Within a matter of weeks, three cases of gonorrhoea that are resistant to the recommended first line antibiotic treatment have been detected in Europe and Australia. These are the first global reports of Neisseria gonorrhoeae with high-level resistance to azithromycin and ceftriaxone resistance that also show resistance to several other vital antibiotics. At a time with limited alternatives to the current dual therapy, lack of a vaccine and insufficient surveillance capacity in some regions, these cases highlight the growing threat of drug-resistance – which could lead to untreatable gonorrhoea.
