How did a critical COVID-19 patient recover from lung transplant?

Cui Zhiqiang, a critically ill COVID-19 patient who received a double-lung transplant after his lungs were irreversibly fiberized, was discharged from the People's Hospital of Wuhan University two weeks ago and then transferred to a local rehabilitation center. Ten COVID-19 patients worldwide have undergone such lung surgeries, and Cui was the first to be discharged from hospital.
