Causes & Health Information

Some Basics...
- A sexually transmitted disease (STD) is an infection that is spread through vaginal, anal, or oral sex. It is also sometimes called a sexually transmitted infection (STI).
- Examples of STDs include chlamydia, gonorrhea, genital herpes, HIV, pubic lice, and trichomonas.
- Some STDs can be cured with antibiotics (gonorrhea, chlamydia).
- Some STDs cannot be cured, but the symptoms can be reduced (herpes, HIV) by taking prescription medications.
- Condoms are the only effective way to prevent STDs during sex. Condoms can also be used during oral sex to prevent STDs.
How Are STDs Spread?
- Most STDs are spread by body fluids during vaginal, anal, and oral sex. Semen, blood, and vaginal fluids can all spread STDs. Gonorrhea, chlamydia, and trichomonas are spread this way.
- STDs can also be spread through contact with sores during sex. Herpes is spread this way.
- A latex condom works well to stop STDs from spreading during sex.
How Can a Person Avoid Getting an STD?
There are only two 100% effective means of avoiding STDs:
- Not having sex or oral sex (abstinence)
- Having one long-term sexual partner who does not have any STDs
There are some activities that do not spread STDs. These include holding hands, hugging, and touching. Kissing is usually safe. Make sure there are no sores on the lips or in the mouth. Touching semen during mutual masturbation is generally safe.
What Things Don't Work to Prevent an STD?
- Douching the vagina or taking a shower after sex does not prevent STDs.
- Withdrawal is not a way to prevent STDs or pregnancy. This is when a man pulls his penis out before he ejaculates.
- A person can get an STD more than once. Being treated for an STD will not prevent someone from getting it again.
- Using birth control pills, patches, or shots will not prevent you from getting an STD. A condom is still needed.
