据报道,轮状病毒胃肠炎常发生在冬季,而夏季则很少见。本文研究轮状病毒胃肠炎住院患儿与发病前的上个月份气候变化的关系,作者于1974年1月至1979年5月和1980年初,在华盛顿的一所医院对罹患急性胃肠炎的住院婴幼儿(3月龄～≥25月龄)进行了研究。使用电镜和酶联免疫吸附试验方法检测患儿粪液,确诊为轮状病毒感染,并比较在不同年份的相同月份里气温、降雨量以及降雨天数与该病的发病情况。在相同的月份里,气候寒冷而干燥的月平均温度6.1℃时,轮状病毒胃肠炎的发病率为54%(178/331),而温暖且潮湿的月平均温度9.6℃时,发病率为40%(97/244),前者比后者发病率高并呈显著性差异(P<0.001)。月平均降雨量为4.6cm时,发病率为51%(162/316),比月平均降雨量为10.9cm
It is reported that rotavirus gastroenteritis often occurs in winter, while in summer it is rare. This article studies the relationship between hospitalized children with rotavirus gastroenteritis and the previous month’s onset of climate change. From January 1974 to May 1979 and early 1980, a study was conducted at a hospital in Washington for acute gastroenteritis Of hospitalized infants (3 months to 25 months of age) were studied. Electron microscopy and enzyme-linked immunosorbent assay were used to detect fecal fluid in children and diagnosed as rotavirus infection. The temperature, rainfall and rainfall days in the same months of different years were compared with the incidence of the disease. In the same months, the incidence of rotavirus gastroenteritis was 54% (178/331) when the monthly average temperature of cold and dry climate was 6.1 ℃, while the incidence of rotavirus gastroenteritis was 9.6 ℃ when the average monthly temperature was 9.6 ℃ 40% (97/244). The former had a higher incidence and significant difference than the latter (P <0.001). The average monthly rainfall of 4.6cm, the incidence rate was 51% (162/316), than the average monthly rainfall of 10.9cm
