目的了解大连口岸出入境人员病毒性肝炎感染情况,为实施口岸传染病监测,预防和控制病毒性肝炎的流行,做好旅行卫生保健工作提供科学依据。方法对2003年2月-2004年1月在大连口岸进行体检的出入境人员,采用酶联免疫吸附试验(ELISA)检测血清 HAV-IgM,HBV 标志物(两对半),同时检测血清 ALT,并对其结果进行统计学分析。结果 29 746名出入境人员中HAV—IgM 阳性者仅一例;乙肝病毒感染者1 332例,阳性率4.48%。其中远洋船员乙肝病毒感染阳性率为6.2%,远洋渔工乙肝病毒感染阳性率高达9.32%,而无一例 HAV-IgM 阳性者。结论应加强对远洋船员(尤其是远洋渔工)病毒性肝炎的监测。采取相应的预防措施,提供卫生保健知识,控制乙型病毒性肝炎“隐性”感染。
Objective To understand the status of viral hepatitis infection among persons entering and exiting Dalian Port, and to provide a scientific basis for the implementation of surveillance and prevention of communicable diseases at port and the prevention and control of the prevalence of viral hepatitis.

Results Only 29746 HAV-IgM positive persons were enrolled in entry and exit. Only 1 332 cases were infected with hepatitis B virus, the positive rate was 4.48%. Among them, the positive rate of hepatitis B virus infection by ocean-going crew was 6.2%, and the positive rate of hepatitis C virus infection by oceanic fishermen was as high as 9.32%, but none of them was positive for HAV-IgM. Conclusion Monitoring of viral hepatitis in offshore vessels (especially offshore fisheries) should be strengthened. Take appropriate preventive measures to provide health care knowledge, control of hepatitis B “hidden” infection.
