IJING, Aug. 4 (Xinhua) -- The Chinese capital Beijing has decided to cancel large-scale exhibitions and events scheduled this month, after three locally-transmitted COVID-19 cases were newly confirmed in the first 12 hours of Wednesday.

The municipal government has urged relevant departments to carry out timely epidemiological investigations on specific close-contact groups with large mobility, including taxi and ride-hailing drivers, and delivery men.

Beijing plans to step up the screening of people entering the city from areas with reported COVID-19 cases. It also urges relevant departments to take better care of medical workers at the frontline of disease prevention and control.
