Using a dataset including 65 Chinese cities, Yao et al. [1] found no significant association between COVID-19 transmissibility and temperature or ultraviolet (UV) radiation. Using a dataset including 154 Chinese cities, Ran et al. [2] reran the analyses and found a nonlinear negative association between temperature and COVID-19 transmissibility.There is a robust and significant negative association between #COVID19 transmissibility and ambient temperature at the country level. An increase of 1°C in temperature is associated with a decrease in the prevalence of COVID-19 by ∼5.4%. https://bit.ly/32OTBiS ER -
