Summary of Key Points Core Viewpoint - The recent interview with experts from the National Center for Disease Control and Prevention (CDC) indicates that the number of new cases of Chikungunya fever in Foshan is continuously declining, and no long-term sequelae have been observed in patients [1]. Group 1: Current Situation of Chikungunya Fever in Foshan - As of August 17, Foshan reported 45 new confirmed cases of Chikungunya fever, showing a sustained downward trend from a peak of over 600 cases per day to below 100 cases [2]. - The CDC expert noted that the current cases are sporadic, and more precise control measures will be implemented to further manage the outbreak [2]. Group 2: Patient Recovery and Symptoms - The main symptoms of Chikungunya fever include fever, rash, and joint pain, with joint pain being the most concerning, particularly in small joints like the ankles [3]. - Patients typically recover within 1 to 3 weeks, and no long-term sequelae have been reported among the thousands of confirmed cases treated in Foshan [4]. Group 3: Vulnerable Populations and Immunity - Special attention is required for elderly patients with underlying conditions such as coronary heart disease, hypertension, and diabetes [5]. - Research indicates that there are at least three genotypes of the Chikungunya virus, but only one serotype, meaning that individuals develop immunity after infection and are unlikely to be reinfected [5]. Group 4: Mosquito Resistance and Control Measures - Recent studies have shown that some Aedes albopictus mosquitoes in Guangzhou carry mutations for resistance to certain pyrethroid insecticides, but this does not imply resistance to all insecticides [6]. - The CDC has confirmed that the insecticides currently in use have been evaluated for effectiveness and are deemed effective against the mosquito population [7]. Group 5: Mosquito Transmission and Lifespan - After biting an infected individual, mosquitoes can transmit the virus after an incubation period of about one week and can carry the virus until death [9]. - The environmental conditions in Guangdong are conducive to mosquito survival, with adult mosquitoes living for 1 to 2 months or longer, making mosquito control a key measure in preventing the spread of the virus [9]. Group 6: National Risk Management - The recently released "Chikungunya Fever Prevention and Control Technical Guidelines (2025 Edition)" categorizes the risk of Chikungunya fever across 31 provinces in China, with six provinces identified as high-risk areas based on mosquito activity and historical dengue fever cases [10]. - The classification of risk levels does not necessarily reflect the current outbreak status but is based on local mosquito activity and previous case reports [10].

Group 1 - The current situation of the Chikungunya fever epidemic in Foshan shows a decline from over 600 daily cases at its peak to below 100 cases, indicating the effectiveness of previous control measures [2] - The main symptoms of Chikungunya fever include fever, rash, and joint pain, with ankle joint pain being the most common.
