流感和普通感冒有何区别？如何预防流感？一文了解

Core Viewpoint - The article emphasizes the significance of understanding influenza, its symptoms, transmission methods, and preventive measures, especially during the winter season when flu cases rise [1][3][8]. Group 1: Differences Between Influenza and Common Cold - Influenza is caused by the influenza virus, while the common cold can be caused by various viruses such as rhinoviruses and coronaviruses [5]. - Symptoms of influenza appear suddenly and are more severe, including high fever (above 38°C) lasting 3 to 5 days, while common cold symptoms develop gradually and usually involve low fever or no fever [6]. - Influenza can lead to serious complications like pneumonia and myocarditis, whereas the common cold has a low risk of complications [6][10]. Group 2: Transmission Methods - Influenza spreads primarily through respiratory droplets when an infected person coughs, sneezes, or talks [3]. - Contact transmission occurs when the virus is transferred from contaminated surfaces to hands and then to the face [3]. - Aerosol transmission can happen in poorly ventilated spaces, increasing the risk of infection [3]. Group 3: Prevention Strategies - Annual vaccination is the most effective way to prevent influenza, recommended for children over 6 months old [8]. - Good personal hygiene practices, such as frequent handwashing and using masks in crowded places, are crucial for prevention [8][9]. - Maintaining a well-ventilated environment and enhancing personal immunity through a balanced diet and regular exercise are also important [8]. Group 4: Management of Influenza Symptoms - Individuals showing symptoms like fever and cough should rest and seek medical attention promptly [10]. - For children, it is advised to wait until they are symptom-free for 48 hours after fever resolution before returning to school to prevent virus transmission [10].
