Prevalence and genetic characteristics of norovirus epidemics in Guangdong province, 2021

  • 摘要:   目的  分析2021年广东省诺如病毒聚集性或暴发疫情的流行病学特征。  方法  收集广东省2021年1 — 12月诺如病毒感染疫情样本及相关基本信息,通过实时荧光定量PCR(qRT-PCR)对样本进行诺如病毒的鉴定,筛选诺如病毒GI型和GII型阳性样本,通过PCR扩增、建库、测序、序列拼接后对其进行基因分型。  结果  2021年广东省共报告141起诺如病毒感染疫情,其中92.91 %(131起)的疫情发生在托幼机构或学校;疫情的流行季节为冬春季。73起疫情(51.77 %)确定了基因分型。94.52 %(133起)的诺如病毒感染疫情由GII型引起,其中GII.2[P16]和GII.4[P31]分别占比39.13 % 和23.19 %。  结论  广东省2021年诺如病毒疫情主要发生在托幼机构和学校,GII.2[P16]和GII.4[P31]分别是春季和冬季的主要流行型别,仍需继续加强诺如病毒疫情监测以及分子分型研究。
