Sexually Transmitted Diseases/Infections

A sexually transmitted disease (STD) is an infection caused by bacteria or a virus. It is also known as a sexually transmitted infection. STDs are spread by oral, genital, or anal sex. Some examples of STDs are chlamydia, syphilis, and gonorrhea. HIV and viral hepatitis are the most common sexually transmitted infections.

If you are sexually active, getting tested for STDs is one of the most important things you can do to protect your health. Make sure you have an open and honest conversation about your sexual history and STD testing with your doctor and ask whether you should be tested for STDs. If you are not comfortable talking with your regular health care provider about STDs, there are many clinics that provide confidential and free or low-cost testing.

Below is a brief overview of STD testing recommendations.

  • All adults and adolescents from ages 13 to 64 should be tested at least once for HIV.
  • AAnnual chlamydia screening of all sexually active women younger than 25 years, as well as older women with risk factors such as new or multiple sex partners, or a sex partner who has a sexually transmitted infection.
  • AAnnual gonorrhea screening for all sexually active women younger than 25 years, as well as older women with risk factors such as new or multiple sex partners, or a sex partner who has a sexually transmitted infection.
  • ASyphilis, HIV, chlamydia, and hepatitis B screening for all pregnant women, and gonorrhea screening for at-risk pregnant women starting early in pregnancy, with repeat testing as needed, to protect the health of mothers and their infants.
  • AScreening at least once a year for syphilis, chlamydia, and gonorrhea for all sexually active gay, bisexual, and other men who have sex with men (MSM). MSM who have multiple or anonymous partners should be screened more frequently for STDs (i.e., at 3-to-6 month intervals).
