肠道病毒健康人群的带毒率为10.11%,农村人群明显高于城、近郊区。在阳性标本中Polio疫苗病毒占5.3%,其它肠道病毒占94.7%,以ECHO_(11)型为流行优势株。肠道病毒的型号分布有地区差异,但与性别无关。病毒主要携带者仍为学龄前儿童,并随年龄增长带毒率逐渐降低。此文提示:北京市Polio病毒带毒虽日趋减少乃至消失,但患者中分到野病毒却不容忽视。此外,由于对引起麻痹型类脊灰炎病毒的广泛检出,因此我们在抓计免工作的同时,需密切注意其它肠道病毒在流行病学上的作用,加强监测,防患于未然。
Enterovirus infection rate of healthy people was 10.11%, rural population was significantly higher than the city, the suburbs. Among the positive samples, Polio vaccine virus accounted for 5.3% and other enterovirus accounted for 94.7%. ECHO_ (11) was the predominant strain. There are regional differences in the distribution of enteroviruses, but not sex. The main carriers of the virus are still preschool children, and with age, the incidence of poisoning gradually decreases. This article suggests: Beijing Polio virus poisoning has diminished or even disappeared, but patients assigned to the wild virus can not be ignored. In addition, due to the wide range of detection of paralytic poliovirus, we need to pay close attention to the epidemiological role of other enteroviruses while monitoring work-for-death and strengthening surveillance to prevent it.
