All Exposures Are Not Equal
The results of several meta-analyses suggest that some types of sex carry on average a higher risk of HIV transmission than others. Below are estimates from meta-analyses that have combined the results of studies conducted in high-income countries. For types of sex where meta-analysis estimates do not exist, numbers from individual studies are provided.
A meta-analysis exploring the risk of HIV transmission through unprotected anal sex was published in 2010.1 The analysis, based on the results of four studies, estimated the risk through receptive anal sex to be 1.4%. This risk was similar regardless of whether the receptive partner was a man or woman.
No meta-analysis estimates currently exist for insertive anal sex but two individual studies were conducted to calculate this risk. The first, published in 1999, calculated the risk to be 0.06% .2 However, due to the design of the study, this number likely underestimated the risk of HIV transmission. The second study, published in 2010, was better designed and estimated the risk to be 0.11% for circumcised men and 0.62% for uncircumcised men.3
A meta-analysis of 10 studies exploring the risk of transmission through vaginal sex was published in 2009.4 It is estimated the risk of HIV transmission through receptive vaginal sex to be 0.08% .
A meta-analysis of three studies exploring the risk from insertive vaginal sex was estimated to be 0.04% .4
Preventing Hiv Among Sex Workers
Access to HIV prevention services for sex workers in still too low. In 2017 it was estimated that 1 million sex workers in east and southern Africa did not have access to HIV prevention services, with coverage as low as 38% in South Sudan increasing to 74% in Kenya.48
Sex work is diverse and occurs in various contexts around the world. Although some sex workers sell sex through brothels or other venues, others might work independently and solicit clients directly in public places or online.
Effective HIV prevention packages for sex workers are those that account for the contexts in which they work and the particular risks they face.49
In order to address the high burden of HIV sex workers face, UNAIDS recommends the following:
- address the violence against sex workers
- empower sex work communities
- scale-up and fund health and social services for sex workers50:
UNAIDS also emphasises the importance of combining HIV prevention strategies for sex workers, including integrating condom distribution with other HIV services and increasing links between HIV services and other sexual and reproductive health services such as family planning services, gynaecological services and maternal health.51
Despite this, in 2015 just 3.8% of total global spending on prevention was used to fund prevention programmes for sex workers. The vast majority of this funding was supplied by international donors. fn]UNAIDS ‘Prevention Gap Report’
Is There A Cure For Hiv
There is no cure for HIV. But if you acquire the virus, there are drugs that help suppress the level of HIV in the body and prevent its spread to other people. Doctors use a combination of drugs called HAART to treat HIV/AIDS. Although it is not a cure, HAART has greatly reduced the number of deaths from HIV-related complications in the United States. HIV has become like a chronic disease, and people living with HIV receiving successful treatment can live a long and healthy life.

How Is Hiv Transmitted Through Sex
HIV can be transmitted through semen, vaginal secretions, blood, and anal secretions. When a person doesnt use a condom during sex, its easier for semen, vaginal fluids, blood, and anal secretions to enter their body either being absorbed across the mucous membrane of the vagina or anus or entering the bloodstream directly.
Anal sex is a known risk factor for contracting HIV if other prevention methods are absent, especially for the receptive partner whose anus is being penetrated by the penis.
Vaginal sex can also lead to HIV transmission if other prevention methods are absent, especially for the receptive partner whose vagina is being penetrated by the penis.
Both anal and vaginal sex can also carry a risk of HIV transmission for the insertive partner .
Oral sex is thought to be very low risk. Rimming is also thought to very low risk.
How Hiv Is Transmitted
HIV is not passed on easily from one person to another. The virus does not spread through the air like cold and flu viruses.
HIV lives in the blood and in some body fluids. To get HIV, 1 of these fluids from someone with HIV has to get into your blood.
The body fluids that contain enough HIV to infect someone are:
- vaginal fluids, including menstrual blood
- breast milk
- contact with animals or insects like mosquitoes

Isnt Hiv Only A Risk For Certain Groups Of People
Like most illnesses, HIV doesnt discriminate between types of people and the infection can be passed on to anyone via one of the ways mentioned above.
Some people are more vulnerable to HIV infection if they engage regularly in certain activities that are more likely to transmit the virus. However, its a common misunderstanding that HIV only affects certain groups.
While not everyone has the same level of HIV risk, everyone can reduce their risk of infection.

