Core Viewpoint - The recent emergence of the H3N2 influenza virus has led to increased public concern, with symptoms reported to be more severe than those of a common cold, as indicated by the China CDC's report showing over 90% of positive samples being H3N2 [1] Group 1: Differentiating Between Common Cold and Influenza - Influenza symptoms typically appear suddenly, including high fever, headache, sore throat, cough, significant fatigue, and muscle aches, while common cold symptoms develop more gradually and are generally milder [2] - High fever (above 39°C) lasting 3-5 days is common in influenza, whereas common cold fever is usually below 38°C and resolves within 1-2 days [2] - Early identification of symptoms is crucial for appropriate treatment and resource management [2] Group 2: Recovery Timeline and Potential Aftereffects - Antiviral treatment is most effective when administered within 48 hours of symptom onset, with medications like Oseltamivir and Marbofloxacin recommended [3] - Influenza itself does not typically leave aftereffects, but delayed treatment can lead to serious complications such as pneumonia or myocarditis, which may have long-term health impacts [3] - Healthy adults usually recover from typical influenza symptoms within a week, but some may experience lingering cough and fatigue for up to two weeks [3] Group 3: Preventive Measures for H3N2 Influenza - Vaccination is strongly recommended as the most effective and economical preventive measure against influenza [4][5] - The composition of the flu vaccine is adjusted annually to match circulating strains, enhancing its effectiveness [5] - Public health recommendations include wearing masks in high-risk areas and isolating when symptomatic to prevent the spread of the virus [5]
