Professor Zhang Wenhong said that the experience of China and COVID-19 fighting for more than two months is helpful to the United States. After about 80% of people suffer from COVID-19, they can survive it by themselves; about 20% need oxygen therapy and must go to the hospital. Therefore, in most cases, American hospitals will not accept patients. From the American medical system and the prediction of the epidemic, they know very well what their limits are. They know what’s going on, and the beds won’t hold the cases they should receive.
