Abstract:
We used the Brucella data in Xinjiang between year 2009 to 2010 to explore and analyze the spatial clustering fea‐tures of brucellosis in Xinjiang ,and provided the basis for prevention and control on brucellosis in Xinjiang ,China .The time and population distribution of brucellosis in Xinjiang was analyzed for statistical analysis with descriptive epidemiology .Mean‐while ,we also used quartile classification methods to map the incidence of brucellosis in Xinjiang spatial distribution ,and calcu‐lated the Global Moran’s I index on the spatial clustering analysis .Results showed that brucellosis in Xinjiang had obvious sea‐sonal differences (peaked in May‐September) ,more cases for male than that for female (gender ratio‐‐2 .96∶1) ,and the total incidence of 74% were farmer and herdsman ,mainly concentrated at th e age of 40 to 60 years old .Compared with the onset range of brucellosis in 2009 ,there were clear tendency to spread in 2010 .The Global Moran’s I index was 0 .116 4 (P=0 .017) ,showing the spatial clustering on the incidence of brucellosis in Xinjiang .The incidence of hot spots concentrated in Tacheng and Altay ,and the incidence of cold spots concentrated in Kashi .The incidence level brucellosis has significant spatial aggregation in the area of Xinjiang ,which should be strengthened the prevention and control of high‐risk areas .
