HIV and AIDS
How Do People Get HIV?
A person gets HIV when an infected person's body fluids (blood, semen, fluids from the vagina or breast milk) enter his or her bloodstream. The virus can enter the blood through linings in the mouth, anus, or sex organs (the penis and vagina), or through broken skin.
Both men and women can spread HIV. A person with HIV can feel OK and still give the virus to others. Pregnant women with HIV also can give the virus to their babies.
Common ways people get HIV:
- Sharing a needle to take drugs
- Having unprotected sex with an infected person
You cannot get HIV from:
- Touching or hugging someone who has HIV/AIDS
- Public bathrooms or swimming pools
- Sharing cups, utensils, or telephones with someone who has HIV/AIDS
Who Can Get HIV?
Anyone can get HIV if they engage in certain activities. You may have a higher risk of getting HIV if you:
Have unprotected sex. This means vaginal or anal intercourse without a condom or oral sex without a latex barrier with a person infected with HIV.
Share needles to inject drugs or steroids with an infected person. The disease can also be transmitted by dirty needles used to make a tattoo or in body piercing.
Receive a blood transfusion from an infected person. This is very unlikely in the U.S. and Western Europe, where all blood is tested for HIV infection.
Are born to a mother with HIV infection. A baby can also get HIV from the breast milk of an infected woman.
If you fall into any of the categories above, you should be tested for HIV. In fact, the U.S. Preventive Services Task Force (USPSTF) recommends that everyone ages 15 to 65 should be tested, as well as all pregnant women.
Health care workers are at risk on the job and should take special precautions. Some health care workers have become infected after being stuck with needles containing HIV-infected blood, or less frequently, after infected blood comes into contact with an open cut or through splashes into the worker's eyes or inside his or her nose.
