The ensuing results show that meteorological factors play a key role in regression models of COVID-19 risk, with ultraviolet radiation (UV) as the main driver. These results are corroborated by statistical correlation analyses and fixed-effect regression modeling where UV radiation coefficients are found to be significantly negatively correlated with COVID-19 transmission rates.
