Table 2.

The effect of a one-unit increase in average temperature, relative humility, AQI, MSI and UTI on daily death cases of COVID-19

Factors Relative Risk 95% CI p value
Temperature (°C) 0.948 [0.931,0.966] < 0.001
Relative humility (%) 0.994 [0.987,1.000] 0.054
AQI 0.999 [0.996,1.002] 0.534
MSI 0.642 [0.362,1.137] 0.120
UTI 1.959 [1.009,3.804] 0.042

Note: AQI air quality index, MSI migration scale index, UTI urban travel index, CI confidence interval

The temperature delayed period of the final model was set to 15 days
