BEIJING — Most enterprises in China have effectively implemented measures on epidemic prevention and control, health authorities have found in a recent special campaign.

Most companies have stepped up monitoring employees' health conditions, guided employees to better protect themselves and developed COVID-19 emergency response capabilities, said Xie Yang, an official with the National Health Commission, at a press conference in Beijing on May 17. 

No enterprises have caused any rebound or spread of the epidemic as they resume work and production, Xie said.

The campaign targeted enterprises with employees working in densely populated venues in regions categorized as having high or middle risks for the spread of COVID-19, according to Xie.
