A man in the UK has caught the world’s “worst-ever” case of super-gonorrhoea.
He had a regular partner in the UK, but picked up the superbug after a sexual encounter with a woman in South East Asia.
Public Health England says it is the first time the infection cannot be cured with first choice antibiotics.
Health officials are now tracing any other sexual partners of the man, who has not been identified, in an attempt to contain the infection’s spread.
He picked up the infection earlier in the year.
The main antibiotic treatment – a combination of azithromycin and ceftriaxone – has failed to treat the disease.
Dr Gwenda Hughes, from Public Health England, said: “This is the first time a case has displayed such high-level resistance to both of these drugs and to most other commonly used antibiotics.”
Discussions with the World Health Organization and the European Centres for Disease Control agree this is a world first.
