目的探索河北省卢龙县轮状病毒腹泻与气象因素之间的关系。方法监测2000-01/2003-06河北省卢龙县每月5岁以下轮状病毒腹泻住院患者数以及当地每月的温度、湿度和降雨量。计算卢龙县轮状病毒腹泻的月住院率,并对轮状病毒腹泻和温度、湿度及降雨量进行相关和回归分析。结果RV腹泻与温度之间的相关系数为-0.75,与湿度及降雨量无相关性。RV腹泻发病和温度之间呈现指数曲线的关系,指数曲线方程:y=13.2-2.2x+0.11x2-0.0016x3。结论卢龙县婴幼儿轮状病毒腹泻主要受温度的影响,与温度呈负相关,不受湿度和降雨量的影响。
Objective To explore the relationship between rotavirus diarrhea and meteorological factors in Lulong County of Hebei Province. Methods The number of hospitalized patients with rotavirus diarrhea under 5 years of age and monthly local temperature, humidity and rainfall in Lulong County, Hebei Province from January 2000 to June 2003 were monitored. Calculate the monthly hospitalization rate of rotavirus diarrhea in Lulong County, and carry out correlation and regression analysis on rotavirus diarrhea, temperature, humidity and rainfall. Results The correlation coefficient between RV diarrhea and temperature was -0.75, with no correlation with humidity and rainfall. RV diarrhea incidence and temperature showed an exponential curve relationship between the exponential curve equation: y = 13.2-2.2x + 0.11x2-0.0016x3. Conclusion The infant rotavirus diarrhea in Lulong County is mainly affected by temperature, which is negatively correlated with temperature and is not affected by humidity and rainfall.
