How Do I Avoid Getting Hiv During Sex
HIV is spread through contact with blood or sexual fluids , usually during vaginal and anal sex. So the only 100% certain way to avoid HIV is to not have vaginal or anal sex.
But most people do have sex at some point in their lives, so learning about HIV prevention and knowing how to have safer sex is important. Using condoms REALLY lowers your risk of getting HIV. If youre going to have sex, using condoms every single time is the best way to protect yourself from HIV. Theres also a daily pill you can take called PrEP that can help prevent HIV. Your doctor or nurse can tell you if PrEP is right for you.
Some sexual activities are safer than others when it comes to getting HIV. These activities are no risk theyve never caused a reported case of HIV:
-
masturbating
-
having oral sex with a condom or dental dam
-
using clean sex toys
These activities are lower risk theyve only caused a few reported cases of HIV :
-
“French or deep kissing
-
vaginal sex with a condom and/or PrEP
-
anal sex with a condom and/or PrEP
-
oral sex without a condom or dental dam
These activities are high risk millions of people get HIV this way:
Theres no vaccine that protects against HIV, but lots of people are working on making one. And there are medicines that can help prevent HIV.
The Aids Epidemic Arises
Though HIV arrived in the United States around 1970, it didnt come to the publics attention until the early 1980s.
In 1981, the Centers for Disease Control and Prevention published a report about five previously healthy homosexual men becoming infected with Pneumocystis pneumonia, which is caused by the normally harmless fungus Pneumocystis jirovecii. This type of pneumonia, the CDC noted, almost never affects people with uncompromised immune systems.
The following year, The New York Times published an alarming article about the new immune system disorder, which, by that time, had affected 335 people, killing 136 of them. Because the disease appeared to affect mostly homosexual men, officials initially called it gay-related immune deficiency, or GRID.
Though the CDC discovered all major routes of the diseases transmissionas well as that female partners of AIDS-positive men could be infectedin 1983, the public considered AIDS a gay disease. It was even called the gay plague for many years after.
In September of 1982, the CDC used the term AIDS to describe the disease for the first time. By the end of the year, AIDS cases were also reported in a number of European countries.
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.

Contaminated Blood Transfusions And Organ/tissue Transplants
- receiving blood transfusions, blood products, or organ/tissue transplants that are contaminated with HIV. This risk is extremely small because most countries test blood products for HIV first.
If adequate safety practices are not in place, healthcare workers can also be at risk of HIV from cuts made by a needle or sharp object with infected blood on it. However, the risk of occupational exposure, is very low in most countries.
If you think you have been exposed to HIV, the only way to find out if you have HIV is to have an HIV test.
Tattoos And Body Piercings
- There are no known cases in the United States of anyone getting HIV this way.
- However, it is possible to get HIV from tattooing or body piercing if the equipment used for these procedures has someone elses blood in it or if the ink is shared. This is more likely to happen when the person doing the procedure is unlicensed because of the potential for unsanitary practices such as sharing needles or ink.
- If you get a tattoo or a body piercing, be sure that the person doing the procedure is properly licensed and that they use only new or sterilized needles, ink, and other supplies.

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 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.

