Gonorrhoea

Gonorrhoea is a common sexually transmitted infection caused by Neisseria gonorrhoeae. It is usually transmitted through vaginal, oral, and anal sex. Gonorrhoea causes different symptoms in women and men. Women often feel no symptoms, but untreated infection can lead to infertility and problems during pregnancy. Gonorrhoea can be passed on to the infant during pregnancy. Gonorrhoea is curable with antibiotics.

In 2025, there were 42,393 gonorrhoea diagnoses in Australia, representing an increase of 78% over 10 years.
