condoms and/or dental dams every time you have sex and not sharing needles can help protect you and your partners from HIV. If you do have HIV, treatment can lower or even stop the chances of spreading the virus to other people during sex. If you dont have HIV, theres also a daily medicine called PrEP that can protect you from HIV.

HIV can also be passed to babies during pregnancy, birth, or breastfeeding. A pregnant woman with HIV can take medicine to greatly reduce the chance that her baby will get HIV.

HIV isnt spread through saliva , so you CANT get HIV from kissing, sharing food or drinks, or using the same fork or spoon. HIV is also not spread through hugging, holding hands, coughing, or sneezing. And you cant get HIV from a toilet seat.

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 LĂ©opoldville , 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.

How Can I Protect Myself

The best way to protect yourself from HIV is to not have sex and not share needles.

If you decide to have sex, reduce your risk of getting HIV by:

Understanding how HIV spreads can help you make safer choices about sex. Talk to your doctor if you have any questions about HIV and if you want to get tested.

What Are The Symptoms Of Kidney Disease

Kidney disease can advance very slowly. Slowly worsening kidney disease is called chronic kidney disease.

As kidney disease gets worse, a person may have swelling of the legs, feet, or ankles . Symptoms of advanced chronic kidney disease can include:

  • Increased or decreased urination
  • Feeling tired or having trouble sleeping
  • Nausea and vomiting
  • Itching or numbness

Blood and urine tests are used to detect kidney disease. Care for people with HIV includes testing for kidney disease.

How Do You Get Or Transmit Hiv

You can only get HIV by coming into direct contact with certain body fluids from a person with HIV who has a detectable viral load. These fluids are:

  • Blood
  • Semen and pre-seminal fluid
  • Rectal fluids
  • Vaginal fluids
  • Breast milk

For transmission to occur, the HIV in these fluids must get into the bloodstream of an HIV-negative person through a mucous membrane open cuts or sores or by direct injection.

People with HIV who take HIV medicine daily as prescribed and get and keep an undetectable viral load have effectively no risk of sexually transmitting HIV to their HIV-negative partners.

Hiv/aids In The 1990s And 2000s

How and where does AIDS come from?

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.

Samples Collected From Wildlife In Thailand

While its true that most emerging diseases affecting humans come from wildlife, its often human behavior that is to blame for the spillover. Humans are tearing down forests and hunting, eating, and selling wild animals at unprecedented rates. Each exotic animal shipped across the ocean to be sold as a pet is an sveacasino opportunity for a new pathogen to take root in a new continent. Each tree ripped from its roots increases interactions between humans and wild animals, and thus the odds that viruses will find new populations to infect.

But the good news is: If were the ones causing the problem, were the ones who can stop it.

Looking Back And Moving Forward

In 2021, AIDS turned 40 while the world was immersed in another pandemic. It helped shed light on the tremendous scientific progress we made in understanding, treating, and preventing HIV. A virus that was once a death sentence is now a chronic manageable condition. While there is no cure, with care and treatment as directed by a healthcare provider, people living with HIV can live longer, healthier lives.28,29

Now we must all focus our attention on reducing HIV discrimination and disparities and helping break the barriers to equitable care so that those most in need have access to these advancements in prevention and care.

Symptoms Of Hiv Infection

Most people experience a short flu-like illness 2 to 6 weeks after HIV infection, which lasts for a week or 2.

After these symptoms disappear, HIV may not cause any symptoms for many years, although the virus continues to damage your immune system.

This means many people with HIV do not know they’re infected.

Anyone who thinks they could have HIV should get tested.

Some people are advised to have regular tests as they’re at particularly high risk.

Origin of HIV, or Where Does HIV Come From?

The first published report of what would ultimately become known as HIV and AIDS appeared in the Centers for Disease Control and Prevention Morbidity and Mortality Weekly Report in June 1981.1 When these initial cases emerged, very little was known about the disease it did not have an agreed-upon name, researchers had not yet determined what caused it, there were no tests or recognized treatments, and by the time most patients presented with symptoms, they had only months to live.2

In the United States, where the disease was first seen in already marginalized communitiesincluding men who have sex with men , people who inject drugs, and people who exchange sex for moneythe public and policymakers were slow to respond to this new health threat.3-5

The history of the HIV epidemic highlights amazing scientific discovery and fierce advocacy in the face of adversity, but it also shows stigma, discrimination, and disparities based on race, sexual orientation, and socioeconomic status. There is hope as scientific advancements have turned HIV from a death sentence to a manageable chronic condition, but there is still neither a cure nor a vaccine.2

Who Is The First Person Infected By Hiv

A human case of HIV is first documented in the Congo when a man died there and his preserved blood samples later confirmed he had HIV infection. A 49-year-old Haitian shipping clerk, Ardouin Antonio, died of Pneumocystis carinii pneumonia, a disease that is closely associated with AIDS, in New York City on June 28.

Can Hiv Be Spread Through Casual Contact

How does HIV transmission occur? It is not possible to get HIV from an infected person with whom you have casual contact. You can’t get HIV from hugging, shaking hands, a toilet seat, a drinking fountain, or by eating food prepared by a person who is HIV-positive. You cannot get HIV from a bug bite. You cannot contract the virus from tears, saliva, sweat, or closed-mouth kissing. HIV dies quickly when it is on surfaces outside of the human body.

    PPT

    HIV can only be spread through specific activities. In the United States, the most common ways are:

    • Having vaginal or anal sex with someone who has HIV without using a condom or taking medicines to prevent or treat HIV. Anal sex is riskier than vaginal sex.
    • Sharing injection drug equipment , such as needles, with someone who has HIV.

    Less common ways are:

    HIV is spread only in extremely rare cases by:

    • Having oral sex. But in general, the chance that an HIV-negative person will get HIV from oral sex with an HIV-positive partner is extremely low.
