Half of Shanghai's major makeshift hospitals have been shut thanks to the sharp decrease in the number of COVID-19 patient admittances.

Five of the 10 city-level makeshift hospitals, mainly in the suburban districts, have been suspended as of Friday, said Ding Bo, a city official in charge of the transportation of COVID-19 patients.

At present, there are 50,000 patients under medical observation or treatment at the makeshift hospitals, only 20 percent of the peak number, Ding said.
