自从大规模服用脊髓灰质炎减毒活疫苗以来,麻痹型脊髓灰质炎的发病率在不少地区已较明显下降。对于正常人群免疫状况及其他肠道病毒的传播动态,目前国内外也注意观察研究。为了进一步了解我省肠道病毒传播动态,我们于1973～1976年定期、定点进行肠道病毒观察,以便为今后防治工作提供资料,现将调查情况报告如下。材料与方法一、地区与对象: 选择福州红卫区第二托儿所为观察点,于每年三月份服用灰质炎活疫苗之前,采集7岁以下健康儿童粪便标本一次。1975年6、9、12月份各采一次,标本放置冰壶即送检。
The incidence of paralytic poliomyelitis has dropped significantly in many areas since the large-scale live-attenuated polio vaccine. For the normal population of immune status and other gut virus transmission dynamics, at home and abroad also pay attention to observation and research. In order to further understand the dynamics of the transmission of enterovirus in our province, we conducted regular and fixed-point enterovirus observations from 1973 to 1976 in order to provide information for future prevention and treatment work. The investigation is reported as follows now. MATERIALS AND METHODS I. REGIONS AND OBJECTS: The second nursery in Hongwei District of Fuzhou was selected as the observation point. Before the live gray-calorie vaccine was taken in March of each year, stool samples of healthy children under 7 years old were collected. In 1975 6, 9, December each mining time, specimens placed curling is submitted for inspection.
