丹东口岸朝鲜籍人员传染病监测及防控策略

目的 通过对丹东口岸入境的朝鲜籍人员进行健康体检,了解丹东口岸朝鲜籍人员传染病患病率情况,并根据流行病学调查结果推断朝鲜国内传染病流行情况,为丹东口岸卫生检疫把关提供科学依据。方法 对2015—2017年由丹东口岸入境的朝鲜籍人员采用胸部X线、形态学检测、分子生物学及免疫学等方法检测肺结核、乙型病毒性肝炎、梅毒、疟疾等传染病,对监测资料进行统计分析。结果 2015—2017年共体检监测朝鲜籍入境人员18 494人,检出传染病557例,总检出率为 3.01 %;其中乙型病毒性肝炎466例、肺结核33例、梅毒57例、恶性疟1例;其中最多的是劳务人员16 074名(86.91 %),其次是商务人员1 354名(7.32 %),涉外婚姻544名（2.94%）,留学人员473名(2.56 %)。检出率最高的三种人群分别为商务人群、劳务人群、涉外婚姻人群,检出率依次为4.28%、2.99%和2.76%;20~30岁是传染病检出例数最多的人群。结论 丹东口岸朝鲜籍入境人员乙型病毒性肝炎、梅毒及肺结核患病率较高,朝鲜国内存在肺结核和肝炎高流行性可能。

Surveillance and control strategy of infectious diseases of North Koreans at Dandong Port

Objective To understand the incidence of infectious diseases in North Korean travelers,so as to provide the evidence for formulating the disease control strategy at China-Democratic People’s Republic of Korea (DPRK) border by performing health inspection on North Korean international travelers at Dandong Port. Methods Hepatitis B, pulmonary tuberculosis, syphilis and malaria were tested by using immunology and molecule biology assays among North Korean travelers coming through Dandong Port from 2015 to 2017, and the data were analyzed statistically. Results A total 18 494 North Korean travelers were tested for infectious diseases at Dandong Port, 2015-2017, and 557 cases of infectious diseases were found with the general detection rate of 3.01%. The numbers of detected cases of hepatitis B, tuberculosis, syphilis, and Plasmodium falciparum infection were 466,33,57, and 1,respectively. The tested North Korean travelers included 16 074 labor workers (86.91%), 1 354 businessman(7.32%), 544 foreign marriages (2.94%), and 473 oversea students(2.76%). Three highest occupations of the people with infectious diseases were businessman,labor workers and foreign marriages, and the detection rates were 4.28%,2.99%and 2.76% respectively. The age group of 20-30 years was the highest prevalence age group. Conclusion The prevalence of infectious diseases in North Korean travelers is high, which demonstrates that the prevalence rates of hepatitis B and pulmonary tuberculosis may be high in DPRK.
