Recently, Dr. Zhong Nanshan, an academician of the Chinese Academy of Engineering and a renowned expert in respiratory diseases, issued an important warning regarding influenza: patients should seek immediate medical attention if they experience any of the following three conditions. First, a persistent high fever lasting more than three days without improvement, especially when accompanied by chills or recurring spikes in temperature. Second, noticeable respiratory distress, chest tightness, or shortness of breath—symptoms that may indicate progression to pneumonia or other serious complications. Third, significant worsening of pre-existing chronic conditions (such as heart disease, diabetes, or chronic lung disease), or the onset of neurological symptoms like confusion, seizures, or severe headache.Dr. Zhong emphasized that influenza is not just a common cold—it is highly contagious and can progress rapidly, posing a greater threat to high-risk groups including the elderly, children, pregnant women, and individuals with underlying health conditions. He advised the public to practice good personal hygiene during flu season—such as frequent handwashing, wearing masks, and ensuring proper indoor ventilation—and to get vaccinated against influenza promptly. If infected, patients should rest adequately and stay hydrated, avoiding unnecessary antibiotic use. Should any of the above warning signs appear, immediate medical care is essential to prevent delayed treatment and potential severe outcomes.
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问题发出重要提醒：若流感患者出现以下三种情况，应立即就医。第一，持续高烧超过3天不退，尤其是体温反复升高或伴有寒战；第二，出现明显呼吸困难、胸闷、气促等呼吸道症状，提示可能已发展为肺炎或其他严重并发症；第三，原有慢性基础疾病（如心脏病、糖尿病、慢性肺病等）明显加重，或出现意识模糊、抽搐、剧烈头痛等神经系统异常表现。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威胁更大。他建议公众在流感高发季节做好个人防护，如勤洗手、戴口罩、保持室内通风，并及时接种流感疫苗。一旦感染，应充分休息、多饮水，避免盲目使用抗生素。若出现上述危险信号，务必第一时间前往医院就诊，以免延误治疗时机，造成严重后果。
