[Spatial temporal distribution of mumps in Gansu, 2009-2013].

Objective To detect the spatial temporal distribution of mumps in Gansu by means of spatial statistics. Methods The county-based incidence of mumps from 2009 to 2013 was used to calculate the global Moran’s I and local G statistics, and analyze its spatial temporal distribution characteristics. Results The incidence of mumps in Gansu were spatial auto-correlated from 2009 to 2013 respectively (P<0.001), and the hot spots were mainly distributed in Hexi area, while the cold spots were distributed in Tianshui, Longnan and Qingyang. Spatial temporal analysis showed that the high incidence of mumps was most likely to be detect in Hexi area (RR=3.05, LLR=4 670.995, P<0.001), and the low incidence was most likely to be detect in Longdong area (RR=0.36, LLR=1 980.686, P<0.001). Conclusion The spatial and spatial temporal clustering of mumps existed in Gansu from 2009 to 2013, the results can be used in the development of mumps prevention and control measure in Gansu.
