We respect your privacy. It takes only one instance of exposure to become infected with the human immunodeficiency virus, or HIV. Here, approximately, are the odds of getting HIV , broken down by type of exposure — and how to reduce your risk. The reason is that needles, syringes, and other equipment can contain blood, and therefore HIV, which can then be directly transmitted into the bloodstream. Under the right environmental circumstances, the virus can survive in a used needle for up to 42 days, according to the U.

Untreated HIV can lead to AIDS, which occurs when the immune system is so weak it becomes susceptible to serious infections and some cancers. An estimated 39, people in the country were diagnosed with HIV in alone. HIV transmission occurs in many different ways, including through condomless sex and by sharing needles. Risk of transmission varies depending on several factors including:. HIV can be transmitted through semen, vaginal secretions, blood, and anal secretions.
HIV can be transmitted to either partner regardless of who is topping or bottoming, especially during anal sex without a condom. These microscopic tears can create a route for HIV-containing fluids, such as semen, to enter the body. 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. There are also different methods of protection during sexual activity including use of pre-exposure prophylaxis PrEP , post-exposure prophylaxis PEP , and treatment as prevention.
PEP refers to taking prescription antiretroviral medications after a recent possible exposure to HIV. Reducing the viral load helps a person with HIV stay healthy, and it also lowers the risk of that person transmitting HIV to a sexual partner. First, some STIs like syphilis and herpes cause ulcers, or sores, to develop in the genital area or mouth. These sores create an opening in the skin, making it easier for HIV to enter the body, if exposed.
Second, when a person has an infection, their immune system sends out certain cells to help fight it. Sharing needles also puts a person at higher risk of contracting HIV. If the needle has already been injected into another person, it can carry traces of their blood, along with any infections they have.
HIV can affect anyone. Whatever their age, gender, sexuality, ethnicity, or race, everyone should take steps to protect themselves. Anyone who thinks they might have contracted HIV needs to get tested immediately. Early treatment can help manage the symptoms, lower the risk of complications, lower the risk of transmitting HIV to a sexual partner, and help people to live a long and healthy life.

For example, antiretroviral therapy ART means that the amount of virus in the blood can now be reduced to undetectable levels. At these levels, it does not harm the body, and it cannot be passed on to another person. In addition, the use of pre-exposure prophylaxis PrEP offers a high level of protection by stopping the virus from passing through the body, even if exposure occurs.
It is a pill that can be taken regularly by those who have a higher risk of exposure. HIV is considered a blood-borne virus. However, touching blood where the virus is present will not lead to transmission. This can only happen if blood that contains the virus enters an open wound. For example, if a person with HIV has an open wound, and fluid from that wound enters an open wound on a person without the virus, HIV can be passed on.
This can happen in the form of needlestick injuries, sharing needles, and tattoos carried out with unclean or used needles. Theoretically, HIV can be passed on during a blood transfusion, but screening practices are strictly implemented, making this highly unlikely nowadays. HIV cannot be transmitted through the following:. The risks of contracting the virus through other methods of exposure, such as biting, scratching, and thrown bodily fluids, are either extremely small or nonexistent.
Today, the blood supply is considered safe, but sharing needles remains a significant source of transmission. In some parts of the world, where infection control measures are not strict, an infant may contract HIV from a source that is not their mother.
In this case, the infant will have the virus but the mother will not. A review of studies published in found that mothers who were breastfeeding infants with HIV had a 40 to 60 percent chance of contracting the virus. Open sores in the mouth can shed the virus into tiny sores on a mother's breast.
Reliably taking anti-retroviral drugs while breastfeeding reduces the risk of transmitting the virus to the infant. Breastfeeding is an important source of nutrition for infants, and there are different recommendations. Any decision should be made after speaking with a doctor.
All these risks can be reduced through increased awareness of and access to antiretroviral therapy, preventive medication, and support services. A range of effective strategies can now lower the risk of having HIV, even among vulnerable groups.
People who have a high risk should take PrEP once every day. Women with HIV who are pregnant or who plan to become pregnant should discuss risk mitigation strategies with their doctors, including the choice of whether or not to breastfeed.
Appropriate use of antiretroviral drugs can reduce to zero the risk of spreading the virus to others, and it can halt or delay viral activity within the body. When the viral load, or amount of virus in the blood, is below copies per milliliter , it is considered undetectable. At this level, it cannot be transmitted to another person. It is important to follow up on medical care to ensure the viral load remains below the detectable level.
Signs that a person has been exposed to the virus may include intense, flu-like symptoms that occur within a month.
Anyone who experiences these symptoms should seek medical help. However, if HIV is the cause, early diagnosis will allow for early treatment. It can protect health and prolong life.
Some people may have the virus but experience no symptoms. Anyone who thinks they may have been exposed to HIV should ask for a test.

