广西口岸出入境人员登革热流行病学特征分析及预防控制措施

Epidemiologic Status on Dengue Fever at Guangxi Ports and its Strategies of Prevention and Control

〔目的〕了解广西各口岸出入境人群中登革病毒感染状况及流行病学特征,为广西口岸登革热的防治提供科学依据。〔方法〕对广西口岸890名出入境人员进行登革病毒IgG/IgM抗体血清学监测。〔结果〕广西口岸出入境人员登革病毒IgG抗体总阳性率为5.17%;外籍人员阳性率为8.73%,中国籍人员阳性率为0.52%,两者差异有显著性(P<0.001);外籍人员中以柬埔寨籍人员阳性率最高,其次为澳大利亚籍人员,不同国籍人员间阳性率进行比较,差异有显著性;留学生、商人、船员阳性率分别为5.62%,6.45%,8.49%,3者间差异无显著性(P=0.564),而与其它职业人员相比较,差异均有显著性(P<0.01)。〔结论〕广西口岸出入境人群对登革病毒感染普遍缺乏免疫力,登革热易在口岸传播和流行;东南亚国家人员、留学生、商人、船员是口岸登革热监测的高危人群;口岸登革热的预防控制需要实施加强宣传工作,开展高危人群监测,媒介监测和完善网络监测系统等综合应对措施。

Objective To understand dengue virus infection and epidemic status of entry-exit personnel at Guangxi ports, and to provide scientific evidence for dengue fever prevention and control. Method Serum samples of dengue virus IgG/IgM antibody was analyzed in 2006 at Guangxi ports. Result The total positive rate of entry personnel was 5.17%, the total positive rate of entry foreigners was 8.73%, that of chinese was 0.52%, there was significant difference betweet them （P 〈 0.01 ）. Of foreigners, the positive rate of Cambodia, was the highest, the next was Australia, there was significant difference between different nationality （P〈 0.01 ）. The positive rates of foreign student, businessman and sailor was 5.62%,6.45% and 8.49% respectively, there was no significant difference between them （P = 0.564）.There was significant difference between other occupation population （P 〈 0.01 ）. Conclusion The people is subject to Dengue fever and this disease is particularlly prevail in the entry-exit personnel lacking of immunity at Guangxi ports. We should pay more attention to the high risk group, such as personnels from southeast Asia, foreign students, businessmen and sailors. It is important to strengthen propagation for Dengue fever prevention and control, and develop surveillance for high risk group. The vector monitoring and network surveillance system should be built at Guangxi ports.
