These findings persisted irrespective of whether Italy was included in our analysis or not, whether we used country dichotomization by climate criteria or included all countries irrespective of climate classification. Intra-State analysis of American (USA) data did not identify a significant correlation Our results were devised by developing an online surveillance tool (available at All rights reserved.

Snippet: In this study we analyzed the spread rate of the novel COVID-19 pandemic in relation to climate variables. We identified a significant moderate negative correlation between the rate of COVID-19 RR and RoS and increasing temperature and dew point. Furthermore, by dichotomizing countries into "warm" and "cold" climate (based on predefined average March temperature >15 degrees Celsius and latitude) categories we identified a significantly lower RR.....
