Core Viewpoint - The article emphasizes the importance of mosquito control to prevent the spread of Chikungunya virus in Foshan, as the city has initiated a Level III public health emergency response due to the outbreak [2]. Prevention Measures - Mosquito control is crucial for preventing Chikungunya, which is transmitted by Aedes mosquitoes and characterized by fever, joint pain, and rashes [3]. - Outdoor activities should be conducted with precautions, such as wearing light-colored long-sleeved clothing to minimize skin exposure, especially during peak mosquito activity times like early morning and evening [4]. - Effective mosquito repellents should be applied to exposed skin and clothing, with regular reapplication as per instructions. Homes should be equipped with screens on doors and windows, and mosquito nets should be used while sleeping [5]. - Avoid spending extended periods near mosquito breeding grounds, such as shaded areas, grass, bamboo groves, and stagnant water [6]. - Regularly eliminate standing water around homes to disrupt the mosquito life cycle [8]. - Empty, invert, or properly cover containers that can collect water, such as pots, buckets, and tires [9]. - Clear clogged drainage systems and ensure water flows freely to prevent stagnant water accumulation [10]. - Change water in indoor plants every three days and clean the containers to prevent mosquito breeding [11]. - Water storage containers must be tightly covered or treated with safe mosquito larvicides [12]. - Properly dispose of garbage, especially items that can collect water, to prevent them from becoming breeding sites [13]. - Community participation in health campaigns and mosquito control efforts is encouraged to create a mosquito-free environment [14]. - Individuals experiencing symptoms like fever, joint pain, or rashes should seek medical attention promptly and inform healthcare providers of their travel and mosquito exposure history [15].

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]
