Knowing your risk can help you make important decisions to prevent exposure to HIV. The CDC has developed the HIV Risk Reduction Tool to help you know risk and for better understanding of how different prevention methods like using condoms or taking PrEP, can reduce your risk. Overall, an American has a 1 in 99 chance of being diagnosed with HIV at some point in his or her lifetime. However, the lifetime risk is much greater among some populations. If current diagnosis rates continue the lifetime risk of getting HIV is:
1 in 6 for gay and bisexual men overall
1 in 2 for African American gay and bisexual men
1 in 4 for Hispanic gay and bisexual men
1 in 11 for white gay and bisexual men
1 in 20 for African American men overall
1 in 48 for African American women overall
1 in 23 for women who inject drugs
1 in 36 for men who inject drugs
CDC estimates that there are approximately 19 million new sexually transmitted disease (STD) infections each year — almost half of them among young people 15 to 24 years of age. Most infections have no symptoms and often go undiagnosed and untreated, which may lead to severe health consequences, especially for women.
Knowing your STD status is a critical step to stopping STD transmission. If you know you are infected you can take steps to protect yourself and your partners. Many STDs can be easily diagnosed and treated. If either you or your partner is infected, both of you may need to receive treatment at the same time to avoid getting re-infected.
Risks for HIV
The most common ways HIV is transmitted in the United States is through anal or vaginal sex or sharing drug injection equipment with a person infected with HIV. Although the risk factors for HIV are the same for everyone, some racial/ethnic, gender, and age groups are far more affected than others.

What puts me at risk for Hepatitis A
Hepatitis A is usually spread when a person ingests fecal matter — even in microscopic amounts — from contact with objects, food, or drinks contaminated by the feces or stool of an infected person. Due to routine vaccination of children, Hepatitis A has decreased dramatically in the United States. Although anyone can get Hepatitis A, certain groups of people are at higher risk, including men who have sex with men, people who use illegal drugs, people who travel to certain international countries, and people who have sexual contact with someone who has Hepatitis A.

What puts me at risk for Hepatitis B
Hepatitis B is usually spread when blood, semen, or another body fluid from a person infected with the Hepatitis B virus enters the body of someone who is not infected. This can happen through sexual contact with an infected person or sharing needles, syringes, or other drug-injection equipment. Hepatitis B can also be passed from an infected mother to her baby at birth.
Among adults in the United States, Hepatitis B is most commonly spread through sexual contact and accounts for nearly two-thirds of acute Hepatitis B cases. Hepatitis B is 50–100 times more infectious than HIV.

What puts me at risk for Hepatitis C
Hepatitis C is usually spread when blood from a person infected with the Hepatitis C virus enters the body of someone who is not infected. Today, most people become infected with the Hepatitis C virus by sharing needles or other equipment to inject drugs. Hepatitis C was also commonly spread through blood transfusions and organ transplants prior to the early 1990’s. At that time, widespread screening of the blood supply began in the United States, which has helped ensure a safe blood supply.

Risks for Genital Herpes
Genital herpes is a common STD, and most people with genital herpes infection do not know they have it. You can get genital herpes from an infected partner, even if your partner has no herpes symptoms. There is no cure for herpes, but medication is available to reduce symptoms and make it less likely that you will spread herpes to a sex partner.

Risks for Genital Human Papillomavirus (HPV)
HPV is so common that most sexually active people get it at some point in their lives. Anyone who is sexually active can get HPV, even if you have had sex with only one person. In most cases, HPV goes away on its own and does not cause any health problems. But when HPV does not go away, it can cause health problems like genital warts and cancer. HPV is passed on through genital contact (such as vaginal and anal sex). You can pass HPV to others without knowing it.

Risks for Chlamydia
Most people who have chlamydia don’t know it since the disease often has no symptoms. Chlamydia is the most commonly reported STD in the United States. Sexually active females 25 years old and younger need testing every year. Although it is easy to cure, chlamydia can make it difficult for a woman to get pregnant if left untreated.
More information: http://www.cdc.gov/std/chlamydia/the-facts/default.htm
Risks for Gonorrhea
Anyone who is sexually active can get gonorrhea, an STD that can cause infections in the genitals, rectum, and throat. It is a very common infection, especially among young people ages 15-24 years. But it can be easily cured. You can get gonorrhea by having anal, vaginal, or oral sex with someone who has gonorrhea. A pregnant woman with gonorrhea can give the infection to her baby during childbirth.
More information: http://www.cdc.gov/std/Gonorrhea/STDFact-gonorrhea.htm
Risks for Syphilis
Any sexually active person can get syphilis. It is more common among men who have sex with men. Syphilis is passed through direct contact with a syphilis sore. Sores occur mainly on the external genitals, anus, or in the rectum. Sores also can occur on the lips and in the mouth. A pregnant women with syphilis can give the infection to her unborn baby.

Risks for Bacterial Vaginosis
BV is common among women of childbearing age. Any woman can get BV, but women are at a higher risk for BV if they have a new sex partner, multiple sex partners, use an intrauterine device (IUD), and/or douche.
More information: http://www.cdc.gov/std/BV/STDFact-Bacterial-Vaginosis.htm
Risks for Trichomoniasis
Trichomoniasis is a common STD that affects both women and men, although symptoms are more common in women. You can get trichomoniasis by having vaginal sex with someone who has it. Women can acquire the disease from men or women, but men usually contract it only from women.

