Spatial and temporal scanning analysis of infectious disease of C category in changde from 2010 to 2015 / 中国医师杂志

ABSTRACT

Objective To explore the temporal and spatial distribution characteristics of C infectious diseases in Changde City from 2010 to 2015,grasp the situation of high priority areas so as to provide theoretical basis for prevention and control.Methods Spatio-temporal scanning was performed by using SaTScan software,and the spatial and temporal clustering regions of C infectious diseases were presented by ArcGIS software.Results The prevalence of C infectious diseases in Changde City was higher than that in other times in 2010 (RR =4.16,P =0.000).(LLY =497.019,RR =1.48,P ＜ 0.001).There was a most likely clustering area in the Wuling area of Changde,and the incidence of C infectious diseases in this area was higher than that in other areas,and the difference was statistically significant.Simple spatial scanning analysis and space-time scan analysis were also found in South Central Deshan Development Zone (LLR =277.131,RR =1.77,P ＜0.001) and Northern Linli county (LLR =136.683,RR =1.27,P ＜ 0.001) are two secondary gathering area,where the actual number of cases were much more than the theoretical number of cases,the difference was statistically significant.In addition,there are other regions of the existence of sub-aggregation state.Conclusions Spatio-temporal scanning analysis method can be applied to the high incidence of infectious diseases in Changde City.Combined with geographic information system that we can show the incidence of disease and disease in a more intuitive and comprehensive way,which can provide a scientific reference for the future prevention and control of the disease.
