目的研究肠道病毒在健康人群及环境水体中的分布情况,为指导脊髓灰质炎疫苗衍生病毒(VDPV)事件的调查处理,以及研究水中肠道病毒对公众健康带来的风险提供依据。方法选择新疆喀什市作为监测点,在同一个月份内采集150份健康人群粪便标本及1份污水处理厂入水口水样进行肠道病毒分离和鉴定。结果 150份粪便标本中,检出肠道病毒(EV)15株,阳性率10.0%;环境污水中检出肠道病毒(EV)11株,其中脊髓灰质炎病毒(PV)2株,埃可病毒(ECHOV)9株。结论新疆喀什市健康人群及环境污水中肠道病毒广泛存在,环境污水监测能了解脊髓灰质炎疫苗衍生病毒(VDPV)流行分布范围,有效指导VDPV事件的调查处理,同时也为进一步研究污水中肠道病毒为公众健康带来的风险提供重要的背景信息。
Objective To study the distribution of enteroviruses in healthy and environmental water and to provide evidence for the investigation and treatment of poliovirus-derived virus (VDPV) events and the public health risks of enterovirus in water. Methods Kashi City in Xinjiang was selected as the monitoring point. During the same month, 150 healthy stool samples and 1 water sample from the sewage treatment plant were collected for intestinal virus isolation and identification. Results Of the 150 stool specimens, 15 strains of enterovirus (EV) were detected with a positive rate of 10.0%. 11 strains of enterovirus (EV) were detected in environmental water samples, including 2 poliovirus (PV) Nine viruses (ECHOV). Conclusion The population of healthy people in Kashgar and the enterovirus in environmental sewage are widespread. Monitoring of environmental sewage can understand the epidemic distribution of poliovirus vaccine (VDPV) and effectively guide the investigation and treatment of VDPV. In addition, Road viruses provide important background information on the risks posed by public health.
