2014年青岛港前湾港区入境国际航行船舶携带输入性医学媒介生物情况的监测分析

Surveillance of introduced medical vectors carried by entry international ships at Qingdao port in 2014

目的系统了解青岛港前湾港区入境国际航行船舶携带输入性医学媒介生物的情况,为制定有效的控制措施提供科学依据。方法在检疫锚地对入境的国际航行船舶携带输入性的鼠类、蚊类、蝇类、蜚蠊类进行调查,对采集的样本进行计数、分类和制作,并对结果进行统计分析。结果 2014年共调查323艘次入境国际航行船舶,输入性蚊类阳性率平均为19.8%(20/101);已鉴定确认的蚊种5种。输入性蝇类阳性率平均为83.0%(268/323);已鉴定确认的蝇种8种。输入性蜚蠊阳性率平均为16.4%(53/323);已鉴定确认的蜚蠊3种。输入性鼠类阳性率平均为0.93%(3/323);已鉴定确认的鼠种3种。结论调查证实入境国际航行船舶携带输入性医学昆虫的情况严重,具有阳性率高,种类多,风险大等特点,对此应给予高度关注。

Objective To investigate the condition of introduced medical vectors carried by entry international ships at Qingdao port and provide scientific evidences for control medical vectors. Methods The introduced medical vectors, including rats, mosquitoes, flies and cockroaches on entry ships at quarantine anchorage of Qingdao port were collected and classified. Results 323 entry ships were checked in 2014, which came from 23 different countries and districts of five continents. The average positive rate of ships and the number of species were: 19.8%(20/101)and 5 for mosquitoes, 83.0%(268/323)and 8 for flies, 16.4%(53/323)and 3 for cockroaches, 0.93%(3/323)and 3 for rodent, respectively. Conclusion It indicates the serious condition of medical vectors carried by entry international ships,with the characteristic of high positive rate and variety of species. More attention should be paid to entry international ships carrying the introduced medical vectors.
