Several provincial-level regions have reported domestic cases or asymptomatic carriers over the past consecutive days, thus effective personal protection and community-based control and prevention measures should be maintained, said Mi Feng with the National Health Commission, at a press conference.

A total of 89 new confirmed COVID-19 cases were reported on the Chinese mainland on April 13. Among them, 86 were imported cases and three were domestic ones reported in the southern Chinese province of Guangdong.
