  • 摘要:   目的  了解浙江省学校诺如病毒感染暴发疫情的流行特征,提出当前防控特点。  方法  收集2019年1月1日至12月31日浙江省学校发生的诺如病毒胃肠炎暴发疫情资料,采用描述性流行病学方法。  结果  2019年报告173起学校诺如疫情,涉及170所学校,累计3172例病例,波及161711人,总罹患率为1.96%。 诺如病毒疫情主要发生在小学(53.18%)和托幼机构(27.16%),病例的年龄集中在7~12岁(47.95%)。 疫情在春季和秋冬季均有发生,传播途径主要为人传人(94.80%),食源性传播和水源性传播引起的疫情较少。 临床症状以腹泻、呕吐为主,基因型以GⅡ型为主(121起,69.94%)。  结论  浙江省学校诺如病毒胃肠炎暴发疫情主要发生在小学和幼儿园,传播途径多为人传人,学校应重视病例的排泄物/呕吐物及环境消毒处理。
