How Can You Prevent HIV?
Anyone can get HIV, but there are more tools today to prevent HIV than ever before.
Get Tested and Know Your Partner’s HIV Status
Talking to your partner(s) about HIV testing and getting tested before sex are great first steps in understanding your risk. To better understand your own potential risk for HIV, talk to your doctor or use this interactive tool from the CDC.

Assess Risks Involved With Sexual Activities
Sex is the primary way that HIV passes from person to person. Condoms and/or medications can reduce this risk. If you are not taking PrEP regularly or do not have a condom available, you may want to discuss other types of sex with your partner(s).
- Receptive anal sex is the type of sex most likely to increase your chances of acquiring HIV. While it is possible for either partner (the top or the bottom) to acquire HIV during anal sex, it is much more likely for an HIV-negative receptive partner (bottom) to acquire HIV when having anal sex with a person who is living with undiagnosed or untreated HIV. This is because the lining of the rectum is thin and micro-tears may allow HIV to enter the body during anal sex. Though it is less likely for receptive partner (bottom) to pass HIV to the penetrative partner (top), HIV may still enter the body through the penis via small cuts, scratches, or other open sores.
- Vaginal sex is less likely than anal sex (and more likely than oral sex) to increase your chances of acquiring HIV. While it is possible for either partner to acquire HIV during vaginal sex, it is much more likely for an HIV-negative person with a vagina to acquire HIV when vaginal sex with a person who is living with undiagnosed or untreated HIV. This is because the tissue lining the vagina may tear during intercourse and these tears allow HIV to enter the body during sex. Though it is less likely for a penetrative partner (partner with a penis) to acquire HIV wile having vaginal sex, HIV may still enter the body through the penis via small cuts, scratches, or other open sores.
- Oral sex (e.g. fellatio, cunnilingus, and anilingus) and touching (frottage) are the sexual activities least likely to cause HIV acquisition. Partners should be aware of gum bleeding, open sores in or on the mouth, and open sores on the penis, anus, or vagina when engaging in these types of sexual activities.
Use Insertive or Receptive Condoms
While abstaining from sex and/or limiting the number of your partners greatly reduces your potential for acquiring HIV, there are several tools you can use as part of your HIV prevention strategy.
- Insertive condoms, sometimes known as male condoms, are highly effective in preventing HIV and some STIs when used correctly. Water and silicone-based lubricant can be used during sex to prevent condom breakage and tearing of tissue.
- Receptive condoms, sometimes known as female condoms, are also highly effective in preventing HIV and some STIs when used correctly. Receptive condoms can be used internally by people who have vaginal or anal sex. Like insertive condoms, water and silicone-based lubricants can also be used during sex to prevent condom breakage and tearing of tissue.
- Condoms and dental dams (latex or polyurethane sheets used between the mouth, vagina, or anus during oral sex) are effective in preventing HIV and some STIs when used correctly during oral sex.

Taking Medicine To Prevent Or Treat HIV
In the Living with HIV section, you can learn more about how people living with HIV (PLHIV) are using medications to manage their health and treat their HIV. Many PLWH who take their medications as prescribed are able to achieve viral suppression, meaning that they have no detectable HIV in their blood. When there is no detectable HIV viral load in your body you have no risk of sexually transmitting the virus. This is commonly known as Undetectable = untransmittable or U=U. For more information check out this fact sheet developed by the Centers for Disease Control.
Pre-Exposure Prophylaxis (PrEP)
Pre-exposure prophylaxis (PrEP) are medications that can be taken in advance (orally or injected) to protect someone from acquiring HIV from sex or needle sharing. If taken consistently and as prescribed by your provider, PrEP can reduce your risk of acquiring HIV by over 90%. You can find more information on accessing PrEP in Iowa at PrEP Iowa.
Post-Exposure Prophylaxis (PEP)
If you have a recent potential exposure to HIV, a doctor can prescribe medications to reduce your chances of acquiring HIV. Post-exposure prophylaxis (PEP or nPEP) must be started within 72 hours of a potential exposure (and is more effective the earlier it is started).
If you need PEP/nPEP contact your doctor, visit your nearest emergency room, or reach out the Iowa PrEP/PEP navigator for assistance.
Safer Substance Use
Some forms of substance use can increase your risk related to HIV. Persons who use or inject drugs can reduce their risk by not sharing or re-using substance use equipment.
