【摘要】：目的了解成都市健康儿童不同流行期手足口病病毒携带情况,为手足口病防控工作提供技术支持。方法采用分层随机抽样方法,抽取成都市120所托幼机构的758名健康托幼儿童,在手足口病发病高峰期、低谷期采用RTPCR检测健康儿童肠道病毒类型。结果流行期健康儿童肠道病毒阳性率为8.93%,非流行期阳性率为2.13%,差异有统计学意义(χ~2=17.70,P0.01)。流行期健康儿童其他肠道病毒阳性率为7.44%,高于非流行期(2.13%)(χ~2=12.30,P0.01)。流行期时城区健康儿童肠道病毒携带率(13.13%)高于郊区(2.89%)(χ~2=10.47,P=0.001);健康儿童其他肠道病毒携带率高于确诊病例(χ~2=28.26,P0.01),CA16,EV71携带率低于确诊病例(P值均0.01)。结论加强流行期城区托幼机构手足口病防控工作,积极开展手足口病健康儿童其他肠道病毒病原型别监测研究,警惕流行期健康儿童EV71携带情况,对控制手足口病流行具有重要意义。
[Abstract]:Objective to investigate the prevalence of HFMD virus in healthy children in Chengdu and to provide technical support for the prevention and control of HFMD. Methods 758 healthy toddlers in 120 kindergartens in Chengdu were selected by stratified random sampling. At the peak of hand, foot and mouth disease, Results the positive rate of enterovirus in healthy children during epidemic period was 8.93, and that in non-epidemic period was 2.13.The difference was statistically significant (蠂 ~ 2 ~ 2 ~ (17. 70) P ~ (0.01)). The positive rate of other enterovirus in healthy children in epidemic period was 8.93%. The rate was 7.44, which was higher than that in non-epidemic period (蠂 ~ 212.30 / P 0.01), and was higher than that in suburban area (蠂 ~ (2) ~ (2)) ~ (10.47) P ~ (0.001) and other enterovirus carriers in healthy children were higher than those in confirmed cases (蠂 ~ (2) 28.26 ~ (28) P _ (0.01) P ~ (0.01)) compared with those in confirmed cases (P < 0.01). Prevention and control of hand, foot and mouth disease in child-care institutions in urban areas during the epidemic period, It is of great significance to study the archetypes of other enterovirus diseases in healthy children with hand foot and mouth disease and to be alert to the prevalence of EV71 in healthy children during the epidemic period.
