China classified all of its counties as low-risk for the novel coronavirus disease (COVID-19) on May 7, said Mi Feng, a spokesperson for the National Health Commission, at a press conference in Beijing. Primary and high school students across China have also been making a welcome return to classes after a long vacation caused by the COVID-19 epidemic.

However, there are still uncertainties regarding the epidemic, said Mi, calling for continuous efforts in patient treatment and epidemic control measures to prevent an infection rebound.
