Group 1 - The French Public Health Agency reported 30 local transmission cases of Chikungunya fever from May 1 to August 26 this year, totaling 228 reported cases [1] - The cases are primarily concentrated in the southern regions of France, including Provence-Alpes-Côte d'Azur, Corsica, and Occitanie [1] - The increase in Chikungunya transmission is linked to a virus strain highly adapted to the Aedes albopictus mosquito, prevalent in the Indian Ocean territories, particularly Réunion Island [1] Group 2 - During the same period, the health department recorded 946 cases of imported Chikungunya, 825 cases of dengue fever, and 7 cases of Zika virus disease in France [1] - According to the World Health Organization, Chikungunya is mainly transmitted by Aedes aegypti and Aedes albopictus mosquitoes, with symptoms including fever, joint pain, muscle pain, headache, and rash [1] - Most patients recover within a week, although joint pain may persist for a longer duration [1]

Core Viewpoint - The article addresses the recent emergence of mosquito-borne diseases in southern cities of China, particularly focusing on the prevention and control measures recommended by the National Center for Disease Control and Prevention [1] Group 1: Understanding Mosquito-Borne Diseases - Mosquito-borne diseases are defined as illnesses transmitted through mosquito bites, with dengue fever, chikungunya, and Zika virus being the three common viral diseases globally [2] - These diseases are primarily spread by Aedes aegypti and Aedes albopictus mosquitoes and are not transmitted through casual contact or respiratory routes [3] Group 2: Treatment and Vaccination - Currently, there are no vaccines or specific medications available for these three diseases in China, and treatment mainly involves supportive care and mosquito isolation [4] - For chikungunya, rest, fluid intake, and over-the-counter pain relievers like acetaminophen can alleviate symptoms, while aspirin and other non-steroidal anti-inflammatory drugs should be avoided until dengue fever is ruled out [4] Group 3: Personal Prevention Measures - Individuals are advised to create a "mosquito-free space" by wearing light-colored long-sleeve clothing and using mosquito repellent containing DEET or other active ingredients during outdoor activities [5] - Accommodation should be chosen with mosquito-proof measures, and symptoms like fever or joint pain should prompt immediate medical consultation [5] Group 4: Travel Precautions - Travelers are encouraged to research mosquito-borne disease risks at their destinations and prepare adequate protective supplies, including mosquito repellent and light clothing [6][8] - Post-travel, individuals should continue to monitor their health for two weeks and seek medical attention if symptoms arise [9] Group 5: Community Cooperation in Epidemic Situations - The public is urged to assist in community efforts to eliminate mosquito breeding sites by cleaning up stagnant water and maintaining hygiene [10] - Emphasis is placed on the importance of cutting the "human-mosquito-human" transmission chain, especially during the active summer mosquito season [11]

Core Viewpoint - Chikungunya fever is preventable, treatable, and controllable, and there is no need for panic; the key is to eliminate standing water, control mosquito populations, and prevent bites [1] Group 1: Disease Overview - Chikungunya fever is an acute mosquito-borne infectious disease caused by the chikungunya virus, primarily prevalent in Southeast Asia, South Asia, and Africa, transmitted by Aedes mosquitoes [2] - The Aedes aegypti mosquito is active during the day and can survive drought for months, making it an effective vector for human diseases [2] - The chikungunya virus has been reported in over 100 countries across Africa, the Americas, Asia, Europe, and islands in the Indian and Pacific Oceans [2] Group 2: Symptoms and Treatment - Symptoms of chikungunya infection include sudden high fever (over 39°C), symmetrical polyarthralgia, and rash, with mild cases being predominant [4] - High-risk groups, such as infants, elderly individuals over 65, and those with underlying health conditions, may experience severe symptoms [4] - There are no specific antiviral drugs for chikungunya; treatment is primarily supportive, including rest, hydration, and pain relief [4] Group 3: Prevention Measures - To prevent chikungunya, it is essential to avoid mosquito bites by eliminating breeding sites and using biological, physical, and chemical methods to control mosquito populations [7] - Recommendations for outdoor activities include wearing light-colored long sleeves and pants, using mosquito repellent, and avoiding prolonged stays in shaded or grassy areas [5] - After traveling to areas with a risk of infection, individuals should monitor their health for two weeks and seek medical attention if symptoms arise [5]
