Those numbers are totally eschewed
from the Chinese medical,papers at least 20 to 25% of the patients in China required intensive care (ventilator, oxygen, iv, antibiotics) and that is in a country that has built hospitals in 10 days and military and civilian medical personnel that have not refused to participate and die in the course of stopping the spread
now in countries outside China even in USA there are not enough ventilators, oxygen masks, Icu beds and i can assure you that medical personnel are going to flee from getting exposed to the virus, just imagine that, maybe is time to buy an oxygen bottle, masks and survival rations and get away from major urban areas. I asked a couple of my colleagues here (I am a retired md) who are active practicing and the answer was in the negative, not willing to take the risks for the benefits (ie risks) implied.
