A sexually transmitted disease caused by a bacteria (Neisseria gonorrhoea).
In men this causes a discharge of pus from the penis due to inflammation of the urethra (the tube inside the penis through which urine passes).
In women it can infect all the pelvic organs, cause collections of pus in them and chronic pain. Damage to the fallopian tubes which connect the ovaries to the womb (uterus) can result in eggs starting to develop in the tubes instead of in the womb. This is called an ectopic pregnancy and it can kill the mother (deaths from that are counted under maternal conditions, U042). A normal pregnancy can end with the eyes of a baby, born to a mother with gonorrhoea, becoming infected. Untreated this can cause scarring of the eye, resulting in blindness or low vision. However gonorrhoea infection often makes it difficult to get pregnant and it is a common cause of infertility.
Gonorrhoea caused 0.002% of all deaths worldwide in 2002 with an average of 0.2 deaths per million people, not including deaths due to ectopic pregnancy.
