Gonorrhoea
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 in vaginal fluid.
Gonorrhoea is easily passed between people through:
- unprotected vaginal, oral or anal sex
- sharing vibrators or other sex toys that have not been washed or covered with a new condom each time they're used
The bacteria can infect the entrance to the womb (cervix), the tube that passes urine out of the body (urethra), the rectum and, less commonly, the throat or eyes.
The infection can also be passed from a pregnant woman to her baby. If you're pregnant and may have gonorrhoea, it's important to get tested and treated before your baby is born.
Without treatment, gonorrhoea can cause permanent blindness in a newborn baby.
Gonorrhoea is not spread by kissing, hugging, swimming pools, toilet seats, or sharing baths, towels, cups, plates or cutlery. The bacteria cannot survive outside the human body for long.
Symptoms of gonorrhoea
Typical symptoms of gonorrhoea include a thick green or yellow discharge from the vagina or penis, pain when urinating and, in women, bleeding between periods.
However, around 1 in 10 infected men and almost half of infected women do not experience any symptoms.

Getting tested
If you have any of the symptoms of gonorrhoea, or you're worried you may have an STI, you should visit your local sexual health clinic for a sexual health test.

You can also contact the FPA sexual health helpline on 0345 122 8687.
Gonorrhoea can be easily diagnosed by testing a sample of discharge picked up using a swab. In men, testing a sample of urine can also diagnose the condition.
It's important to get tested as soon as possible because gonorrhoea can lead to more serious long-term health problems if it's not treated, including pelvic inflammatory disease (PID) in women or infertility.

Treating gonorrhoea
Gonorrhoea is usually treated with a single antibiotic injection and a single antibiotic tablet. With effective treatment, most of your symptoms should improve within a few days.
It's usually recommended you attend a follow-up appointment a week or two after treatment so another test can be carried out to see if you're clear of infection.
You should avoid having sex until you've been told you no longer have the infection.
Previous successful treatment for gonorrhoea does not make you immune to catching it again.

Who's affected?
Anyone who's sexually active can catch gonorrhoea, particularly people who change partners frequently or do not use a barrier method of contraception, such as a condom, when having sex.
Gonorrhoea is the second most common bacterial STI in the UK after chlamydia. In 2017, more than 44,500 people were diagnosed with gonorrhoea in England, with most cases affecting young men and women under the age of 25.
Preventing gonorrhoea
Gonorrhoea and other STIs can be successfully prevented by using appropriate contraception and taking other precautions, such as:
- using male condoms or female condoms every time you have vaginal sex, or male condoms during anal sex
- using a condom to cover the penis or a latex or plastic square (dam) to cover the female genitals if you have oral sex
- not sharing sex toys, or washing them and covering them with a new condom before anyone else uses them
If you're worried you may have an STI, visit your local GUM or sexual health clinic for advice.
