Previous studies have investigated the epidemiology of different intestinal infectious diseases. First, temporal analysis of different intestinal infectious diseases was conducted. The initial efforts in conducting a temporal analysis investigated the temporal variations in the incidence rates of different diseases in different age groups and areas. For example, Tian et al. analysed the temporal characteristics of HFMD and the relationship between meteorological factors and the incidence of HFMD in Beijing, China. May to July is the period with peak HFMD incidence each year in Beijing [8] . Xiao (1, 1) ] to predict the trend in the incidence of typhoid using data collected from Wuhan City in China from 2004 to 2015 [10] . Liu et al. forecasted the incidence of bacillary dysentery diseases by applying the seasonal trend model based on the moving average method, which forecast the incidence of Hepatitis A in 2015 [11] . Ming et al. investigated the seasonal signals and long-term trends in a series of 10 IGS sites in China [12] . Xing et al. conducted a study examining the epidemiological characteristics in China from 2008 to 2012, emphasizing seasonal patterns among people at different ages [13] . Temporal analyses of infectious diseases have allowed researchers to develop a wide range of research methods, namely, time series analysis and seasonal analysis. However, temporal analysis failed to reflect the overall circumstances of infectious intestinal diseases.
