目的探讨越秀区手足口病发例数与气象因素和空气污染指数的关系,为手足口病预防控制提供科学依据。方法对越秀区2010~2011年手足口病疫情与气象因素和空气污染指数资料进行相关分析。结果 2010~2011年越秀区手足口病发例数与当月的降雨量、平均温度呈中度正相关关系(r=0.678、0.566,P<0.01),与湿度呈中度正相关关系(r=0.441,P<0.05),与污染物PM10呈负相关关系(r=-0.445,P<0.05),与日照时间的相关无统计学意义(r=0.191,P>0.05);与污染物NO2和SO2的相关无统计学意义(r=-0.289、-0.366,P>0.05)。结论越秀区手足口病月发病数与当月的降雨量、平均温度、湿度、污染物PM10有关。
Objective To investigate the relationship between the number of hand-foot-mouth disease and the meteorological factors and air pollution index in Yuexiu district, and to provide a scientific basis for the prevention and control of hand-foot-mouth disease. Methods The correlation analysis of epidemic situation, meteorological factors and air pollution index data of hand-foot-mouth disease in Yuexiu District from 2010 to 2011 was conducted. Results The incidence of hand-foot-mouth disease in Yuexiu district from 2010 to 2011 showed a moderate positive correlation with the monthly rainfall and average temperature (r = 0.678, 0.566, P <0.01) and a moderate positive correlation with humidity (r = (R = -0.445, P <0.05), and there was no significant correlation with sunshine time (r = 0.191, P> 0.05) SO2 was not related to statistical significance (r = -0.289, -0.366, P> 0.05). Conclusion The incidence of HFMD in Yuexiu District was related to the monthly rainfall, average temperature, humidity and pollutant PM10.
