目的分析2005～2010年防城港市登革热监测结果,为登革热流行趋势的预测、预警和制定防治对策提供科学依据。方法收集本市2005～2010年2个监测点媒介伊蚊的监测资料,进行描述性统计分析。结果防城港市的优势蚊种为白纹伊蚊,未发现埃及伊蚊;监测点大部分监测月份伊蚊布雷图指数(BI)均超过5的安全水平,其中水田屯蚊媒密度较高,最高BI达104,企沙街相对较低,最高BI为54,2009年以后企沙街蚊媒密度明显降低;阳性容器以暂时性容器为主;2006年送检的全部成蚊标本未检测到登革热病毒核酸或分离到病毒。结论防城港市在虫媒方面已经具备传播登革热病毒的条件,存在登革热流行的潜在危险,应加强监测、卫生宣教以及改善农村环境。
