Abstract:
Objective To explore and analyze the spatial distribution characteristics of hand - foot - mouth disease in Hangzhou city. Methods Based on the incidence of hand - foot - mouth disease, the whole and local spatial autocorrelation analysis was used to test the spatial heterogeneity by the software GeoDa095i. Results A total of 5534 cases of hand-foot-mouth disease were reported in Hangzhou city in 2011 with the reported incidence of 63. 61/100000. The wholel Moran’s I index was 0. 33(P<0. 05)indicating that the disease had high spatial cluster occurrence. Local spatial autocorrelation analysis showed that several districts including Gongshu,Jianggan,Xihu and Xiaoshan had high cluster occurrence(LISA=0. 4135,0. 4600,0. 1785 and 0. 3508 respectively,all P<0. 05)while Chun′an county and Tonglu county had the low cluster occurrence(LISA=0. 6923 and 0. 6762 respectively,both P<0. 05). Conclusion The spatial distribution of hand - foot - mouth disease in Hangzhou city is not random distribution and has aggregation phenomenon.
