Recently, Dr. Zhong Nanshan, an academician of the Chinese Academy of Engineering and a renowned respiratory disease expert, issued important guidance on influenza prevention and treatment. He specifically highlighted three scenarios in which flu patients should seek immediate medical attention: (1) persistent high fever (body temperature above 39°C lasting more than 48 hours); (2) signs of respiratory distress, such as shortness of breath, chest tightness, or cyanosis (bluish lips), indicating oxygen deficiency; and (3) significant worsening of pre-existing conditions like cardiovascular disease, diabetes, or chronic lung disorders. Dr. Zhong emphasized that influenza is not just a common cold—it is highly contagious and can progress rapidly, potentially leading to severe complications such as pneumonia, myocarditis, or even multi-organ failure, especially among high-risk groups including the elderly, children, pregnant women, and individuals with chronic illnesses. He urged the public to remain vigilant during flu season by practicing good hygiene—frequent handwashing, wearing masks, ensuring proper ventilation—and getting vaccinated annually. If infected, people should avoid self-medicating with antibiotics or antivirals and instead seek professional medical advice based on symptom severity. Recognizing warning signs early and seeking prompt care are crucial steps to reduce the risk of severe illness and protect lives.
近日，中国工程院院士、著名呼吸病学专家钟南山就流感防治提出重要建议，特别指出流感患者在出现以下三种情况时应立即就医：一是高烧持续不退（体温超过39℃且持续48小时以上）；二是出现明显呼吸困难、胸闷或嘴唇发紫等缺氧表现；三是原有基础疾病（如心脑血管病、糖尿病、慢性肺病等）明显加重。钟南山强调，流感并非普通感冒，其传染性强、进展快，尤其对老年人、儿童、孕妇及慢性病患者等高危人群可能引发严重并发症，如肺炎、心肌炎甚至多器官衰竭。他呼吁公众提高警惕，在流感高发季节注意个人防护，如勤洗手、戴口罩、保持通风，并及时接种流感疫苗。一旦感染，切勿自行滥用抗生素或抗病毒药物，而应根据病情科学判断是否需要专业医疗干预。及时识别危险信号并尽早就医，是降低重症风险、保障生命安全的关键措施。
