- The most common way to get HIV or AIDS is by having sex with someone who has it. But there are other ways, too.
- AIDS is caused by a virus called HIV.
- If you've got AIDS, your body finds it harder and harder to fight off infections.
How Is HIV Passed From One Person to Another?
People get HIV through contact with body fluids that come from someone who has it. The most common ways that someone can get HIV are by:
- Having sex (anal, vaginal, or oral) with a person who has HIV without using a condom
- Sharing drug needles or other drug equipment with someone who has HIV
- Using the same needle as someone with HIV when you get a tattoo
Women with HIV can pass it to their babies before or during birth, and through breastfeeding.
Do Only Gay People Get HIV?
You don't have to be gay to get an HIV infection. You can get HIV from having sex -- without a condom -- with someone of the opposite sex.
How Can I Avoid Getting HIV?
The best way to avoid getting HIV is to not have sex. If you do have sex, you can protect yourself with these steps:
- Always use a condom when having sex.
- Exclusively have sex with one person who is not infected.
- Do not use alcohol or drugs. That way you can make smart choices based on clear thinking.
Activities like hugging, kissing, and rubbing against one another don't spread HIV as long as there are no open sores being touched. Also, you can't give yourself HIV by masturbating.
Can Latex Condoms Prevent HIV?
When used consistently and correctly, they're very good at stopping the spread of HIV during sex. But condom use can't give you perfect protection.
If either partner is allergic to latex, try plastic (polyurethane) condoms. You can get them for both men and women.
Can I Get HIV From Oral Sex?
Yes, it's possible -- whether you're giving or getting oral sex. While no one knows exactly how risky it is, evidence suggests it has less of a risk than unprotected anal or vaginal sex.
You should use protection for oral sex, too: A latex condom on a man, and a latex barrier between a woman's vagina and their partner's mouth. This barrier could be a natural rubber latex sheet, a dental dam, or a cut-open condom that makes a square. In a pinch, you can even use plastic food wrap.
Can I Get HIV From Anal Sex?
Yes. In fact, anal sex without a condom is very risky behavior. Either sex partner can become infected with HIV.
When you have anal sex, use a latex condom. They're more likely to break during anal than vaginal sex, so also use a lot of water-based lubricant to lower the chance of that happening.
Can I Get HIV From Getting a Tattoo?
Yes, if the person who gives you the tattoo uses the same needle that was used on someone who has HIV. That's because any activity that can result in blood getting passed from one person to another carries a risk of HIV infection.
Can I Get HIV From Someone Sneezing on Me or From Touching Someone's Used Tissue?
No. HIV is not passed on in sweat, saliva, or tears. Some other things to know:
- Body fluids that contain the highest concentration of HIV are blood, semen, vaginal fluid, breast milk, and other fluids that contain blood.
- You can't catch it from casual contact like you can a cold or the flu.
- Holding hands or touching someone's skin won't cause you to get the virus.
- Sharing a drinking glass with someone does not spread the virus.
- Open mouth (French) kissing is very low risk for getting the virus unless there are open sores in the mouth or there is blood present.
How Can I Tell if I Have HIV? Are There Symptoms?
Many people who have HIV don't have any symptoms at all for many years. The only way to know if you're infected is to get tested.
Don't wait for symptoms to show up. If you find out you're infected soon after it happens, you'll have more options for treatment and care to help prevent you from getting sick.
How Do I Get Tested for HIV?
Most often, a technician or doctor will draw blood from your vein and check it to see if there are antibodies for HIV. You can also test other body fluids -- oral fluid (not saliva, collected from your mouth using a special device) or urine -- but these aren't as sensitive or accurate as traditional blood tests. Some rapid screening tests can give results in 20-60 minutes.
Current blood tests can find both antibodies and a part of the virus itself. These could give a positive result as soon as 3 weeks after HIV exposure.
Home testing kits found at drugstores are really home collection kits. You prick your finger with a special device, place drops of blood on a specially treated card, and then mail the card in for testing at a licensed lab.
If any of these screening tests say you're positive, follow up with a doctor and more testing to confirm it.
Where Can I Get an HIV Test?
The best thing to do is talk to your health care provider. They will:
- Determine whether or not you should be tested
- Explain the testing procedure
- Describe your options for testing
- Help you locate the nearest testing site
Common places for testing include your local health department, a clinic, your doctor's office, a hospital, and other sites set up specifically for HIV testing.
You can also check www.aids.gov or gettested.cdc.gov, or call 800-CDC-INFO (800-232-4636) 24 hours a day to find somewhere close to you. The call is confidential.
How Long Should I Wait to Get Tested for HIV?
Most people will develop enough antibodies to test positive within 2 to 8 weeks after they're exposed to the virus. The average is 20 days to 25 days. Even so, there's a chance it could take longer. If you think you've been exposed and your HIV test within the first 3 months was negative, get another test at 6 months. If you think you are infected, however, see a doctor right away. They can help guide you in the testing.
If I Decide to Get a Test, Does the Person I Had Sex With Need Testing, Too?
The test will tell you only about yourself. Your sexual partner could still have HIV, even if your test is negative.
Why Should All Pregnant Women Get Tested for HIV?
HIV-positive mothers who get treatment during pregnancy have a much lower chance of passing HIV to their baby before, during, or after birth.
The sooner you start treatment, the more effective it is.
If I’m Younger Than 18, Do I Have to Tell My Parents I Want to Get Tested?
That depends on where you are. In some states, you need your parents’ permission before you can get a test.
Most clinics are confidential. No one else will be told about your test results. You can call a clinic before going there to find out what its policy is on keeping your test confidential.
It's a good idea, though, to talk with an adult you trust about your concerns. A trusted adult can help you sort through your options. The adult can also help you think about your behavior and what to do about behavior that puts you at risk.
What if I Test Positive for HIV?
Prompt, early medical treatment and a healthy lifestyle can help you stay well. We have more and better treatments today, and people are living longer and with a better quality of life than ever before. In fact, depending on what else is going on with their health, HIV-infected persons who get on and stay on their medicines can expect to live almost as long as people who don’t have HIV.
You'll need to keep your doctor's appointments, take your HIV medicines exactly as directed, and take steps so others don't get the virus from you.
How Long Does It Take for HIV to Cause AIDS?
Before HIV medicines became available, Scientists used to think that about half the people with HIV developed AIDS within 10 years after they were infected. However, current drug therapies have dramatically changed the outlook for people living with HIV. If you start HIV medicines early in the course of your infection, keep your medical appointments, and stay on your medicines, you may never develop HIV-related illnesses.
What Happens if I Get AIDS?
When you get infected with HIV, your body's immune system gets weaker. The immune system is what makes your body able to fight off infection and disease.
It takes time for this to happen. But when it does, it can lead to AIDS and be fatal.
While people can die quickly once they develop AIDS, HIV infections can be treated. It's possible with the right treatment to live a long, healthy life.
