According to a Weibo post by Hu Yang, the deputy chief physician of the Respiratory Department of Shanghai Pulmonary Hospital, both types of viruses, H1N1 and H3N2, can cause influenza pneumonia. For patients with weakened immunity, advanced age, or severe underlying diseases, the possibility of pneumonia is even greater. Symptoms of pneumonia include persistent cough, phlegm, gradually worsening breathing difficulties, and hypoxemia. If these symptoms occur, it is necessary to go to the hospital for a chest X-ray or chest CT examination. In severe cases, ICU treatment may be required, and a small percentage of patients may need intubation treatment. Hu Yang stated that every year, there are basic patients who die from influenza virus-induced white lung, while many others recover from influenza pneumonia after treatment. However, they may be left with fibrotic lesions or even fibrosis in their lungs.
据上海市肺科医院呼吸内科副主任医师胡洋微博发文，甲流和乙流两种类型的病毒都有可能导致流感病毒肺炎。对于免疫力低下、年龄较大或有严重基础病的患者，感染肺炎的可能性更大。感染肺炎的表现为咳嗽、咳痰持续不好转，逐渐出现呼吸困难，低氧血症等。出现上述症状需前往医院检查胸部平片或者胸部CT，症状严重甚至需入住ICU治疗，少部分患者需要气管插管治疗。胡洋说，每年都有因流感病毒导致大白肺去世的基础病患者，也有不少经治疗而恢复的流感病毒肺炎患者，他们肺部通常都会留下纤维灶甚至纤维化的后遗症。
