Rotaviruses were detected by counterimmunoelectro-osmophoresis in the feces of 16 (13.8%) of 116 infants and young children with gastroenteritis during a 5-month period (September 1979 through January 1980) in Ife, Nigeria. The rate of rotavirus detection varied inversely with relative humidity and was highest in December (38.5% positive) when the humidity was lower. There was not such a distinct relationship with temperature or vapor pressure; and although the rate of rotavirus detection was higher in the drier months (November to January; 19.3% positive) than in the rainy season months (September and October; 8.5% positive), the average humidity was lower in the drier months than in the rainy months. Low relative humidity (49 to 78%) is apparently the most important environmental factor for rotavirus survival and spread in this area.
1979年9月至1980年1月的5个月期间，在尼日利亚伊费，采用对流免疫电渗法在116例患肠胃炎的婴幼儿粪便中检测到16例（13.8%）轮状病毒。轮状病毒的检出率与相对湿度呈负相关，在湿度较低的12月检出率最高（阳性率为38.5%）。与温度或蒸汽压没有如此明显的关系；虽然轮状病毒的检出率在较干燥的月份（11月至1月；阳性率为19.3%）高于雨季月份（9月和10月；阳性率为8.5%），但较干燥月份的平均湿度低于雨季月份。低相对湿度（49%至78%）显然是该地区轮状病毒存活和传播的最重要环境因素。
