For Teens: Understanding HIV/AIDS

A blood test can show if you have been infected with HIV.

HIV weakens the parts of the body that fight off disease (the immune system). It spreads through body fluids passed during sex, or through infected needles. When HIV starts to cause severe health problems, it’s called AIDS. There’s no cure for HIV or AIDS. But antiretroviral medicines can help control the infection. This treatment lets your body heal some of the damage and stay healthier longer. Many people with HIV are now living a normal lifespan. That's often the case if the infection is found and treated early.

What to look for

A few weeks after HIV is in the body, most people will have symptoms such as:

  • A lasting fever

  • Sore throat

  • Trouble swallowing

  • Headaches

  • Muscle and joint aches

  • Rash

  • Fatigue

These symptoms may last for a few days to several weeks. They may seem like the flu. So if you’re at risk for HIV, get tested. It’s the only way to know for sure. You can get HIV testing at most health clinics. You can also learn more about testing by calling 800-CDC-INFO (800-232-4636).

Antiretroviral therapy

Antiretroviral therapy is treatment with a number of HIV medicines taken at the same time. These medicines work together to control the virus. They can restore your immune system and prevent future harm to it. An HIV infection can’t be cured. But these medicines can help many people live a normal and active life. .

Antiretroviral therapy can also help stop the spread of the virus to others. It works best if the person with HIV is taking the medicines routinely and has an "undetectable" HIV viral load for at least 6 months. If you have HIV and it's been under control for at least 6 months but you are not taking medicines as directed, you need to practice safer sex to protect others. This means using latex or polyurethane condoms during sex. You also need to tell any sex partners about your HIV. Let them know whether you are taking your medicines as directed and if your virus is under control.

If you don’t get treated

Over time, HIV weakens the immune system and many other parts of the body. This makes it easier for you to get sick. You may have:

  • Diarrhea and weight loss

  • Night sweats and fevers

  • Itchy rash

  • Skin sores (lesions)

  • Memory problems or confusion

  • Swollen glands and white spots in the mouth (thrush)

  • Pain and numbness in the toes and fingers

  • Health problems such as pneumonia, blood infections, brain infection (meningitis), cancers, and kidney failure. Some of these can be life threatening.

Stop HIV

Stop what can be the harmful effects of HIV. If you are at risk for HIV, get tested regularly. Screening is advised for all people ages 15 to 65. People younger and older than that who are at high risk should also be screened.

Take steps to prevent getting or spreading HIV. Practice safe sex. And use pre-exposure prophylaxis (PrEP) and post-exposure prophylaxis (PEP) if needed. These are medicines that help stop the virus from infecting you. If you have HIV, get into care right away and stay in care. Always take your antiretroviral medicines. Use condoms unless your healthcare provider says it's safe not to. And if you are living with HIV, tell your partner. Make sure you are not putting that person at risk.
