Core Viewpoint - The emergence of local outbreaks of Chikungunya fever in certain regions of China has prompted a rapid response from health authorities, emphasizing the importance of mosquito control and public awareness to prevent further spread [2][5]. Group 1: Disease Overview - Chikungunya fever is an acute mosquito-borne viral infection primarily transmitted by Aedes mosquitoes, particularly Aedes aegypti and Aedes albopictus [3]. - Symptoms typically appear 3 to 7 days after infection, with common signs including high fever and joint pain, especially in small joints like wrists and ankles [3]. - Most patients recover within a week, but approximately 30% to 40% may experience prolonged joint pain [3]. Group 2: Prevention Measures - Key prevention strategies include eliminating adult mosquitoes, removing breeding sites, and avoiding mosquito bites [4]. - Personal protective measures involve wearing light-colored, long-sleeved clothing and using effective mosquito repellent on exposed skin [4]. - Environmental management includes regular cleaning of potential water accumulation sites and using approved insecticides indoors [4]. Group 3: Travel Advisory - Travelers should check for Chikungunya fever outbreaks at their destinations and take appropriate precautions [5]. - Post-travel self-monitoring for symptoms such as fever and joint pain is advised, with immediate medical consultation recommended if symptoms arise within two weeks [5].

Core Viewpoint - The increasing public awareness of mosquito prevention is driving the growth of related products and services in the market [3][5]. Group 1: Market Demand and Trends - The demand for mosquito repellent products has surged due to rising temperatures and increased rainfall, leading to a higher incidence of mosquito-borne diseases [3][4]. - In Guangdong, from July 27 to August 2, there were 2,892 new reported cases of local transmission of Chikungunya fever, prompting local governments to initiate mosquito control measures [4]. - Sales of mosquito repellent products in supermarkets have doubled in recent weeks, with overall sales up by 30% compared to July [7][5]. Group 2: Product Development and Consumer Behavior - Consumers are increasingly purchasing mosquito repellent products from supermarkets, with products prominently displayed and marketed with various features such as "baby-friendly" and "outdoor use" [6][7]. - The market for mosquito repellent products is still dominated by traditional items like floral water and incense, with a lack of innovation appealing to younger consumers [8][6]. Group 3: Biological Control Measures - Several cities in South China are experimenting with biological control methods to reduce the transmission of mosquito-borne viruses, including the introduction of non-biting mosquito species and fish that consume mosquito larvae [12][13]. - The "mosquito factory" model, which involves releasing infected male mosquitoes to suppress the population of disease-carrying females, has shown promising results in international contexts [13][14]. Group 4: Recommendations for Public Health - Public health departments are encouraged to adopt proactive measures for mosquito control, including regular supply of necessary products and public awareness campaigns [17][12]. - The cost of implementing biological control measures is estimated to be between 2 to 3 yuan per square meter, with potential for cost reduction as the scale of the project increases [14][16].
