Beijing authorities on Wednesday established a leading group for the prevention and control of coronavirus pneumonia outbreaks.

Seven separate groups were set up under the leading group in the capital according to Beijing Daily, to launch a joint prevention and control mechanism.

Daily meetings will be convened to probe the current situation of the epidemic and make plans for the future.

Supervision and inspection checks have been conducted in medical institutions in Beijing, including designated hospitals and comprehensive training for medical staff.
