Concerns are mounting over a powerful new form of gonorrhoea after a patient was found to have the highest level of drug resistance to the disease ever reported in Australia.
It is understood the patient, a tourist from central Europe, contracted the "sex superbug" in Sydney and was eventually treated in Cairns.
The discovery of the case in Australia, which resulted in a health alert in July, has also prompted warnings in New Zealand, where sexual health clinics are on high alert amid fears the new strain will spread there.
NZ Sexual Health Society president Edward Coughlan warned the patient involved, who is believed to have left the country, had the highest level of gonorrhoea drug resistance ever reported in Australia.
The warning comes amid concern in recent years about an untreatable strain, known as H041, which was first discovered in 2009 after a sex worker fell victim to the superbug in Japan.
