摘要：
The rising number of people infected by Hand-Foot-Mouth Disease (HFMD) in China poses a great threat to public health and a critical challenge to disease prevention and control in recent years. This paper used regional monthly statistics of HFMD in 2017 when HFMD was common in China. The GeoDetector, spatial autocorrelation, and other analysis methods were adopted to analyze the influence of meteorological factors (i.e., temperature, precipitation) on the prevalence of HFMD and its spatial and temporal differentiation. The results show that: (1) Temporally, the prevalence of HFMD had significant seasonal differences in major cities of China in 2017, with a single prevalence peak or double prevalence peaks (i.e., high-low peak, double high peak). Moreover, the prevalence of HFMD in those cities had a significant spatial correlation in February, April, and December; (2) Spatially, the HFMD in China was characterized by high prevalence level in southeast provinces or cities and low prevalence level in northwest provinces or cities, showing a decreasing trend from southeast to northwest along precipitation gradient; (3) According to the spatial and temporal distribution of HFMD outbreak period (from April to August) at provincial and city level in 2017, HFMD spread from southeast to northwest, and then retreated from west to east; (4) The prevalence of HFMD in major cities in China was correlated with the average annual precipitation and average annual temperature, which were fitted by a quadratic function (R2=0.6623) and an exponential function (R2=0.6469), respectively; and (5) The interaction effect between temperature and precipitation on HFMD resulted in a double-factor nonlinear enhancement and was more significant than a single factor during the spread of HFMD. The prevalence of HFMD in China is influenced by meteorological factors and is significantly different at spatial and temporal scales. Our results can provide reference for the prevention and control of HFMD at national level. © 2021, Science Press. All right reserved.