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.
Social changes and urbanization
Colonialism in Africa
This theory was later dubbed “Heart of Darkness” by Jim Moore, alluding to the book of the same title written by Joseph Conrad, the main focus of which is colonial abuses in equatorial Africa.
Are There Other Theories About How The Virus Could Have Gotten Into Humans
There are several competing theories, ranging from implausible conspiracies to arguments grounded in extensive research. The best-known of the latter, the “OPV/AIDS” theory, was exhaustively detailed in the 1999 book The River, by author Edward Hooper. As many as a million Africans were given oral polio vaccines between 1957 and 1960. Hooper says witnesses have told him that a few batches of those vaccines were “grown” in chimp cells at a lab in Kisangani, a city in the Democratic Republic of the Congo — and that the chimp cells, and thus the vaccines, could have contained SIVs that jumped into humans. “There are highly significant correlations between the places where this vaccine was administered and the places where ⦠AIDS first appeared on the planet four to 20 years later,” Hooper says.
The majority of HIV researchers subscribe to the bushmeat theory and raise several arguments against the OPV theory. Hahn’s recent research confirming that HIV-1 M and N arose from Pan troglodytes troglodytes chimps in Cameroon presents one problem: The Kisangani lab is in the Democratic Republic of the Congo, and it’s home to a different subspecies of chimp than the one that was the source of HIV-1 M and N. However, it is possible that the chimps used in the Kisangani experiments were not from the area. In the spring of 2006, Hooper found a paper indicating that at least one of eight chimps at the Kisangani lab was a Pan troglodytes troglodytes.

Feels He Contracted Hiv From A Partner Who Was Not Aware Of Their Hiv Infection
All I could do is replay in my mind how I had contracted HIV. I was seeing my partner for nearly a year and he wasn’t aware that he had it. I had been tested yearly and was fine until February of 2000. By July of that year I was infected and by late August I had gotten mononucleosis but it still didn’t occur to me that anything was wrong until my partner began showing symptoms of shingles and his doctor told him it was very strange for him to be in his early thirties and have shingles. He was told that he should be tested for HIV and when he found out he was positive then I instinctively knew I had contracted it as well.
Some people felt they could pin point the incident where they got HIV. Some of these people said that drugs, alcohol or psychological difficulties played a part in their risky sex at the time.

Did Hiv Come From Monkeys
In 1999, researchers found a strain of SIV 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
The same scientists then conducted more research into how SIV could have developed in the chimps. They discovered that the chimps had hunted and eaten two smaller species of monkeys . These smaller monkeys infected the chimps with two different strains of SIV.
The two different SIV strains then joined together to form a third virus that could be passed on to other chimps. This is the strain that can also infect humans.4

A Brief History Of The Epidemic In America
HIV was first identified in 1981 and is the cause of one of the most deadly and persistent epidemics in human history.
The identification of the virus began with rare lung infections and rare and unusually aggressive cancers in young gay men in New York and California. By December 1981, doctors found these same symptoms in five infants whose mothers were drug users and sex workers.
In 1992, AIDS became the number one cause of death for men in the U.S. aged 2544. By 1995, there were 500,000 reported cases of AIDS in the country. However, in 1996 the number of new AIDS cases declined for the first time since the epidemic began.

A Sharp Decline In Hiv/aids Chimpanzee Research
When Jeroms infected blood failed to induce any significant illness in the other three chimpanzees, it served as a wake-up call to researchers using chimpanzees for HIV research. A drop in the number of HIV protocols with chimpanzees followed.
This line of research decreased dramatically from where it was at its peak of roughly 30 studies per year in 1998 to just four in 2005 and three in 2006-2007.
Who Was Patient Zero
The first verified case of HIV derives from a 1959 blood sample of an individual who lived in the Democratic Republic of Congo. However, scientists cannot say whether this person was the first human with HIV, or the first documented case, known as patient zero.
There are numerous documented cases before this one in which the patterns surrounding death suggest HIV as the cause. However, there is no way to prove this through a blood sample. The 1959 sample is the first recorded case in which a blood sample can confirm HIV infection but may not be the first official emergence of HIV.
For many years, Gaétan Dugas was presumed patient zero in the U.S., originally termed patient O for outside Southern California. He was a flight attendant suspected of picking up HIV in Africa or Haiti and bringing it back to the U.S., transmitting it to dozens of men before his death.
However, an analysis into genetics in 2016 found that the viral strain Dugas had was already spreading among men in New York before he began visiting the citys gay bars. This means that Dugas was not the initial individual with HIV. It seems he was an early case but was by no means the first.
There is limited actual knowledge on how the epidemic entered the U.S. because of the challenges in tracing HIV to one individual.

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.
