市疾控主任：“十五五”期间提升疾控体系整体效能

Core Viewpoint - During the "14th Five-Year Plan" period, Beijing's disease control system will enhance various infectious disease monitoring and early warning systems, focusing on vector-borne diseases and improving response capabilities to prevent local transmission of imported infectious diseases [1][2]. Group 1: Key Initiatives in Disease Control - The Beijing CDC will optimize monitoring and early warning systems for respiratory, intestinal, and vector-borne diseases, and enhance monitoring and control of mosquito and tick-borne diseases [1]. - The establishment of the Capital Public Health Center and the promotion of coordinated governance of allergens and vector-borne diseases are highlighted as key areas of focus [1]. - The Beijing CDC aims to strengthen the overall effectiveness of the disease control system by providing ongoing guidance to district-level disease control in areas such as infectious disease and chronic disease prevention, monitoring, and emergency response [2]. Group 2: Influenza Situation and Response - Influenza activity in Beijing began to rise significantly from October last year, with the flu season starting in week 46 of 2025, four weeks earlier than the previous season [4]. - The peak positivity rate for influenza in sentinel hospitals reached 62.66%, indicating a relatively high intensity of the current flu season, although the number of visits to fever clinics was lower than in previous seasons [4][11]. - The Beijing CDC has integrated winter respiratory disease prevention into routine risk management, covering 22 key pathogens and utilizing a comprehensive monitoring network [3]. Group 3: Variants and Public Health Strategies - The main circulating strain in Beijing is the H3N2 subtype of the influenza A virus, which has undergone minor antigenic drift, potentially affecting vaccine efficacy [8]. - The CDC emphasizes the importance of different prevention strategies for various respiratory pathogens, with influenza being seasonal and manageable through vaccination and antiviral medications [10]. - The decline in patient visits despite rising positivity rates is attributed to improved public health measures and increased accessibility to medical resources, leading to a "no-symptom" approach to disease management [12]. Group 4: Vaccination Efforts - As of the 2025 flu season, 2.3346 million flu vaccines have been administered in Beijing, a 10% increase from the previous year, with coverage among key populations exceeding last year's figures [14]. - The city has provided free flu vaccinations to schoolchildren and seniors since 2007, achieving a fourfold increase in coverage compared to the self-paid period, with an average coverage rate of over 55% among schoolchildren in recent years [14]. - The Beijing CDC plans to leverage artificial intelligence for research on flu variant prediction and vaccine effectiveness in the upcoming year [15].
