近日，中国疾病预防控制中心（中疾控）发布最新监测数据显示，全国范围内流感病毒阳性率呈现明显下降趋势。这一变化表明当前流感疫情已进入回落阶段，公众感染风险逐步降低。根据中疾控每周发布的流感监测周报，自2024年冬季流感高发期以来，流感样病例就诊比例和病毒检测阳性率在1月中下旬达到峰值后持续走低。截至最新统计周期，多地流感病毒核酸检测阳性率已降至10%以下，部分南方省份甚至低于5%。专家分析认为，随着气温回升、人群免疫屏障增强以及防控措施的有效落实，流感传播动力显著减弱。尽管阳性率下降，中疾控仍提醒公众不可掉以轻心。春季仍是呼吸道传染病高发季节，建议继续做好个人防护，如勤洗手、戴口罩、保持室内通风，并鼓励尚未接种流感疫苗的高危人群及时补种。此外，若出现发热、咳嗽等流感样症状，应及时就医并避免带病上学或上班，以减少传播风险。总体来看，当前流感疫情趋于平稳，但常态化防控仍需坚持，以保障公众健康和社会正常运转。
Recently, the Chinese Center for Disease Control and Prevention (China CDC) released updated surveillance data showing a clear downward trend in influenza virus positivity rates nationwide. This indicates that the current flu season is entering a declining phase, with the public’s risk of infection gradually decreasing.According to China CDC’s weekly influenza surveillance reports, both the proportion of patients presenting with influenza-like illness and the positivity rate of virus testing peaked in mid-to-late January 2024 during the winter flu surge and have since steadily declined. As of the latest reporting period, influenza virus nucleic acid test positivity rates have dropped below 10% in many regions, and even below 5% in some southern provinces. Experts attribute this decline to rising temperatures, strengthened population immunity, and effective public health interventions, all of which have significantly reduced transmission dynamics.Despite the falling positivity rates, China CDC cautions the public against complacency. Spring remains a high-risk season for respiratory infections. Continued personal protective measures—such as frequent handwashing, wearing masks when necessary, ensuring good indoor ventilation—are still recommended. High-risk individuals who have not yet received the seasonal flu vaccine are encouraged to get vaccinated promptly. Additionally, anyone experiencing flu-like symptoms such as fever or cough should seek medical care early and avoid attending school or work while ill to minimize further spread.Overall, the flu situation is stabilizing, but sustained routine prevention efforts remain essential to protect public health and maintain normal social operations.
