The impact of meteorological and environmental conditions on the spread of COVID-19 / 公共卫生与预防医学

ABSTRACT

Objective To understand the impact of meteorological and environmental conditions on the spread of COVID-19, and to provide a scientific basis for prediction, prevention and control of COVID-19. Methods The number of confirmed cases, population density and meteorological data of all cities in Hubei Province during COVID-19 outbreak period were collected. The relationship between COVID-19 infection rate and climatic factors were analyzed using Excel and SPSS software. Results The infection rate of COVID-19 had the greatest correlation with population density. The infection rate of COVID-19 showed a very significant power-law relationship with the number of the hot days before COVID-19 outbreak, and it also had a good correlation with the high temperature accumulation, the rank of hot days and the drought intensity. Conclusion The adverse effect of high temperature and heat wave on the human body had an impact on the spread of COVID-19. The ability of people in different areas to resist high temperature was different because of different climates. Drought may affect the spread of COVID-19 by destroying the ecological environment.
