China is fuelling a global surge in mpox cases, accounting for the majority of new cases reported in September, according to the World Health Organization. The number of weekly cases reported globally increased by 328% in the week to 10 September, data shows. Most of that rise came from China, where more than 500 new cases were reported in August. The WHO said China was experiencing “sustained community transmission” of the virus, which was first detected as an imported case in September last year. Mpox was previously known as Monkeypox but renamed by the WHO in 2022 in an effort to help tackle discrimination and stigma.
