cord-283891-m36un1y2	Hu, Bisong	First, second and potential third generation spreads of the COVID-19 epidemic in mainland China: an early exploratory study incorporating location-based service data of mobile devices	2020-05-17		.txt	text/plain	4656	220	47	Methods We used spatiotemporal data of COVID-19 cases in mainland China and two categories of location-based service (LBS) data of mobile devices from the primary and secondary epidemic sources to calculate Pearson correlation coefficient,r, and spatial stratified heterogeneity, q, statistics. Here, using location-based service (LBS) data of mobile devices, we analyzed the spatiotemporal association of the confirmed COVID-19 cases and human movements from the sources of the epidemic outbreak, and revealed the first, second and potential third generation spreads of the COVID-19 epidemic in mainland China. Based on the above datasets of COVID-19 cases in mainland China and two categories of location-based service data of mobile devices from the epidemic sources, we calculated their Pearson correlation coefficient, r, and spatial stratified heterogeneity (SSH), q, statistics.	./cache/cord-283891-m36un1y2.txt	./txt/cord-283891-m36un1y2.txt
