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]
