Public health officials in England have raised alarms about a surge in antibiotic-resistant gonorrhoea cases, warning that the infection could become 'untreatable' if the trend of rising antibiotic resistance continues. New data from the UK Health Security Agency indicates an increase in antibiotic-resistant gonorrhoea cases. The rise in ceftriaxone-resistant gonorrhoea is alarming because ceftriaxone is the primary antibiotic used to treat gonorrhoea. Health authorities have issued repeated warnings about rising cases of gonorrhoea and other STIs in England, urging anyone who has had condomless sex with a new or casual partner to get tested. Gonorrhoea is a disease caused by the bacterium Neisseria gonorrhoeae, which can cause major problems if left untreated.
