China classifies all counties as low-risk for the novel coronavirus disease (COVID-19) from Thursday, Mi Feng, spokesperson for the National Health Commission (NHC), said at a media briefing. 

The move came as no domestic cases have been reported in the Chinese mainland for four consecutive days as of Wednesday, with no new deaths for 22 consecutive days.

Mi also warned of "a lot of uncertainties" of the epidemic situation and called for continuous efforts in patient treatment and rehabilitation management and implementation of regular epidemic prevention and control measures, to guard against the rebound of the epidemic. 

According to the latest NHC report, there're 295 active domestic cases on the Chinese mainland as of Wednesday, including 23 patients who are in critical conditions.

There are also 246 active imported cases on the Chinese mainland, said the report.
