Core Viewpoint - The article highlights the emergence of Chikungunya fever in the Tengchong community of Shunde District, Guangdong, emphasizing the local government's proactive measures to combat the spread of the disease through mosquito control efforts [2][4][15]. Group 1: Background and Context - The Tengchong community, with over 800 years of history, recently reported the first case of Chikungunya fever in China, raising concerns about the disease's spread [2][4]. - The region's geographical features, including a high water area (32.6% of 806 square kilometers), contribute to the breeding of mosquitoes, which are the primary vectors for the disease [3][20]. Group 2: Disease Characteristics and Symptoms - Chikungunya fever is transmitted by Aedes mosquitoes and shares symptoms with dengue fever, including high fever and joint pain, but progresses rapidly [4][15]. - Most patients experience mild symptoms and recover within a week, but the disease can lead to long-term joint pain in some cases [5][19]. Group 3: Local Response and Preventive Measures - The local community initiated a "mosquito control battle," organizing over 1,000 workers to eliminate breeding sites and conduct regular inspections [6][10]. - The Shunde District government issued public advisories urging residents to eliminate standing water and take preventive measures against mosquito breeding [10][23]. Group 4: Current Situation and Statistics - As of July 26, Guangdong reported 4,824 local cases of Chikungunya fever, all classified as mild, with no severe cases or deaths reported [15][17]. - The rapid spread of the disease has prompted health authorities to issue warnings and mobilize community efforts to prevent further outbreaks [20][23].

Core Viewpoint - The Beijing Disease Control Center has stated that the risk of local transmission of Chikungunya fever in Beijing is extremely low due to the absence of the primary mosquito vectors, Aedes aegypti and a low proportion of Aedes albopictus, and that the disease is preventable and controllable [1] Group 1: Disease Overview - Chikungunya fever is primarily transmitted through mosquito bites, specifically by Aedes mosquitoes, and is not spread from person to person [1] - Infected individuals typically experience mild symptoms, including sudden fever and joint pain, with most recovering within a week [1] Group 2: Mosquito Species and Behavior - Aedes albopictus, known for its distinctive black body and white markings, is more active during early morning and late evening [2] - This mosquito species breeds in small containers of stagnant water, and its activity is generally limited to a 100 to 200-meter radius from its breeding site [2] Group 3: Mosquito Control Measures - Beijing has conducted two rounds of city-wide mosquito control this summer, with a significant 43% decrease in adult mosquito density compared to the same period last year [3] - The city has designated specific weeks for unified mosquito control activities, focusing on cleaning breeding sites [3] Group 4: Preventive Actions - Recommendations for reducing mosquito breeding sites include removing stagnant water from various containers and cleaning up potential breeding areas [4][5][6] - Specific measures include regularly changing water in plant pots and ensuring that containers are covered to prevent water accumulation [5][6] Group 5: Personal Protection - When outdoors, it is advised to wear light-colored long sleeves and long pants, and to use mosquito repellent containing DEET or Picaridin [7][8] - Travelers should check the mosquito-borne disease situation at their destination and prepare appropriate protective measures [8]

Group 1 - The World Health Organization (WHO) reports that 119 countries and regions have identified the spread of Chikungunya virus, with approximately 5.5 million people at risk, potentially leading to widespread outbreaks that could strain health systems [1] - Several A-share listed companies have made strategic moves in response to the Chikungunya virus, including Ayhuilong, Shuoshi Biology, Aotai Biology, Rendu Biology, and Rainbow Group, who have shared their plans on the stock exchange interaction platform [1] Group 2 - Chikungunya fever is primarily transmitted by Aedes mosquitoes, with symptoms including fever, rash, and joint pain. Measures such as eliminating breeding sites and insect extermination can help interrupt transmission [2] - The Guangdong Province reported a local outbreak of Chikungunya fever linked to imported cases, with 3,645 confirmed cases reported as of July 23, all mild, and 2,018 patients have recovered [2] - The National Disease Control Bureau and the Guangdong Provincial Health Commission have dispatched expert teams to guide and participate in epidemic prevention efforts, focusing on cutting community transmission and preventing the spread of the outbreak [2] Group 3 - Multiple A-share listed companies are developing testing solutions for Chikungunya virus, primarily for research purposes or overseas markets. Ayhuilong's partner company has developed a rapid screening kit, while Shuoshi Biology and Aotai Biology also have testing kits available for research use [3] - Currently, there are no approved Chikungunya testing kits in the domestic market, but the approval process for related testing products is expected to accelerate [3] - Rainbow Group offers a wide range of household insecticide products aimed at mosquito control, including electric mosquito repellent and aerosol insecticides, which utilize high-quality active ingredients recommended by WHO [3]

Core Viewpoint - The recent outbreak of Chikungunya fever in certain southern cities of China has raised concerns, prompting the World Health Organization to issue a warning for countries to prepare for potential spread [1][2]. Group 1: Current Situation - Most Chikungunya fever cases reported are mild, with severe cases and fatalities being rare [2]. - As of July 23, Foshan City has reported a total of 3,645 confirmed cases, all of which are mild, with 2,018 cases having recovered [3]. Group 2: Response Measures - Foshan City has initiated an emergency response, coordinating medical resources to ensure effective treatment for Chikungunya patients [2]. - The city has designated 53 hospitals as treatment centers, equipped with mosquito prevention measures, and has 3,696 mosquito isolation beds available [2][3]. Group 3: Prevention Strategies - Local communities are actively involved in mosquito breeding site elimination, employing a "single-point breakthrough + full-area prevention" strategy to control the outbreak [5]. - Residents are participating as volunteers to inspect and clean up areas with poor sanitation, focusing on eliminating potential mosquito breeding grounds [5].

据世界卫生组织，避免蚊虫叮咬是防止基孔肯雅病毒感染的最佳保护措施，减少基孔肯雅病毒传播的主要 方法是通过控制蚊子媒介和减少蚊子滋生地。 今天(7月21日)17时前后，广东佛山顺德、禅城、南海区卫健局更新基孔肯雅热疫情信息，显示截至7月20 日，佛山累计报告基孔肯雅热确诊病例2285例，均为轻症。 其中，顺德区累计报告基孔肯雅热确诊病例2158例，主要集中在乐从镇、北滘镇、陈村镇。 禅城区累计报告基孔肯雅热确诊病例69例，主要集中在石湾镇街道、张槎街道和祖庙街道。 南海区累计报告基孔肯雅热确诊病例58例，主要集中在桂城街道。 据广东省疾控，基孔肯雅热是由基孔肯雅病毒引起的急性传染病，症状以发热、关节剧痛和皮疹为特征。 名称源自非洲土语，意为"弯脊之痛"，形容患者因关节剧痛弯腰蜷缩的姿态。主要通过感染病毒的伊蚊(埃 及伊蚊或白纹伊蚊)叮咬而传播，目前尚无直接人传人的报道。 2.积极动手灭蚊虫。蚊香、电蚊拍、防蚊喷雾要备好，卫生死角要处理，没有蚊虫的叮咬就没有此类病毒 的传播。 3.个人防护要做好。出门穿浅色长衣长裤，户外树荫草丛少逗留，家里安装纱门纱窗，睡觉时挂蚊帐。 早前报道↓↓ 南方都市报(nddaily)、 ...
