The dynamics of Covid-19: weather, demographics and infection timeline

Category: Article Summary

Topic: Transmission

• Pedrosa studied the effects of weather variables, population density and the timeline of Covid-19 infection on the early pace of spread of Covid-19 all 50 U.S. states and 110 countries.  Findings suggest that higher the temperature and the absolute humidity were associated with faster Covid-19 transmission in U.S. states in the early stages of the outbreak. 
• A strong positive association was also observed between population density and early faster spread of Covid-19. When these variables are considered together, only population density and the timeline variable show statistical significance. Basic models for other countries also showed weather variables lose statistical significance when timeline is controlled for.
