Chlamydial infections - Anogenital in
Patients are infected during sexual intercourse, when the urethra or rectum is inoculated with the organism. Pharyngeal infection is also possible.
The incubation period is 7-14 days. Many patients infected are asymptomatic. Symptoms can vary depending on the location of the infection. Patients with urethritis may complain of dysuria or urethral pruritus. Epididymitis presents with epididymal pain (usually unilateral) and sometimes fever. Proctitis presents with rectal pain and discharge (sometimes bloody). Lymphogranuloma venereum (LGV) is a disease caused by certain serovars of C. trachomatis. Symptoms include severe proctocolitis with rectal discharge, pain, and fever. Tender inguinal lymphadenopathy may also be seen (the "groove sign").
Coinfection with other sexually transmitted diseases (STDs), including gonorrhea, is common.
Some patients may develop reactive arthritis.
