中国内地首起输入聚集性寨卡病毒病疫情的处置分析

Analysis on the disposal of the first imported clustered cases of Zika virus disease of China's Mainland

目的 2016年2月,检验检疫机构在皇岗口岸检疫发现全国第3例输入性寨卡病毒感染病例,通过联防联控机制发现并成功处置全国第4、5例输入性寨卡病毒感染病例。分析此次疫情,为今后防控重大输入性疫情提供参考。方法详细回顾第3例输入性寨卡病毒病病例的入境检疫过程,对同行32名密切接触者的排查及追踪过程,后续通过联防联控机制发现并处置第4、5例寨卡病毒病病例的过程。结果 3名输入性寨卡病毒病病例有共同境外暴露史,构成中国内地首起输入聚集性寨卡病毒病疫情。依托联防联控机制,疫情得到成功处置,未造成境内传播。结论卫生检疫是防范境外疫情输入的有效公共卫生措施,应加强专业流行病学调查工作,畅通疫情通报途径,强化"境外-口岸-境内"联防联控控制建设。

Objective In February 2016,the third Zika virus disease case in China's Mainland was found through quarantine screening at Huanggang port,and the fourth and fifth cases were found through the follow-up joint prevention measures.To analyze these imported clustered cases was helpful to provide guidance for the prevention and control of this severe imported clustered cases.Methods The entry quarantine process of the third imported Zika case was revised,the investigation and tracking process of 32 close contacts and the follow-up process of discovering and disposing of the fourth and fifth Zika cases through the joint prevention and control mechanism.Results These three cases,as the first imported clustered cases of Zika virus disease of China's Mainland had the same oversea epidemic exposure history,and were cured successfully without causing local spreading.Conclusion Health quarantine is effective on preventing overseas epidemics from being imported into China's Mainland.Professional epidemiological investigation should be strengthened,information notification mechanism should be smoothed,and'overseas-portdomestic'joint prevention and control mechanism should be strengthened.
