No antibiotic-resistant strains of gonorrhea have been detected on the Chinese mainland, which has long been covered by a nationwide surveillance system targeting varied kinds of sexually transmitted diseases, a senior specialist said.

Wang Xiaochun, director of hepatitis C and STD prevention for the National Center for AIDS and STD Control and Prevention, made the remarks following media reports of an untreatable "superbug" gonorrhea, recognized as HO41, hitting countries such as the United States and Japan.

"China for a long time has had a sound surveillance system for STDs such as gonorrhea and syphilis across the mainland, and related drug resistance is also covered by the system," Wang said on Wednesday.
