The Chinese mainland recorded 2,291 confirmed COVID-19 cases on Tuesday, with 2,249 attributed to local transmissions and 42 from overseas, data from the National Health Commission showed on Wednesday.

The cumulative number of confirmed cases on the Chinese mainland is 369,918, with the death toll from COVID-19 standing at 5,235.

The commission said that starting on Wednesday, it will no longer report asymptomatic infection data.

"At present, COVID-19 nucleic acid testing is voluntary, and many asymptomatic persons no longer participate in such testing, which makes it impossible to accurately determine the exact number of cases," the authorities explained.
