我国诺如病毒感染性腹泻流行现状及防制措施建议

Infectious diarrhea epidemics caused by norovirus and its control strategy in China

  • 摘要: 目的 为加强我国诺如病毒感染性腹泻监测与防控工作,更新相关技术指南,提出技术关键点的措施建议。 方法 收集2006-2013年在全国突发公共卫生事件报告系统所报告的其他感染性腹泻暴发数据、全国病毒性腹泻监测网络2006-2012年数据以及国内外诺如病毒感染监测和控制技术指南及有关文献,分析我国诺如病毒发病情况、病原分型和暴发危险因素,监测及防控工作中存在的问题,比较国内外相关防控技术指南。 结果 2006-2013年全国诺如病毒腹泻暴发疫情报告数逐年上升,共报告56起,发病4979例,平均每起暴发89例病例,主要病原类型包括GⅠ型、GⅡ型。在病毒性腹泻监测哨点医院住院的5岁以下儿童腹泻病例中,诺如病毒检出率从2007年的11.2%上升至2011年20.3%,2012年为15.3%。 结论 我国诺如病毒感染性腹泻暴发和住院病例呈上升趋势,暴发规模较大,暴发监测的敏感性有待改进。本研究提出诺如病毒感染性腹泻防控主要技术措施建议,对指导开展我国诺如病毒腹泻防控工作,更新技术指南有重要参考价值。

     

    Abstract: Objective To provide evidence for the updating of nororvirus infection prevention and control guideline and strengthen norovirus infection surveillance and outbreak control in China. Methods Outbreak data of other infectious diarrhea reported during 2006-2013 and incidence data of viral diarrhea reported during 2006-2012 were collected from national public emergency reporting system and national viral diarrhea surveillance system respectively and norovirus prevention and control guidelines and related literatures published both at home and abroad were also collected to understand the incidence pattern, etiological characteristics and risk factors of norovirus infection and the problems in norovirus surveillance in China and compare our guideline with other countries' guidelines. Results A total of 56 infectious diarrhea outbreaks caused by norovirus, involving 4979 cases, were reported in China from 2006 to 2013, averagely 89 cases occurred in an outbreak. Norovirus type GⅠand GⅡwere detected. Norovirus detection rate in children hospitalized of norovirus infection in sentinel surveillance hospitals increased from 11.2% in 2007 to 20.3% in 2011, but it was 15.3% in 2012. Conclusion The numbers of norovirus infection outbreaks and hospitalized cases are in increase in China. It is necessary to improve the sensitivity of outbreak surveillance. The norovirus infection prevention and control measures recommended in this paper might be useful in the prevention and control of norovirus infection in China and for updating the related guideline.
