一起G.4 [P16] 型诺如病毒感染暴发疫情调查

Investigation of an outbreak of norovirus G.4P16 infection

  • 摘要:
      目的   分析2021年山东省某小区一起诺如病毒感染暴发疫情流行因素,为制定有效的防控措施提供科学依据。
      方法   采用现场流行病学方法调查、分析疾病的流行情况,采集水样本、典型病例的粪便或呕吐物、密切接触者的肛拭子标本进行胃肠炎病毒检测,对阳性样本进行基因分型。
      结果   搜索到病例69例(9例为小区内幼儿园儿童,60例为社区居民), 临床表现主要为呕吐(76.81%),腹泻(69.57%)。 0~5岁儿童罹患率最高(21.18%)。 17份病例标本和2份密切接触者标本GⅡ组诺如病毒阳性,基因型均为GⅡ.4[P16]。
      结论   本次事件是由GⅡ.4[P16]型诺如病毒引起的暴发疫情,是由患病儿童呕吐物造成环境污染,社区人员密切接触导致,及时识别和妥善处置是疫情防控的关键。

     

    Abstract:
      Objective   To analyze the epidemiological characteristics of an outbreak of norovirus GⅡ.4P16 infection in Shandong province in 2021, and provide evidence for the effective prevention and control of the outbreak.
      Methods   A field epidemiologic surveys were carried out. Water, stool and vomitus samples from the infection cases and anal swabs from some of close contacts were collected for pathogen testing and genotyping.
      Results   From 4 to 16 march, a total of 69 infection cases were found in the community. The main clinical manifestations included vomiting (76.81%) and diarrhea (69.57%). The attack rate was highest in children aged 0–5 years (20%). Clinical samples from 17 cases and two close contacts were tested norovirus GⅡpositive. GⅡ.4 P16 was the only genotype.
      Conclusion   The outbreak was caused by norovirus GⅡ.4P16 due to environment contamination by the vomitus of sick children and close contacts by the residents. The outbreak was controlled by taking timely detection and appropriate response measures.
