Patients in Wuhan suffered the biggest lose of lifes. Outside of Wuhan, patients were better off in hot/sunny provinces (0.75%， 12/1605), like Guangdong, Guangxi, Fujian, Yunan, (also Jiangxi 0.125%, 1/831), then cold provinces (2.5%， 49/2110), like Henan, Heilongjiang, Beijing, Hebei. Those hot provinces have temperature of 20-25C, WHEREAS cold provinces were only near 0-5 C or below. WUHAN is between hot and cold provinces.

From these China web data, it is likely the death rate for COVID-19 will be below 1% in the summer if it could stay during summer at all.

The only death of US COVID-19 patients was in a cold state Washington State.
