Infectiousness of places - Impact of multiscale human activity places in the transmission of COVID-19.

ABSTRACT: COVID-19 raises attention to epidemic transmission in various places. This study analyzes the transmission risks associated with human activity places at multiple scales, including different types of settlements and eleven types of specific establishments (restaurants, bars, etc.), using COVID-19 data in 906 urban areas across four continents. Through a difference-in-difference approach, we identify the causal effects of activities at various places on epidemic transmission.

At the macro-scale, contradicting common beliefs, it is consistent across countries that transmission does not increase wi
