中新健康丨我国进入呼吸道传染病流行季 专家提醒：警惕叠加感染

Core Viewpoint - The onset of early winter has led to a rise in respiratory infections, including influenza, respiratory syncytial virus (RSV), and rhinovirus, with experts warning of the risk of co-infections that could lead to severe cases [3][4]. Group 1: Current Situation - The National Center for Disease Control and Prevention (CDC) has reported an upward trend in acute respiratory infectious diseases, indicating that the country is entering the flu season [3]. - The monitoring data shows a significant increase in influenza activity, with most provinces already in the influenza epidemic phase [3]. - The positivity rate for rhinovirus is notably higher in children aged 14 and under, while RSV positivity rates are fluctuating at a high level, particularly in northern provinces [3][4]. Group 2: Infection Risks - Co-infection risks are heightened during the flu season, with RSV frequently detected alongside other pathogens, such as Streptococcus pneumoniae and Hib (Haemophilus influenzae type b) [4]. - Children, especially infants under one year old, are at the highest risk for severe respiratory infections, with RSV and rhinovirus being the most common pathogens [4][5]. Group 3: Prevention Measures - Effective prevention strategies include reducing exposure to viruses during the flu season, maintaining good hand hygiene, and ensuring proper ventilation in living spaces [5][6]. - Vaccination is emphasized as a cost-effective method for preventing respiratory infections, with recommendations for continuous vaccination for children against influenza, pneumonia, and Hib [6]. - Parents are advised to seek medical attention promptly if children exhibit symptoms such as high fever, cough, or difficulty breathing [6].
