STDs and Travel

An estimated 20% of travelers say that they have had casual sex with a new partner while in a foreign country.1 The excitement of being on vacation may encourage people to do things they would not do at home, and the inhibition-lowering effects of drugs and alcohol can also contribute to this behavior. Travelers who have casual sex, whether vaginal, anal, or oral sex, are at risk for sexually transmitted diseases (STDs), such as HIV, herpes, and gonorrhea. Many STDs are treatable, but preventing an STD is always best.

What are the symptoms of an STD?

If you have had unprotected sex, talk to your doctor about getting tested for STDs. Make sure to have an open and honest conversation with your doctor about your sexual history so he or she can determine the appropriate STD test(s) for you. Although most STDs don’t show signs or symptoms, some possible signs of an STD include the following:

  • Pain when you urinate or have sex.
  • Discharge from the vagina, penis, anus, or throat.
  • Unexplained rash or lesion.
  • Jaundice (yellow color of the skin and eyes).

What do I do if I think I have an STD?

Treating STDs early is important to prevent more serious and long-term complications. If you think you have an STD:

  • Stop having sex.
  • See a doctor immediately.
  • Tell the doctor about recent international travel (since some STDs may be more common in other countries).
  • Notify your recent sex partners if your doctor diagnoses an STD.
