Gonorrhoea is a sexually transmitted infection (STI) caused by bacteria called Neisseria gonorrhoeae or gonococcus. It used to be known as "the clap". The bacteria are mainly found in discharge from the penis and vaginal fluid from infected men and women.

Gonorrhoea is easily passed between people through: unprotected vaginal, oral or anal sex sharing vibrators or other sex toys that haven't been washed or covered with a new condom each time they are used

The bacteria can infect the cervix (entrance to the womb), the urethra (tube that carries urine out of the body), the rectum and, less commonly, the throat or eyes. The infection can also be passed from a pregnant woman to her baby.

Gonorrhoea is not spread by kissing, hugging, sharing baths or towels, swimming pools, toilet seats, or sharing cups, plates and cutlery, because the bacteria can't survive outside the human body for long.
