Understanding and addressing public health disparities through the lens of human mobility data

Abstract

Temporal snapshots of the pandemic in the U.S. Red circles represent the infected counties, and the grey circles are the uninfected counties. e-h: Correlations between 7-days moving average of the single-source effective distance from the initial source (Suffolk, MA) and arrival times accordingly for counties that already have more than two confirmed cases in the date of a-d. i-l: Shortest-path trees for counties in a-d. . . . . . . . . . 2.3 Multiple-source effective distance outperforms single-source effective distance in predicting arrival times in the U.S. when multiple sources co-exist. a: Swarm plot of RMSE for various combinations of sources and transition days. The solid curve shows the combination with minimum RMSE on a given transition day. b-e: Correlation between 7-day moving average multiple-source effective distance and the integral of mobility rate when Santa Clara, CA and Suffolk, MA are the threatening sources. The dates in this row represent the transition day when the second source starts to function.
