国家疾控局提示当前流感总体处于中流行水平

Core Viewpoint - The article highlights the rising trend of acute respiratory infectious diseases in China, including influenza, respiratory syncytial virus, and rhinovirus infections, indicating the onset of the respiratory infectious disease epidemic season. Experts recommend timely vaccination against influenza and other related viruses [1]. Group 1: Current Situation - The overall influenza activity in China is at a moderate epidemic level, currently in an upward phase, with southern provinces experiencing higher activity than northern ones [1]. - The H3N2 subtype of the influenza virus accounts for over 95% of the cases, with a small number of H1N1 and B-type influenza viruses circulating concurrently [1]. Group 2: Pathogens and Vaccination - The main pathogens causing acute respiratory infections at this stage are known common pathogens, with no new or unknown pathogens detected [1]. - Due to the variability of the influenza virus, the components of the influenza vaccine are adjusted and updated annually, and immunity has a time-limited effectiveness. Therefore, it is recommended to get vaccinated before the peak of the local influenza season [1]. - Vaccination is beneficial and recommended at any time during the influenza season, even if it is not done before the peak [1].
