Gonorrhea is a common sexually transmitted infection caused by Neisseria gonorrhoeae. It can affect the genitals, rectum, or throat, and often presents with painful urination, abnormal discharge, or pelvic/testicular pain, though many people have no symptoms. If left untreated, it may lead to serious complications such as pelvic inflammatory disease, infertility, or disseminated infection. Diagnosis is usually made with nucleic acid amplification testing (NAAT), and treatment currently involves a single intramuscular injection of ceftriaxone, with close attention to rising antibiotic resistance. Consistent condom use, routine screening, and partner treatment are important steps in prevention and control.
