Analysis of spatio-temporal transmission characteristicsfor H7N9 infection in China

To reveal the temporal and spatial development and evolution of human H7N9 infection in China, based on the statistical data of human H7N9 infection from 2013 to 2017, time series and standard deviation ellipse analysis were performed. Firstly, the epidemic time series was analyzed with month as tim...

On this basis, the whole epidemic period was divided into stages, and the epidemic change law of each stage was analyzed. Then the standard deviation ellipse is established according to the location of the epidemic cases, and the spread of the epidemic situation is described by the changes of the ellipse center, azimuth and area in each stage. Finally, through the time and space analysis of the three typical areas, the spread law of the epidemic was further verified. The results show that, the high incidence period is from December to May every year, especially in January and February. The proportion of cases in these two months is as high as 51.74%.
