Herein, we use a global velocity model to examine the effectiveness of containment measures on the rate of COVID-19 spread at spatial scales. Velocity models were parameterised to locate COVID-19 analogues within a minimum exposure distance. We found that COVID-19 spread 193 analogue locations at 3.03km per day (range: .5 - 7.81km per day). We applied conventional time-series methods to study the effectiveness of shelter-in-place virus containment strategy as represented by device exposure and state-wise emergency declaration metrics, on velocity of virus spread. The best model comprised of high device exposure and state-wise emergency rank, explaining 44% of the variation in velocity of COVID-19. Our findings elucidate the importance of governments' response time and individual-level compliance in managing pathogens during epidemics.