If I Already Have Hiv And Then I Get An Std Does That Put My Sex Partner At An Increased Risk For Getting Hiv
It can. If you already have HIV, and then get another STD, it can put your HIV-negative partners at greater risk of getting HIV from you.
Your sex partners are less likely to get HIV from you if you
- Get on and stay on treatment called antiretroviral therapy . Taking HIV medicine as prescribed can make your viral load very low by reducing the amount of virus in your blood and body fluids. HIV medicine can make your viral load so low that a test cant detect it . If your viral load stays undetectable, you have effectively no risk of sexually transmitting HIV to HIV-negative partners, even if you have other STDs.
- Choose less risky sex activities.
- Use a new condom, consistently and correctly, for every act of vaginal, anal, and oral sex throughout the entire sex act .
The risk of getting HIV also may be reduced if your partner takes PrEP medications, as prescribed, after discussing this option with his or her healthcare provider and determining whether it is appropriate. When taken as prescribed, PrEP medications are highly effective for preventing HIV from sex. PrEP is much less effective if it is not taken consistently. Since PrEP does not protect against other STDs, use condoms the right way every time you have sex.

Why Does Heroin Use Create Special Risk For Contracting Hiv/aids And Hepatitis B And C
Heroin use increases the risk of being exposed to HIV, viral hepatitis, and other infectious agents through contact with infected blood or body fluids that results from the sharing of syringes and injection paraphernalia that have been used by infected individuals or through unprotected sexual contact with an infected person. Snorting or smoking does not eliminate the risk of infectious disease like hepatitis and HIV/AIDS because people under the influence of drugs still engage in risky sexual and other behaviors that can expose them to these diseases.
People who inject drugs are the highest-risk group for acquiring hepatitis C infection and continue to drive the escalating HCV epidemic: Each PWID infected with HCV is likely to infect 20 other people.21 Of the 30,500 new HCV infections occurring in the United States in 2014, most cases occurred among PWID.22
Hepatitis B infection in PWIDs was reported to be as high as 25 percent in the United States in 2014,22 which is particularly disheartening since an effective vaccine that protects against HBV infection is available. There is currently no vaccine available to protect against HCV infection.
Chances Of Getting Hiv From One Encounter
You have unprotected sex with someone from the opposite sex, just that once.
You realize later that the person is HIV positive, meaning that he/she is infected with the HIV .
You want to know what are the odds of you getting infected from exposure with that single unprotected encounter.
You could also have a blood transfusion once or share an injection needle with an infected partner just that once. What are the chances of contracting this viral disease?
The odds vary and depend on a few factors.

Effective Treatments Can Reduce Hiv Transmission
When someone with HIV is on antiretroviral treatment and consistently has very low levels of virus they are not infectious and cannot sexually transmit the virus.
This may be true for sexual transmission during pregnancy, but researchers are still gathering more evidence before they can be confident it is true for transmission during pregnancy, labour and delivery, and during breastfeeding.
As long as the HIV-positive partner maintains a stable undetectable viral load and these medications are taken strictly as prescribed, HIV transmission to a negative partner is not possible.
Speak to your treating doctor if you would like to explore these newer prevention drugs.
We Know That Men Who Have Sex With Men In Illinois Are At Higher Risk For Hiv What About Women Who Have Sex With Women
It is not a personâs gender, sexual orientation, race or class that puts them at risk for HIV. People are at risk for HIV when they practice risky behaviors. Women who identify as lesbian or gay can be at risk for HIV by practicing any of the behaviors that place women at risk. Lesbian women have become infected with HIV by using injection drugs or having unprotected sex with male or female partners who are already infected with HIV. Women who have sex with other women should follow guidelines in this fact sheet to protect themselves, and can call the Illinois AIDS/HIV/STD Hotline at 800-243-AIDS for specific information.

