Xiaotangshan Hospital, which was previously used to quarantine SARS patients in Beijing, cleared all COVID-19 cases on April 28 and is scheduled to cease operation April 29. 

The hospital, located in the city's northern suburb, was renovated and put into operation on March 16 for the screening and treatment of imported mild and common confirmed COVID-19 cases, suspected cases and those who need to be tested.

In the treatment and control of SARS, or Severe Acute Respiratory Syndrome, which spread rapidly on the Chinese mainland in 2003, Beijing built Xiaotangshan Hospital, a temporary medical center, in just a week.
