Gonorrhea is a sexually transmitted disease caused by the infection of Neisseria gonorrhoeae, also known as gonococcus, primarily manifesting as purulent infections of the urinary and reproductive organs. The main route of transmission for gonorrhea is through sexual contact, but it can also be transmitted through close living contact and from mother to child. The clinical symptoms of gonorrhea vary; symptoms in males are typically more pronounced, including frequent urination, urgent urination, painful urination, and redness and swelling at the urinary opening, which may exude yellow purulent discharge. In females, the symptoms of gonorrhea are generally milder, commonly affecting the cervix and vagina with mucous secretions initially, which may later become purulent, often without significant noticeable symptoms.