How Is Hiv Transmitted
Anyone, at any age, can get HIV. People usually acquire HIV from unprotected sex with someone living with HIV, through contact with HIV-infected blood, or by sharing needles with a person living with HIV. You may be at risk if:
- You had sex without a latex or polyurethane condom. The virus passes from the person living with HIV to his or her partner via blood, semen, or vaginal fluid. During sex, HIV can get into your body through body fluids and any opening, such as a tear or cut in the lining of the vagina, vulva, penis, rectum, or rarely the mouth. Latex condoms can help prevent HIV transmission between sexual partners.
- You or your sexual partners have shared needles with a person living with HIV. People who inject illegal drugs are not the only people who might share needles. For example, people with diabetes who inject insulin or draw blood to test glucose levels could also share needles. Talk to your partner about their drug and sexual history, and always use a new, sterile needle for injections.
- You had a blood transfusion or operation in a developing country at any time.
- You had a blood transfusion in the United States between 1978 and 1985.
- You were diagnosed with or treated for hepatitis or tuberculosis at any time.
How Common Is Mother
In the UK all pregnant women are offered an HIV test, because transmission can now be easily prevented.
Once its known that the mother-to-be is living with HIV, shell be put on treatment right away. The doctors will instruct her on how to protect the baby during pregnancy, delivery and once the baby is born. Shell also be advised not to breast feed and the baby will be given a course of HIV treatment.
Thanks to those strategies theres now less than 1% chance of the baby having HIV. This falls to 0.1% if the mother is on treatment with an undetectable viral load. Back when those interventions were not known and commonly used, the risk of transmission was 30-45%.

Male Vs Female Partners
When having vaginal sex without a condom with a partner who has a penis, the vaginal membranes are more likely to tear than the partners penis.
In condomless anal sex with a partner who has a penis, the rectal membranes are also more likely to tear than the partners penis. Microscopic tears create an easier path for HIV and other STIs to enter the body when exposed.
Its possible for a partner with a penis to contract HIV during vaginal and anal sex. If a female partner is living with HIV with a detectable viral load, it can be carried in her vaginal secretions. If her partner has open sores on their mouth or penis, they can create a gateway for vaginal secretions or other bodily fluids with HIV to enter the body.
Uncircumcised men are at higher risk of contracting HIV from condomless sex than circumcised men. The delicate membranes of foreskin can tear during sex, creating a pathway for HIV to enter the body.
Is There Any Treatment Of A Cure For Hiv/aids
Currently, there is no cure for HIV/AIDS. People living with HIV will need lifelong treatment. The best treatments right now are combinations of prescription drugs. These medications include antiviral treatment, protease inhibitors and other drugs that help people who are living with HIV stay healthy. People living with HIV also can stay healthy by doing things like eating properly, exercising and getting enough sleep.

You’re More Likely To Get Hiv If Your Partner Has Hiv And An Std
People with both HIV and an STD have more HIV in their semen or vaginal fluid. This makes it easier for a person with an STD or HIV to give the virus to others when having sex without a condom.
Remember, many people who have HIV don’t know it. It can take many years for symptoms to show up. That is why it is so important to use condoms during sex, or not to have sex at all.

Performing Oral Sex On A Man With Hiv
Theres a potential risk if an HIV negative person performs oral sex on a man with HIV who has a detectable viral load.
This risk increases if a mans infected pre-cum or semen gets into the other persons mouth.
Avoid getting semen in your mouth all but one of the cases where someone has been infected with HIV through oral sex took place when an HIV positive person with a detectable viral load ejaculated into their mouth.

Challenges In Calculating A Number
It isn’t easy for researchers to calculate the risk of transmission from an exposure to HIV through sex. To do this effectively, a group of HIV-negative individuals need to be followed over time and their exposures to HIVboth the number of times they are exposed and the types of exposureneed to be tracked.
As you can imagine, accurately tracking the number of times a person is exposed to HIV is very difficult. Researchers ask HIV-negative individuals enrolled in these studies to report how many times they have had sex in a given period of time, what type of sex they had, how often they used condoms and the HIV status of their partner. Because a person may have trouble remembering their sexual behaviour or may not want to tell the whole truth, this reporting is often inaccurate.
Furthermore, a person does not always know the HIV status of their partner. For this reason, researchers usually enroll HIV-negative individuals who are in stable relationships with an HIV-positive partner . Researchers can then conclude that any unprotected sex reported by a study participant counts as an exposure to HIV.
