Core Points - Chikungunya fever is a mosquito-borne disease caused by the Chikungunya virus, primarily transmitted through bites from infected Aedes mosquitoes, with no direct human-to-human transmission reported [1] Transmission - The transmission route of Chikungunya fever is similar to that of dengue fever, primarily through bites from infected Aedes mosquitoes, particularly the Aedes albopictus, which is widely distributed in urban and rural areas [4] - Aedes mosquitoes typically bite during the day, with peak activity occurring 1-2 hours before sunrise and 2-3 hours before sunset [4] - The virus can survive in mosquitoes for an extended period after they bite an infected person or animal, with a replication period of 2 to 10 days before it reaches the salivary glands [4] Geographic Distribution - Chikungunya fever is prevalent in tropical and subtropical regions, with local transmission cases reported in 119 countries and regions globally, particularly active in Southeast Asia, South Asia, Africa, and parts of the Americas [5] - Recent local transmission cases have been reported in Guangdong Province, China, following imported cases [5] Clinical Symptoms - The incubation period for Chikungunya fever ranges from 1 to 12 days, with most cases occurring between 3 to 7 days [6] - Symptoms include sudden high fever (≥39°C), severe joint pain (especially in the wrists), and a rash that typically appears 2-3 days after fever onset [6] - The overall duration of the illness is usually 5 to 7 days, with most patients recovering within a week, although joint pain may persist in some cases [6] Prevention Measures - Effective prevention includes mosquito control measures, such as avoiding areas with high mosquito activity, using mosquito nets, and installing screens on windows and doors [8] - Eliminating breeding sites for Aedes mosquitoes by removing standing water and using insecticides in areas where water cannot be removed is crucial [9] - Personal protective measures include wearing light-colored long-sleeved clothing, avoiding mosquito breeding areas, and using repellents [10] - Travelers are advised to monitor health for 14 days after returning from areas with Chikungunya outbreaks and to seek medical attention if symptoms arise [12]

当地时间22日，世界卫生组织发布消息称，近期，与印度洋地区相关的新一轮基孔肯雅热疫情已蔓延至 欧洲及其他大洲，该组织紧急呼吁各国立即采取行动，避免20年前那场席卷全球的基孔肯雅病毒疫情重 演。 当天，世卫组织医学官员在日内瓦表示，全球119个国家的约56亿人生活在该病毒威胁之下。 该官员表示："我们正在目睹历史重演。" 该官员还将其与2004至2005年的该病疫情进行对比——当时疫情最初集中在小岛地区，影响近50万人， 随后扩散至全球。 世卫组织介绍称，本轮疫情始于2025年初，重灾区仍是此前受创的印度洋岛屿：留尼汪、马约特和毛里 求斯，目前留尼汪岛上已有约三分之一的人口感染。病毒现正向马达加斯加、索马里、肯尼亚等地传 播，并在东南亚（包括印度）出现流行态势。 消息还称，令人担忧的是，欧洲输入性病例激增，且已出现本地传播。自5月1日以来，法国本土已报告 约800例输入性基孔肯雅热病例，法国南部多个地区已确认12起本地传播事件，即感染者并未到过流行 区，而是被当地蚊虫叮咬所致。 此外，意大利近期也报告了一例本地感染病例。 通过蚊子传播 本轮疫情始于2025年初 正在全球多地呈流行趋势 感染后有哪些症状？ 世卫组 ...
