A way to track governments’ response and people’s mobility changes in response to COVID-19 pandemic

摘要

Social-control measures, medications and a vaccine are key weapons against the pandemic [1]. Be- fore specific medications and vaccines are proven to be effective and can be used worldwide, phys- ical distancing measures are still highly relevant in the fight against COVID-19 [2,3]. Governments around the globe have been taking a wide range of physical distancing measures in response to the CO- VID-19 outbreak, such as school closure, workplace closure, cancellations of mass gatherings and stay at home orders. However, it’s hard to compare the measures implemented in different countries directly. First, a same measure might be implemented in different countries with different degree and intensity. Also, citizens’ acceptability of the measure differs across countries.
