For Teens: What You Should Know About HIV and AIDS

HIV is a virus that, in its advanced stages of infection, can cause AIDS. AIDS is a disease that kills by making a person unable to fight off some diseases. There is no cure for HIV infection or for AIDS. But treatment can control HIV/AIDS. And it can prevent dangerous infections. It can also reduce your risk of spreading the infection to others. HIV/AIDS can affect anyone. This includes gay, straight, or bisexual people. It can affect anyone of any gender, race, or ethnic background. HIV is passed from person to person. It's passed through close contact with blood, semen, and vaginal fluid. HIV can also be passed from a pregnant mother to her unborn child or baby during vaginal birth.

How you can get HIV

You can get HIV from:

  • Having sex with a person who is infected with HIV or has AIDS. This includes vaginal or anal sex. It can be sex with someone of the opposite or same sex. But sex between two women is low risk. And sex between men is high risk. It can happen from having sex just once.

  • Sharing infected needles used to inject illegal drugs or steroids.

  • Being exposed to infected needles used for body piercing or tattooing that have not been sterilized well.

  • Sharing infected razors or other sharp items.

How you can't get HIV

You can't get HIV from:

  • Hugging, kissing, sharing food, or shaking hands with someone who has HIV.

  • Oral sex.

  • Toilet seats, doorknobs, tables, or dishes.

  • Insect bites

It’s up to you to protect yourself

Protect yourself from HIV by not having sex unless you use a condom. You can’t tell if people have HIV by the way they look. Are you thinking about having sex? Then be ready to protect yourself. Have the correct protection ready. Stay sober. Using alcohol or drugs can make you lose control. Then you are more likely to have sex without a condom.

Things to consider:

  • You don’t need to have sex to have a great time and get close to someone.

  • Having sex increases your chances of getting HIV and some other diseases.

  • Don’t give in to pressure to have sex. Wait until you’re ready. There are a lot of responsibilities that go along with sex.

If you do have sex, use a latex condom and limit your number of partners:

  • Are you having sex? Then use a condom each time you have sex. Latex male condoms and female condoms both help protect you. Using a latex condom correctly and consistently can help reduce the spread of sexually transmitted infections (STIs), one of which is HIV.

  • Keep latex condoms on hand. Store them in a cool, handy place. Don’t keep them in your wallet or car. This can make the latex break up.

  • Learn how to use condoms correctly.

  • Limit the number of sex partners you have. Don't have casual "hook-ups." People with more sex partners and who have casual "hook-ups" are more likely to get HIV.

  • Always talk with your sex partners about their HIV status. If they don't know, make sure they are tested before you have sex.

  • Get routine STI screening from your health care provider even if you do not have symptoms.

  • If you have symptoms of an STI, get medical care right away. Symptoms may include a discharge, burning, sores, swollen glands, and rash. Having an untreated STI makes it more likely to get others, including HIV.

  • If you may have been exposed by sex to someone with HIV or of unknown HIV status, see a provider as soon as possible within 72 hours. A treatment called PEP (post-exposure prophylaxis) can help prevent getting HIV.

  • If you are having unprotected sex often or have already had an STI, talk with your provider to see if PrEP (pre-exposure prophylaxis) is a good option to prevent getting HIV. PrEP involves taking a medicine regularly to give you extra protection in case you are exposed to the virus.

  • If you are having sex with someone with HIV, find out if they are taking their HIV medicine every day and if the virus in their blood is undetectable (completely under control). If they are not taking their HIV medicines and the virus is detectable, or if you are unsure about this, use condoms every time you have sex. Also, strongly consider taking PrEP. If your partner has HIV, is taking their medicines daily, and their virus is not detected for at least 6 months straight, then the chance of getting HIV from them is small, even without condoms.
