Group 5: Preventive Measures - The Beijing CDC has indicated that the risk of local infection in Beijing is extremely low due to the absence of Aedes mosquitoes, and effective mosquito control measures can mitigate the risk [14][15]. - Recommendations for prevention include wearing light-colored long sleeves and using effective mosquito repellents, especially in areas with high mosquito density [16].

"中国既往没有过输入性基孔肯雅热引发大流行的案例，对该病的基础免疫力缺失，因此病毒传播会快 于其他流行区域。"张文宏向记者解释称。 不过即便如此，他认为，如果及时采取有效迅速的措施，目前南方部分地区应该仍处于控制疫情的有效 窗口期，仍能阻止感染风暴的进一步形成并阻止病毒向周边区域扩张。 根据广东省佛山市各区最新的通报，截至7月24日，佛山市5个区已累计报告基孔肯雅热确诊病例超过 4000例。目前，佛山当地已经对感染患者采取了防蚊隔离措施。 据广东省佛山市各区最新的通报，截至7月24日，佛山市5个区已累计报告基孔肯雅热确诊病例超过4000 例，其中顺德区报告确诊病例3627例，均为轻症病例。据智通财经，目前，广州、阳江、湛江等地均出 现了基孔肯雅热病例。世界卫生组织25日警告，基孔肯雅热病毒正在全球多地扩散，已有119个国家报 告病例，约550万人面临感染风险。 针对我国近期南方部分地区突然增多并出现外溢的基孔肯雅热病例，国家传染病医学中心主任、复旦大 学附属华山医院感染科主任张文宏教授首次发声。他接受记者采访时解释了为何此次病毒在我国南方部 分地区传播较快。 对此，张文宏表示，人也是该病毒的传染源，会帮助病毒 ...

为什么今年佛山疫情规模比以往都大？如何防范基孔肯雅热疫情呢？本台记者独家专访了中国疾控中心病媒生物首席专家。 央视网消息：根据广东省佛山市各区最新的通报，截至7月24日，佛山市5个区已累计报告基孔肯雅热确诊病例超过4000例。很多人都对这 个念上去非常拗口的蚊媒传染病比较陌生，其实我国早在2008年就首次发现输入性病例，此后在2010年和2019年等都曾发生过输入病例引起的 本地传播疫情，但规模都非常小。 佛山今年疫情规模为何会超以往？正常吗？ 很多网友表示，广东地区之前都是零散的个例，今年为何会突然出现大范围地快速传播？ 专家介绍，有多重原因导致，首先是外部环境基孔肯雅热流行强度高，世界卫生组织专家本月22日就已发出警报，目前已有119个国家和 地区发现基孔肯雅病毒传播情况，提醒各国做好应对准备，避免疫情大规模暴发。 中国疾控中心病媒生物首席专家 气候变化与健康全球联盟主席 刘起勇：世界卫生组织警报是根据全球基孔肯雅热的暴发流行的总体形势 做出的，他们做了一个比较。10年前在印度洋的基孔肯雅热大暴发，它形成的规模和造成的损失总体来讲目前是跟它相似的，尽管现在还没有 达到当年的水平，当年（全球）是50万人感染 ...

Core Points - The article emphasizes the increased risk of vector-borne diseases during summer outdoor activities, particularly from mosquitoes and ticks, which can lead to illnesses such as dengue fever and Lyme disease [2][3] - The provincial disease control center has released a scientific prevention guide to help individuals stay healthy while enjoying outdoor activities [2] Summary by Category Vector-Borne Diseases - Common vector-borne diseases include dengue fever and chikungunya, which have early symptoms similar to common cold or flu, making them easy to overlook [2] - Symptoms of these diseases include high fever, headache, muscle and joint pain, and rash [2] - Tick bites may initially cause mild local reactions but can lead to serious symptoms if tick-borne diseases are contracted, including fever, headache, fatigue, and in severe cases, confusion and bleeding tendencies [2][3] Prevention Measures - To prevent dengue and chikungunya, it is advised to eliminate standing water in household items like vases and buckets, and to keep outdoor areas clean to avoid water accumulation [3] - Wearing long sleeves and pants, preferably in light colors, and using mosquito repellent on exposed skin are recommended when outdoors [3] - Installing screens on doors and windows and using mosquito nets while sleeping can provide physical barriers against mosquitoes [3] - For tick prevention, it is important to clear weeds and debris around gardens, avoid prolonged stays in tick-infested areas, and check for ticks on oneself and pets after outdoor activities [3]

