【摘要】：目的探讨成都地区腹泻婴幼儿轮状病毒检出率与气象因素的关系,为预测轮状病毒的流行和预防控制提供依据。方法收集2011.8-2013.6成都地区婴幼儿腹泻粪便样品共465份,采用RT-PCR检测轮状病毒,并收集同期成都市月度气象资料(气温、相对湿度、降雨量)。使用SPSS21.0对各季节检出率进行卡方检验,对轮状病毒检出率与各气象因素进行Pearson相关分析和多重线性回归分析,建立回归模型。结果冬季轮状病毒检出率高于夏秋两季,夏季检出率为四季最低,而温度为影响检出率的主要因素,温度每上升1℃,检出率下降1.402个百分比。结论成都地区轮状病毒感染主要发生在冬春两季,温度与检出率呈负相关,是影响当地轮状病毒感染的主要气象因素。
[Abstract]:Objective to investigate the relationship between the detection rate of rotavirus and meteorological factors in infants with diarrhea in Chengdu, and to provide the basis for predicting the prevalence of rotavirus and preventing and controlling rotavirus. Methods 465 fecal samples of infantile diarrhea were collected from 2011 to 2013.6 in Chengdu. RT-PCR was used to detect rotavirus, and monthly meteorological data (temperature, relative humidity, rainfall) were collected in Chengdu during the same period. The detection rate of rotavirus in each season was detected by SPSS21.0 by chi-square test. The detection rate of rotavirus in winter was higher than that in summer and autumn, and the detection rate in summer was the lowest in four seasons. However, temperature was the main factor affecting the detection rate, and the detection rate decreased by 1.402% for each temperature rise of 1 鈩，
