Gonorrhea is a bacterial infection caused by Neisseria gonorrhoeae that is transmitted through sexual contact. It is estimated that 98 million new cases occur annually worldwide. Common symptoms include abnormal discharge, burning during urination, and pelvic pain. Diagnosis involves testing samples from the affected area. Treatment consists of a single dose of ceftriaxone and azithromycin. Left untreated, gonorrhea can cause pelvic inflammatory disease and increase risk of infertility.
