摘    要:目的调查了解诺如病毒引起的感染性腹泻暴发疫情的流行病学特点及传播途径,为制定预防控制对策提供依据。方法采用流行病学现场调查和统计分析方法、轮状病毒抗原检测、诺如病毒RNA检测以及细菌分离培养常规方法。结果本次疫情共发生病例444例,其中犯人360例,同时波及周围村屯及矿区工人;首例9月18日,末例10月7日,高峰在9月25~26日,不同区域流行时间不一致;病例分布有一定的区域聚集性;病例以成人为主;临床表现较轻,病程多在2~3天,有一定自限性;血常规多正常,大便常规均无异常;26份粪便标本中24份诺如病毒RNA检测阳性,1份轮状病毒抗原检测阳性,3份同时检出诺如病毒和产毒性大肠埃希菌。结论证实此为一起由诺如病毒引起的感染性腹泻暴发疫情,传播途径主要系生活接触传播所致。

关 键 词:诺如病毒  感染性腹泻  暴发

Abstract:Objectives To investigate and reveal the epidemiological characteristics and the mode of transmission of an infectious diarrhea outbreak due to Norovirus,and to provide scientific evidence for control strategies development.Methods Data was collected and analyzed using the methods of epidemiological investigation and statistics,and samples were tested with assays of viral antigen detection,RNA detection of Norovirus and bacterial culture and isolation.Results A total of 444 cases were observed,of which 360 were prisoners,while the rest were villagers and mine workers living in the neighborhood.The first case was reported on September 18 and the last one on October 7,with an incidence peak between September 25 and 26.Case clustering by areas was observed and the epidemic periods varied in different areas in this outbreak.Most of the cases were adults with mild signs and symptoms which were self-limited within 2 or 3 days from the onset day onwards.Negative blood routine tests were found in most of the cases and none of them had positive stool routine tests.24 out of 26 fecal samples tested positive for Norovirus RNA while another one for rotavirus antigen.And among those samples,three tested positive for both Norovirus and Enterotoxigenic Escherichia Coli.Conclusion Norovirus was confirmed as the cause to this infectious diarrhea outbreak,which was mainly transmitted by close contacts.
Keywords:Norovirus  Infectious diarrhea  Outbreak
