We studied the relationship between the incidence of coronavirus disease 2019 (COVID-19), demographical, and climatological measurements in different regions across the world. Lower solar irradiance and higher population density were independent predictors of greater COVID-19 outbreaks. Further studies on the potential protective effect of sunlight over COVID-19 are warranted.
