Objective:To explore the impact of meteorological factors on the outbreak of bacillary dysentery, so as to provide suggestions for disease prevention.Methods:Based on the Chinese medicine theory of Yunqi, the descriptive statistics,single-factor correlation analysis and back-propagation artificial neural net-work were conducted using data on five basic meteorological factors and data on incidence of bacillary dysentery in Beijing, China,for the period 1970-2004.Results:The incidence of bacillary dysentery showed significant positive correlation relationship with the precipitation,relative humidity,vapor pressure,and temperature,respectively. The incidence of bacillary dysentery showed a negatively correlated relationship with the wind speed and the change trend of average wind speed.The results of medical-meteorological forecast model showed a relatively high accuracy rate.Conclusions:There is a close relationship between the meteorological factors and the incidence of bacillary dysentery,but the contributions of which to the onset of bacillary dysentery are different to each other.
