人民网北京12月16日电 （记者乔业琼）据长沙疾控微信公众号消息，寒冷的冬天，蚊子似乎从生 活中消失了，但它们并未走远。当环境温度低于10℃时，蚊子便会寻找合适的地方，进入一种类似"休 眠"的状态——不吃不喝也不动，停止发育、吸血和繁殖，这种形态的蚊子被称为越冬蚊。 越冬方式 不同种类的蚊子有着截然不同的越冬策略。它们会根据自身特点和环境条件，选择合适的生命阶段 度过寒冬。 致倦库蚊、中华按蚊主要以成蚊形态越冬。它们在寒冷来临前会集中吸血，将能量转化为脂肪储存 在体内。这些脂肪不仅提供能量，还能降低体内组织的冰点，帮助它们耐受低温。致倦库蚊会躲进地下 室、楼梯间、家具缝隙等温暖避风的地方。而中华按蚊越冬场所主要在稻草堆、杂草堆中。 白纹伊蚊则选择以卵的形式度过冬天。这种蚊子就是我们常说的"花蚊子"，它把卵产在各种小型积 水容器的内壁上，如花盆托盘、废旧轮胎、瓶罐等。这些卵具有极强的抗寒和抗干燥能力，即使积水干 涸，卵也能存活数月，等待春雨来临、积水重现时孵化。 还有一些蚊子如骚扰阿蚊，会以幼虫形态越冬。这些幼虫躲在水坑、污水沟等不易完全冻结的水体 中，暂停发育，静待春暖花开。 藏身之处 越冬蚊藏身的选择非常" ...

Core Viewpoint - The emergence of local outbreaks of Chikungunya fever in certain regions of China has prompted a rapid response from health authorities, emphasizing the importance of mosquito control and public awareness to prevent further spread [2][5]. Group 1: Disease Overview - Chikungunya fever is an acute mosquito-borne viral infection primarily transmitted by Aedes mosquitoes, particularly Aedes aegypti and Aedes albopictus [3]. - Symptoms typically appear 3 to 7 days after infection, with common signs including high fever and joint pain, especially in small joints like wrists and ankles [3]. - Most patients recover within a week, but approximately 30% to 40% may experience prolonged joint pain [3]. Group 2: Prevention Measures - Key prevention strategies include eliminating adult mosquitoes, removing breeding sites, and avoiding mosquito bites [4]. - Personal protective measures involve wearing light-colored, long-sleeved clothing and using effective mosquito repellent on exposed skin [4]. - Environmental management includes regular cleaning of potential water accumulation sites and using approved insecticides indoors [4]. Group 3: Travel Advisory - Travelers should check for Chikungunya fever outbreaks at their destinations and take appropriate precautions [5]. - Post-travel self-monitoring for symptoms such as fever and joint pain is advised, with immediate medical consultation recommended if symptoms arise within two weeks [5].
