Core Viewpoint - Guangzhou's disease control center has launched a new feature on its mosquito monitoring map to provide daily travel risk alerts to citizens, emphasizing the importance of personal protection against mosquito-borne diseases [1][4]. Group 1: Mosquito Monitoring Map Features - The mosquito monitoring map allows users to check low, medium, and high-risk areas for mosquito density, providing early warnings for diseases like dengue and chikungunya [2]. - The map has been operational since 2023 and can be accessed via the official website and the "Guangzhou CDC iHealth" WeChat account [2]. - The monitoring results are updated bi-weekly during low mosquito activity seasons and weekly during peak transmission periods, with the latest data showing 45 out of 120 monitored districts meeting control standards [2][4]. Group 2: Risk Assessment Metrics - The risk levels are determined using the Breteau Index (BI) and the Mosquito Ovitrap Index (MOI), with specific thresholds indicating varying levels of risk for dengue transmission [2][3]. - A BI above 5 indicates transmission risk, while a BI above 20 suggests outbreak risk; similarly, an MOI above 5 indicates transmission risk, and above 20 indicates regional epidemic risk [3]. Group 3: User Guidance and Recommendations - Users can receive alerts if they are in areas undergoing mosquito-borne disease control measures, prompting them to take precautions against mosquito bites [4]. - Recommendations for individuals in high-risk areas include eliminating standing water, using mosquito nets, and applying mosquito repellent [5].
