夏季气温攀升、降雨量增多，蚊虫活动愈发活跃。中国疾控中心16日发布专门健康提示，提醒公众 夏季蚊媒传染病传播风险显著增加，要警惕登革热和基孔肯雅热，做好清除蚊虫孳生地、防蚊灭蚊等预 防举措。 什么是蚊媒传染病？"小"虫子可能带来哪些"大"麻烦？人类和蚊虫的斗争是否随着气候环境变 化，"打怪升级"？ 不可小看的蚊子—— 使人寒战、贫血的疟疾，使人抽搐、意识障碍的乙脑，使人高烧、全身剧痛、皮疹的登革热……蚊 子虽小，却可能通过叮咬传播多种致命传染病。 新中国成立以来，我国蚊媒传染病发病率、死亡率显著下降，在2021年宣布消除了疟疾。 然而，全球化时代的"蚊虫迁徙"和气候环境发生的剧烈变化给蚊媒传染病防控带来了全新挑战。 世界卫生组织公布数据显示：2024年，全球报告登革热病例数为1400万，创历史新高。 蚊子的跨境流动，使我国亦面临较大"外防输入"压力。昆明海关公布信息显示，云南等边境地区不 仅有跨边境输入的疟疾病例，也有感染性按蚊飞越国境传播的风险。而气候变暖、降水增多等气候变 化，为登革热媒介伊蚊，提供了更加适宜生存的条件。 刘起勇指出，气候、环境、自然灾害、人类的生产生活方式等因素都会影响蚊媒传染病的传播。 ...
