Non-gonorrhea, or non-gonococcal urethritis, has an incubation period of about 1-5 weeks and is a disease caused by chlamydial and mycoplasma infections of the genital tract, transmitted mainly through sexual intercourse. Nowadays, the term non-gonorrhea is basically not mentioned anymore and is replaced by Chlamydia trachomatis infection of the genitourinary tract. Patients clinically infected with chlamydia or mycoplasma usually have no obvious specific symptoms in the early stage, and after 1-5 weeks may have symptoms such as painful urination, frequent urination, dripping urination, redness and swelling of the urethra, and some soiling and crusting on the underwear, etc. Men may also develop acute epididymitis with a clear, thin discharge from the urethra. Because the symptoms are mild, patients often ignore them or confuse them with diseases such as urinary tract infection. If there is a history of unclean sexual life or multiple sexual partners at the same time, and there is also discomfort in the urethra or abnormal discharge, you should go to a professional hospital for bacterial culture and antigen antibody examination for early detection and early treatment. It is worth noting that after a patient has been infected with non-gonococcal urethritis, the spouse should also be examined immediately and treated actively, using anti-inflammatory drugs such as tetracycline or quinolones under the guidance of a doctor.
