夏末秋初,气温开始下降,轮状病毒迅速滋生。由于婴幼儿的免疫系统不能很快地适应夏秋之交的天气变化,因而更容易受到病毒的侵害,发生腹泻。有数据显示,85%的秋季腹泻患者为10岁以下的少年儿童,而6个月大到3岁的营养不良、佝偻病、贫血患儿和体弱多病的婴幼儿更容易受到侵害。 In late summer and early autumn, the temperature began to drop, and rotavirus rapidly breeds. Because infants and young children’s immune system can not quickly adapt to changes in the weather at the turn of the summer, it is more susceptible to viruses and diarrhea. Data show that 85% of fall diarrhea patients are children under 10 years of age, and 6 months to 3 years old malnutrition, rickets, anemia and infirm infants and young children are more vulnerable.
