Primary gonorrhea infection - Anogenital in
The incubation period of N gonorrhoeae is short. The average time from infection to symptom onset is approximately 2-7 days. Risk factors for acquiring N gonorrhoeae include having a new sex partner, more than one sex partner (or a sex partner with concurrent partners), and a history of STIs (or a sex partner with a history of STIs). Other risk factors include inconsistent condom use (if not in a mutually monogamous relationship), young age, and substance abuse. Some subgroups of men who have sex with men (MSM) are at higher risk as well.
The endocervical canal is the most common site of infection in women. Symptoms typically include dysuria, vaginal discharge, bleeding, and menstrual pain. Pelvic inflammatory disease (PID) occurs in 20% of patients as a result of ascending endocervical infection. Clinical features of PID include lower abdominal and adnexal pain, fever, and leukocytosis. Rarely, PID can cause further peritoneal and hepatic inflammation, leading to right upper quadrant pain and gonorrheic perihepatitis (Fitz-Hugh-Curtis syndrome). Chronic untreated PID may lead to tubal scarring with resultant infertility or ectopic pregnancy.
Proctitis and pharyngitis occurs in both sexes via direct mucosal infection, but the former is more prevalent in MSM.
Systemic symptoms including fever, arthritis, tenosynovitis of large joints, and cutaneous pustules can occur from hematogenous dissemination. This occurs in less than 1% of patients. Risk factors for dissemination include menstruation and complement deficiency.
