Debunking 13 Common HIV Myths


Two Roche HIV experts answer some common misconceptions about the virus.

December 1, 2022


In the 1980s, human immunodeficiency virus (HIV) and acquired immunodeficiency syndrome (AIDS) became an epidemic. Now 40 years later, HIV is still an issue. With sexual trends continuing to change in the United States, younger generations are more at risk. Two Roche Diagnostic HIV experts, Tamar Tchelidze, M.D., MPH, disease area partner, and Benjamin LaBrot, M.D., global medical affairs manager, debunk 13 myths around HIV.


Myth 1: HIV is no longer an issue.


There are over 36,000 new HIV infections in the U.S. every year and over 18,000 deaths. In 2020, almost 60% of all new diagnoses occurred in people ages 13 to 34 – and nearly 40% of new diagnoses were in people ages 25 to 34. As young people increasingly engage in less protected sexual activity and more risky sexual practices, HIV heavily impacts them. HIV is still very much with us – it has become a forgotten disease, but the disease has not forgotten us.


Myth 2: Having HIV means getting AIDS.


Absolutely not. With the current antiretroviral treatment, most people do not get AIDS. They live long, healthy lives.


Myth 3: There's no way to prevent HIV.


There are many ways to prevent HIV. Not engaging in vaginal or anal sex, not sharing needles when injecting drugs, practicing safer sex with condoms, finger cots and dental dams, and using Pre-Exposure Prophylaxis, known as PrEP all help in preventing the spread of HIV. If taken when HIV-free, Pre-Exposure Prophylaxis – a medication in the form of pills or injections – significantly reduces the chance of getting HIV from sex or injection drug use.


Myth 4: HIV is a “gay disease.”


Anyone can get HIV. In 2020, almost a quarter of all new HIV infections occurred through heterosexual encounters. While the disease is currently more prevalent among men who have sex with men, anyone who has sex is at risk of HIV. Newer sexual trends may place straight people more at risk as anal sex – a riskier form of sex for HIV transmission – has gained popularity.


Myth 5: Straight people don't participate in anal sex.


Heterosexual anal intercourse (HAI) has become more typical, with more than 3 in 10 people reporting having HAI. A survey question from the Centers for Disease Control's National Survey of Family Growth showed that about 38% of women said they had anal sex with a different sexual partner in 2017 to 2019, compared to 33% in 2015 to 2017. Men stayed consistent at about 38%.

Women ages 25 to 29 reported in 2015 to be the population most actively engaging in anal receptive sex in the past month, according to the most recent data available from the 2015 Sexual Exploration in America Study survey.


Myth 6: You can't get HIV from oral or vaginal sex.


Although the risk of getting HIV from oral sex is extremely low, you absolutely can get HIV from vaginal sex. About 7,000 women in the U.S. get infected with HIV annually, many from unprotected vaginal intercourse.


Myth 7: Birth control prevents the spread of HIV.


With the exception of condoms, most birth control methods such as oral contraceptives and IUDs prevent only pregnancy, not HIV or other sexually transmitted infections. Pre-Exposure Prophylaxis, known as PrEP, is the best HIV prevention option currently available, offering over 95% protection. Condoms, and to a lesser extent finger cots and dental dams, also help prevent the spread of HIV but aren't as effective as PrEP.


Myth 8: Straight people who don't use drugs delivered by needles can't get HIV.


However someone identifies, anyone who has unprotected vaginal or anal sex absolutely can contract HIV and a slew of other diseases as well, including hepatitis, gonorrhea, syphilis and even Zika. Injecting drugs and sharing needles add even more risk.

Those who have unprotected sex are at high risk – similar to risks for other sexually transmitted diseases – and having receptive anal sex is the riskiest type of sex for getting or transmitting HIV.


Myth 9: If I have one partner or if I trust my partners, I should not worry about getting HIV.


Even when you trust your partner, getting routine HIV testing can assure you are both disease free.

Current studies of American couples indicate that 20% to 40% of straight married men and 20% to 25% of straight married women will also have an extramarital affair during their lifetime, and polyamorous individuals have amplified risk. It is important to be able to trust your partner or partners, but also important not to forget about human nature.


Myth 10: Having HIV means taking medicine every day.


There are many ways to prevent HIV. Some include taking a daily oral medication, but many others include long-acting injections and avoiding high-risk activities such as unprotected vaginal or anal sex or sharing needles. New protection options are constantly developing, including twice-yearly injections, patches and other ideas to make it easier and more convenient.


Myth 11: It's OK to have unprotected sex if both partners have HIV.


This is a common misconception. There are many different strains of HIV, and some respond better to treatment than others. In fact, many strains now are showing more resistance to the drugs we rely on to treat HIV. A person with HIV can contract additional, more severe strains of HIV from another infected person.


Myth 12: I can get HIV from mosquitoes.


No, this is an urban legend. There are many diseases that mosquitoes can transmit, but thankfully HIV is not one of them.


Myth 13: You can get HIV from a toilet seat, swimming pool or sharing utensils.


No, this is a common myth about HIV, but HIV transmission requires direct contact between two peoples' bodily fluids. You simply cannot contract it from a toilet seat or swimming pool, and to date, there are no known cases where sharing utensils (or even spitting in someone's mouth) resulted in contracting HIV, as HIV does not live well in saliva. HIV in the U.S. is transmitted almost exclusively through unprotected anal and vaginal sex and sharing needles when injecting drugs.
