Institute of Human Anatomy - Why Gonorrhea Could Soon Be Untreatable (And What That Means for You)
Gonorrhea, caused by the bacterium Neisseria gonorrhoeae, is primarily sexually transmitted but can also spread nonsexually. It often goes unreported due to asymptomatic cases, particularly in women, where up to 70% of cervical infections show no symptoms. Symptoms, when present, include vaginal irritation, abnormal discharge, and intermenstrual bleeding in women, and urethral discharge and painful urination in men. Untreated infections can lead to pelvic inflammatory disease (PID) in women, causing infertility or ectopic pregnancies. Gonorrhea can also infect the rectum, throat, and eyes. The primary treatment is the antibiotic ceftriaxone, but resistance is growing, making treatment more challenging. Testing, particularly the nucleic acid amplification test, is crucial for diagnosis and preventing spread. Safe sex practices and public health responsibility are emphasized to control the infection and its resistance.
Key Points:
- Gonorrhea often asymptomatic, especially in women, leading to underreporting and spread.
- Symptoms in women include vaginal irritation and discharge; in men, urethral discharge and pain.
- Untreated gonorrhea can lead to serious complications like PID, infertility, and ectopic pregnancy.
- Ceftriaxone is the main treatment, but antibiotic resistance is increasing, complicating treatment.
- Testing and safe sex practices are crucial to control spread and resistance.
