BEIJING — The number of existing confirmed COVID-19 cases on the Chinese mainland had dropped for 11 consecutive days as of May 2, a Chinese health official said on May 3.

The mainland reported 12 new asymptomatic cases on May 2, the lowest figure since the daily report on COVID-19 cases included this figure, said Mi Feng, a spokesperson for the National Health Commission, at a press conference in Beijing.

However, 10 provincial-level regions had reported new locally transmitted cases or asymptomatic cases over the last 14 days, which highlighted that risks of a resurgence and even spread of the epidemic still existed, Mi noted.

"We need to keep highly vigilant and make epidemic prevention and control a part of our regular work agenda while advancing efforts to resume production and daily life," Mi added.
