目的了解云南中老口岸出入境人员登革病毒(dengue virus,DENV)抗体和基孔肯雅病毒(chikungunya virus,CHIKV)抗体水平,为制定有效登革热和基孔肯雅热防治对策提供依据。方法在中老磨憨口岸采集出入境体检人员血清,采用酶联免疫吸附试验检测DENV和CHIKV IgG抗体,对检测结果进行统计分析。结果共采集健康体检人员血清182份,其中有42份DENV或CHIKV IgG抗体阳性,总阳性率为24.08%(42/182)。DENV IgG阳性率为1.65%(3/182),CHIKV IgG阳性率为21.42%(39/182);检测阳性率差别和年龄、性别、职业相关,51~60岁、男性、后勤人员的阳性率高于其他人员。结论中老磨憨口岸健康人群中存在DENV和CHIKV的隐性感染,应加强口岸的登革热、基孔肯雅热疫情的监测。
Objective To understand the antibody levels of dengue virus (DENV) and chikungunya virus (CHIKV) in entry and exit personnel at the middle and old ports in Yunnan Province, and to provide evidence for effective prevention and treatment of dengue fever and chikungunya fever. Methods The sera of immigrant medical staff were collected at the Mogan port of Middle-old, and the antibodies of DENV and CHIKV IgG were detected by enzyme-linked immunosorbent assay (ELISA). The statistical analysis was made on the test results. Results A total of 182 serum samples were collected from healthy medical staffs, of which 42 were positive for DENV or CHIKV IgG with a total positive rate of 24.08% (42/182). The positive rate of DENV IgG was 1.65% (3/182), and the positive rate of CHIKV IgG was 21.42% (39/182). The positive rate of CHIKV IgG was positively correlated with age, sex, occupation, age at 51 ~ 60, male and logistic staff Higher than other people. Conclusion There are DENV and CHIKV recessive infection in the healthy population of Mochian port in Middle-aged and old, and dengue fever and chikungunya fever in port should be strengthened.