日前，广东省佛山市召开新闻发布会称，为应对基孔肯雅热疫情形势发展，佛山已指定53家二级及 以上医院作为定点收治医院，同时将防蚊隔离床位从3696张扩容至7220张，为确诊病例提供诊疗和 住院治疗服务。 7月23日，在国家卫健委举行的新闻发布会上，中国疾控中心介绍，近期，我国南方个别城市发生基 孔肯雅热输入疫情并引发本地传播。但强调基孔肯雅热可防可控可治，主要通过伊蚊叮咬传播，没有 人传人迹象。 截至7月24日，佛山市基孔肯雅热感染已超3600例，疫情仍处在高位平台期，但尚未发现本地续发 病例，疫情输入风险总体可控，且患者均为轻症。一些人对于患者为何需要隔离产生疑惑，既然不会 人传人，为何仍需采取隔离措施？ 对此，相关专家对第一财经记者表示："基孔肯雅热的传播途径是人-蚊-人，虽然病毒不会直接人传 人，但人也是传染源——人感染病毒后大部分患者都会出现病毒血症，若不进行防蚊隔离，叮咬了感 染者的蚊子体内病毒增殖，再通过叮咬他人，形成社区传播。由于病毒传播速度极快，将患者隔离， 能有效减少病毒进一步传播扩散的风险。" 2025.07. 25 本文字数：929，阅读时长大约2分钟 作者 | 第一财经 钱童心 国家感染 ...

Core Viewpoint - The recent outbreak of Chikungunya fever in Foshan, Guangdong, has surpassed 4,000 confirmed cases, marking a significant increase compared to previous years, attributed to various factors including climate conditions and the presence of the Aedes mosquito vector [1][2][4]. Group 1: Outbreak Scale and Causes - The scale of the Chikungunya outbreak in Foshan this year is unprecedented, with multiple factors contributing to its rapid spread, including high global transmission rates and favorable local environmental conditions for mosquito breeding [2][4]. - The World Health Organization has issued warnings regarding the global situation of Chikungunya, noting that 119 countries and regions have reported cases, which has implications for local outbreaks in China [2][4]. Group 2: Transmission and Symptoms - Chikungunya is primarily transmitted through the Aedes mosquito, and not through human-to-human contact, raising concerns about the effectiveness of preventive measures [5][6]. - Symptoms of Chikungunya include severe joint pain, which can last from weeks to months, with a small percentage of cases experiencing prolonged symptoms [7][9]. Group 3: Preventive Measures - In regions without confirmed cases, general preventive measures against mosquito breeding should be implemented, while areas with outbreaks require more intensive mosquito control and personal protection efforts [11]. - Collective actions, such as synchronized use of mosquito repellent products, can enhance the effectiveness of mosquito control efforts in communities [12][17].

据《BMC研究笔记》发表的"利用半解析方法模拟宿主内基孔肯雅病毒与免疫系统的动态关系"研究文章，基孔肯雅热的传播指数R0 值约为7，是登革热的两至三倍，传播速度较快。不过，专家表示，R0值也会受当地的环境影响而波动。 国家感染性疾病临床研究中心主任、深圳市第三人民医院院长卢洪洲教授向第一财经记者解释称，所谓的"病毒血症"一般出现在患 者感染病毒后的1-5天，可通过检测的方式来确定患者体内血液中是否存在病毒。 另一位传染病专家对第一财经记者表示，对于感染者的密接人员，目前主要是以家庭密接者，或是暴露在相同风险中的人员作为隔 离对象。 日前，广东省佛山市召开新闻发布会称，为应对基孔肯雅热疫情形势发展，佛山已指定53家二级及以上医院作为定点收治医院，同 时将防蚊隔离床位从3696张扩容至7220张，为确诊病例提供诊疗和住院治疗服务。 7月23日，在国家卫健委举行的新闻发布会上，中国疾控中心介绍，近期，我国南方个别城市发生基孔肯雅热输入疫情并引发本地 传播。但强调基孔肯雅热可防可控可治，主要通过伊蚊叮咬传播，没有人传人迹象。 截至7月24日，佛山市基孔肯雅热感染已超3600例，疫情仍处在高位平台期，但尚未发现本地续发 ...

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 ...
