Diagnosis
Your doctor will ask about your symptoms, and sexual and health history. Your doctor will check the pelvic area for signs of infection.
Testing involves:
- Women—testing fluid or discharge from the vagina
- Men—testing urine, semen, or discharge from the penis
A lab will check the samples for the parasite.
Treatment
Antibiotics treat the infection. You should not have sex until you stop treatment and your symptoms are gone.
Part of care involves talking to your sexual partners. They may need healthcare even if they don’t have symptoms.
Prevention
To lower your chances of STIs:
- Always use condoms when you have sex.
- Only have sex with one person.
