    Most Common STDs for Women and Men


    HIV is the virus that causes AIDS. It's passed through body fluids such as blood, semen, vaginal fluids, and breast milk. You can get it by having vaginal or anal intercourse with an infected person without a condom, or by sharing a needle with someone who is infected. You can't get HIV from saliva or by kissing.

    Symptoms of HIV infection are vague. They can feel like the flu, with muscle aches, fatigue, or a slight fever. You could also lose weight or have diarrhea. The only sure way to tell if you've been infected is to get your saliva or blood tested.

    HIV can take years to destroy your immune system. Past a certain point, your body loses its ability to fight off infections. There's no cure for AIDS, but powerful drugs can help people with HIV/AIDS live long lives.
