ABSTRACT
ABSTRACT:In order to explore the spatial clustering and influential factors of HFMD in Chongqing ,China from 2008 to 2012 ,spatial autocorrelation and spatial regression analysis (using the spatial lag model in this study ) were carried out using the HFMD data of 38 districts (counties) from 2008-2012 in Chongqing by OpenGeoDa ,and the HFMD case‐based data was collected from the Disease Supervision Information Management System of Chongqing Center for Disease Control and Preven‐tion .We found that the global Moran’s I coefficient of Chongqing from 2009 to 2012 was 0 .458 7 ,0 .567 5 ,0 .398 6 ,and 0 .606 0(P0 .05) .Results of multi‐factor spatial lag regression analysis demonstra‐ted that the incidence of HFMD was positively related with urban rate (β=1 .667 6 , P=0 .001 6) ,and negatively correlated with medical technical personnel per thousand (β= -0 .000 2 ,P=0 .019 8) .In general ,the incidence of HFMD was found ge‐ographically clustered in Chongqing from 2009 to 2012 which was significantly influenced by urban rate and medical technical personnel per thousand population ,and while the urban rate was the main factor .
