Gonorrhoea is a sexually transmitted disease caused by Neisseria gonorrhoeae bacteria. Gonorrhoea is most often acquired through direct mucosal contact during sex, and the bacteria can colonize the genitals, urinary tract, rectum, and throat. From there, the bacteria can enter the eye with infected lymph nodes and cause eye infections in newborns at birth. Infection of the rectum and throat is usually asymptomatic. If symptoms appear, they are usually 1–7 days after infection, but symptoms can develop later.
