中疾控：今年存在甲流乙流共同流行

Group 1 - The current influenza activity in China has entered a rapid rising phase, with most provinces reaching moderate epidemic levels and some provinces even reaching high epidemic levels [1][2] - The predominant strain for the 2025-2026 flu season is the H3N2 subtype, differing from the previous season which was dominated by the H1N1 subtype. There is also co-circulation of H1N1 and B type influenza viruses [2] - There has been a significant increase in reported outbreaks of influenza in childcare institutions and schools, with a notably higher positive rate of influenza virus detection in the 5-14 age group compared to other age groups [2] Group 2 - It is crucial to differentiate between common colds and influenza, as influenza typically presents with more severe systemic symptoms such as fever and muscle aches, while common colds are characterized by milder symptoms [3] - Rapid testing methods for influenza are available, allowing for diagnosis within half an hour, and early antiviral treatment is highly effective [3][4] - High-risk groups, including infants, the elderly, pregnant women, and those with chronic conditions, should seek medical attention promptly if diagnosed with influenza to prevent severe complications [4]
