Recent studies have shown that the mortality of the new coronavirus pneumonia is positively correlated with the temperature difference between day and night and negatively correlated with the relative humidity.
The study was completed by a team of professor Luo Bin from the School of Public Health of Lanzhou University and was published on medRxiv, a preprinted platform for medical papers on March 18.
This study aimed to analyze the association between mortality rates of new coronavirus pneumonia and weather parameters.

According to data released by the Hubei Provincial Health and Health Commission, 2299 deaths from new coronavirus pneumonia in Wuhan from January 20 to February 29, 2020, with an average of about 56 deaths per day.
Researchers collected data on the daily deaths, meteorological and air pollutants of new coronavirus pneumonia in Wuhan during this period. Mathematical models were used to study the effects of temperature, humidity, and day and night temperature differences on the daily mortality of new coronavirus pneumonia.
During this period, the minimum temperature in Wuhan was 1.8 degrees Celsius, the maximum temperature was 18.7 degrees Celsius, and the day and night temperature difference (DTR) ranged from 2 to 17.5 degrees Celsius. Relative air humidity is 59% to 97%, with an average of 83%.
The analysis found that the mortality of the new coronavirus pneumonia was significantly related to changes in temperature and humidity, which was positively related to the temperature difference between day and night and negatively related to the relative humidity.
For each additional unit of diurnal temperature difference (DTR), the mortality rate of new coronavirus pneumonia increases by 2.92%, and the increase in temperature and absolute humidity is related to the decline in mortality.
