Core Viewpoint - The risk of mosquito-borne diseases, particularly dengue fever and chikungunya, is significantly increasing during the summer due to rising temperatures and increased rainfall, prompting health authorities to issue warnings and preventive measures [1][3]. Group 1: Current Situation and Challenges - The incidence and mortality rates of mosquito-borne diseases in China have significantly decreased since the founding of the People's Republic of China, with malaria being declared eliminated in 2021 [2]. - Globalization and climate change present new challenges for the prevention and control of mosquito-borne diseases, with the World Health Organization reporting a record high of 14 million dengue cases globally in 2024 [3]. - Cross-border movement of mosquitoes poses a significant "external input" risk for China, particularly in border areas like Yunnan, where there is a risk of disease transmission from neighboring countries [3][4]. Group 2: Specific Diseases and Symptoms - Dengue fever and chikungunya are highlighted as key concerns, with recent reports of local outbreaks in southern provinces of China, including a recent chikungunya case in Foshan, Guangdong [5]. - Chikungunya is transmitted by Aedes mosquitoes and has a typical incubation period of 1 to 12 days, with symptoms including sudden fever, rash, and joint pain, which can be severe [5][6]. - Most chikungunya cases are mild, with recovery typically occurring within a week, and severe cases and fatalities are rare [5]. Group 3: Preventive Measures - Four key preventive measures are recommended to reduce the risk of infection: 1. Eliminate mosquito breeding sites by regularly cleaning areas where water can accumulate [8]. 2. Create a "mosquito-free" environment through personal protective measures, such as wearing long sleeves and using mosquito repellent [8]. 3. Stay informed about outbreaks in travel destinations, especially in regions where dengue and chikungunya are prevalent [8]. 4. Seek medical attention promptly if symptoms arise, providing travel and mosquito exposure history to healthcare providers [8].

Core Points - The report highlights a local outbreak of Chikungunya fever in Shunde District, Foshan, Guangdong Province, with a total of 478 confirmed cases as of July 15 [1][2] - Chikungunya fever is a mosquito-borne disease similar to dengue fever, primarily transmitted by Aedes mosquitoes, with symptoms including fever, joint pain, and rash [2][3] - The disease has been reported in various regions of China since 2008, mainly in southern provinces, with no significant northward spread of local transmission observed [3][4] Summary by Sections Outbreak Details - As of July 15, Shunde District reported 478 confirmed cases of Chikungunya fever, primarily in Lecong, Beijiao, and Chen Village, all classified as mild cases [2] - The disease is caused by the Chikungunya virus, first identified in Tanzania in 1952, and has been found in various countries across Africa and Asia [2] Epidemiology - Chikungunya fever is endemic in tropical and subtropical regions, with a history of input cases in China, particularly from Southeast Asia and South Asia [3][4] - The presence of Aedes mosquitoes in southern China increases the risk of local outbreaks following imported cases [4][5] Prevention and Control - Experts suggest that controlling local transmission requires measures to reduce mosquito populations and isolate infected patients [6] - Public health recommendations emphasize the importance of eliminating standing water to prevent mosquito breeding and using effective mosquito repellent products [7]
