What is it?

Gonorrhoea is a sexually transmitted infection caused by bacteria called Neisseria gonorrhoeae. It is the second most common bacterial sexually transmitted infection in the UK.

Gonorrhoea is easily treated. However, if left untreated in women, gonorrhoea can spread to other reproductive organs (the womb and the fallopian tubes), causing long-term pain, blocked tubes, infertility and ectopic pregnancy (this is when a pregnancy develops in the fallopian tube rather than in the womb). If untreated in men, gonorrhoea can cause a painful infection in the testicles and prostate gland.


In April 2016 Public Health England (PHE) issued a statement about a highly drug-resistant type of gonorrhoea with the warning that it may become untreatable.

A powerful strain of the STI, first seen in the north of England, has since been found in the West Midlands and the south-east.

The strain is highly resistant to the antibiotic azithromycin, which means clinicians are relying on a second drug, ceftriaxone, to treat it. However, there are no other effective drugs to tackle the strain, raising the prospect of it becoming untreatable if it builds further resistance.

PHE has urged people to use condoms with new or casual partners to cut the risk of catching the disease. If untreated, gonorrhoea can result in severe complications and in rare cases lead to infertility or septicaemia.

Dr Gwenda Hughes, the head of PHE’s STI section, said: “Fortunately, the current outbreak strain can still be treated with ceftriaxone. Nonetheless, we know that the bacterium that causes gonorrhoea can rapidly develop resistance to other antibiotics that are used for treatment, so we cannot afford to be complacent.

“If strains of gonorrhoea emerge that are resistant to both azithromycin and ceftriaxone treatment options would be limited as there is currently no new antibiotic available to treat the infection.”

By 17 April 2016 there had been 34 confirmed cases since November 2014. Since September 2015, 11 cases had been confirmed in the West Midlands and in the south of England, five of them in London.

At least 16 cases were first detected in northern England, including 12 in Leeds, where the mutated strand was first recorded, PHE said in September 2015.