Your life matters and staying healthy is important. It’s important for you, the people who care about you, and your community. Knowing your HIV status gives you powerful information to help you take steps to keep you and your partners healthy. You should get tested for HIV, and encourage your partners to get tested too. For people who are sexually active, there are more tools available today to prevent HIV than ever before. The list below provides a number of ways that you can lower your chances of getting HIV. The more of these actions you take, the safer you can be.
- Get tested and treated for other STDs and encourage your partners to do the same. All adults and adolescents from ages 13-64 should be tested at least once for HIV and high-risk groups get tested more often. STDs can have long-term health consequences. They can also increase your chance of getting HIV or transmitting it to others. It is important to have an honest and open talk with your healthcare provider and ask whether you should be tested for STDs. Your healthcare provider can offer you the best care if you discuss your sexual history openly. Find an HIV/STD testing site.
- Choose less risky sexual behaviors. Oral sex is much less risky than anal or vaginal sex for HIV transmission. Anal sex is the highest-risk sexual activity for HIV transmission. If you are HIV-negative, insertive anal sex (topping) is less risky for getting HIV than receptive anal sex (bottoming). Sexual activities that do not involve the potential exchange of bodily fluids carry no risk for getting HIV (e.g., touching).
- Use condoms consistently and correctly.
- Reduce the number of people you have sex with. The number of sex partners you have affects your HIV risk. The more partners you have, the more likely you are to have a partner with HIV whose viral load is not suppressed or to have a sex partner with a sexually transmitted disease. Both of these factors can increase the risk of HIV transmission.
- Talk to your doctor about pre-exposure prophylaxis (PrEP). CDC recommends that PrEP be considered for people who are HIIV-negative and at substancial risk for HIV. For sexual transmission, this includes HIIV-negative persons who are in an ongoing relationship with an HIV-positive partner. It also includes anyone who 1) is not in a mutually monogamous* relationship with a partner who recently tested HIV-negative, and 2) is a gay or bisexual man who has had anal sex without a condom or been diagnosed with an STD in the past 6 months; or heterosexual man or woman who does not regularly use condoms during sex with partners of unknown HIV status who are at substantial risk of HIV infection (e.g., people who inject drugs or have bisexual male partners). For people who inject drugs, this includes those who have injected illicit drugs in the past 6 months and who have shared injection equipment or been in drug treatment for injection drug use in the past 6 months. See more information at http://www.cdc.gov/hiv/basics/prep.html
- Talk to your doctor right away (within 3 days) about post-exposure prophylaxis (PEP) if you have a possible exposure to HIV. An example of a possible exposure is if you have anal or vaginal sex without a condom with someone who is or may be HIV-positive, and you are HIV-negative and not taking PrEP. Your chance of exposure to HIV is lower if your HIV-positive partner is taking antiretroviral therapy (ART) consistently and correctly, especially if his/her viral load is undetectable (see Can I transmit HIV if I have an undetectable viral load). Starting medicine immediately (known as post-exposure prophylaxis, or PEP) and taking it daily for 4 weeks reduces your chance of getting HIV.
- If your partner has HIV, encourage your partner to get into care and to take HIV medicine as prescribed. Taking HIV medicine as prescribed can make the level of virus in their body very low (called viral suppression) or even undetectable. A person with HIV who gets and stays virally suppressed or undetectable can stay healthy and has effectively no risk of transmitting HIV to HIV-negative partners through sex.
* Mutually monogamous means that you and your partner only have sex with each other and do not have sex outside the relationship.
The best way to prevent both Hepatitis A and B is by getting vaccinated. There is no vaccine available to prevent Hepatitis C. The best way to prevent Hepatitis C is by avoiding behaviors that can spread the disease, such as sharing needles or other equipment to inject drugs.
The only way to avoid STDs is to not have vaginal, anal, or oral sex. If you are sexually active, you can do several things to lower your chances of getting an STD, including:
- Get tested for STDs and encourage your partner(s) to do the same. It is important to have an honest and open talk with your healthcare provider and ask whether you should be tested for STDs. Your healthcare provider can offer you the best care if you discuss your sexual history openly. Find an STD testing site.
- Get vaccinated. Vaccines are safe, effective, and recommended ways to prevent hepatitis A, hepatitis B, and HPV.
- Be in a sexually active relationship with only one person, who has agreed to be sexually active only with you.
- Reduce your number of sex partners. By doing so, you decrease your risk for STDs. It is still important that you and your partner get tested, and that you share your test results with one another.
- Use a condom every time you have vaginal, anal, or oral sex. Correct and consistent use of the male latex condom is highly effective in reducing STD transmission.
Persons who have an STD are at least two to five times more likely than uninfected persons to acquire HIV infection if they are exposed to the virus through sexual contact. In addition, if a person who is HIV positive also has an STD, that person is more likely to transmit HIV through sexual contact than other HIV-infected persons.
Hepatitis B virus (HBV) and HIV are bloodborne viruses transmitted primarily through sexual contact and injection drug use. Because of these shared modes of transmission, a high proportion of adults at risk for HIV infection are also at risk for HBV infection. HIV-positive persons who become infected with HBV are at increased risk for developing chronic HBV infection and should be tested. In addition, persons who are co-infected with HIV and HBV can have serious medical complications, including an increased risk for liver-related morbidity and mortality.
Hepatitis C Virus (HCV) is one of the most common causes of chronic liver disease in the United States. For persons who are HIV infected, co-infection with HCV can result in a more rapid occurrence of liver damage and may also impact the course and management of HIV infection.