Studies show that if used correctly, condoms offer strong protection against HIV, as well as having the added benefit of reducing the risk of other STIs. To best protect against HIV they can be used in combination with other prevention methods such as pre-exposure prophylaxis PrEP or an undetectable viral load.
You can read an overview of condoms here. Laboratory studies and product testing have shown that reputable condoms tested in the laboratory are completely impermeable to micro-organisms as small as viruses. How well do condoms actually work in preventing HIV in the real world? Producing an accurate estimate is difficult for researchers.
One reason for this is that they rely on study participants accurately reporting their use of condoms, frequency of sex and the HIV status of their sexual partners. Two recent analyses are worth highlighting. Analysis found that among those who reported consistently using condoms i. Data were included on a total of participants different inclusion and exclusion criteria were used from the previous analysis. As with the previous paper, the studies relied on the self-reporting of condom use.
An undetectable viral load is the first goal of antiretroviral therapy. Measurement of the amount of virus in a blood sample, reported as number of HIV RNA copies per milliliter of blood plasma.
Why, then, is this higher than the previous estimate? Firstly, the paper analysed condom efficacy across four different studies, whereas the previous estimate resulted from analysis of just two. However, the researchers argue that the key difference between the two studies can be explained by differing methodologies.
While the estimate is based on condom efficacy per sex act, the estimate is based on efficacy per number of partners.
They calculated the risk per extra partner of HIV infection in people sometimes or never using condoms for receptive anal sex, compared to people who always used them.
In people who always used condoms, it only rose by 7. This may be because an HIV-positive partner with a high viral load is likely to transmit in the first few months of a relationship, while a partner with a low viral load may never transmit HIV. Because there is less risk of infection as time goes on, the risk of not using condoms also diminishes over time — and so, therefore, does their apparent efficacy. On the other hand, if someone continues having sex with multiple partners, their infection risk does not diminish over time because their chances of encountering someone with a high viral load stays constant — as does the efficacy of condoms.
Foteini Giannou and a group of European researchers published a meta-analysis in that examined 25 studies that recruited a total of 10, couples with one HIV-positive and one HIV-negative partner. These studies were done in a range of countries between and In the review, the protective effect of consistent condom use was slightly greater when the male rather than the female partner was HIV positive. There was also geographic variability, with much greater levels of protection reported in two Asian studies than in eleven studies conducted in North and South America.
The researchers comment that this raises questions about social, cultural, biological or methodological differences that are not fully understood. Due to genetic differences, there could be geographic variations in susceptibility to HIV. The evidence therefore shows that while condoms are highly effective against HIV transmission under laboratory conditions, unsurprisingly in the real-world they are not always used perfectly.
This lowers protection levels for both heterosexual and gay couples. Condoms are much less effective if they're used incorrectly. In , Dr Stephanie Sanders of the Kinsey Institute and colleagues published an analysis of 50 studies concerning condom use in 14 countries. In total, between 1. This negates the protective benefits of condoms, since fluids are exchanged throughout intercourse and not just during ejaculation.
Avoiding such mistakes is important to prevent condom breakage and ensure that you are best protected against HIV transmission. For a step-by-step guide on how to use condoms correctly, read our factsheet. Figures for the frequency of condoms breaking, slipping off or leaking vary widely between studies. Up to a third of men report problems with the fit and feel of condoms, which are in turn associated with condoms breaking or slipping off.
Choosing a condom that is an appropriate size for the penis reduces the risk of breakage. We are not aware of similar studies in other populations.
The risk of HIV transmission is zero. However, condoms provide additional benefits in terms of preventing sexually transmitted infections and unwanted pregnancy.
