Diagnosis
The doctor will ask about your symptoms and health history. A physical exam will be done.
These tests will be done to look for signs of infection:
- A swab of the penis, cervix, throat, or rectum
- Urine tests
Treatment
Antibiotics are used to treat the infection. A person's sexual partners should also be treated.
Prevention
To lower the risk of this infection:
- Do not have oral, anal, or genital sex.
- Limit sex to one partner.
- Use latex condoms during sex.
