| 1 | Persisting lung pathogenesis and minimum residual virus in hamster after acute COVID-19显示文摘Dear Editor,Severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)has infected more than 200 million people,causing coronavirus disease 2019(COVID-19)worldwide.Lungs are the primary target organ of SARS-CoV-2 infection.The mild COVID-19 cases develop symptoms of fever,fatigue,muscle weakness,chest pain,headache and cough(Chen et al.,2020;Wang et al.,2020;Zhu et al.,2020),while severe COIVD-19 cases might have pneumonia,breathing difficulties,multiple organ failure and death(Chen et al.,2020;Wang et al.,2020;Zhu et al.,2020).Both the clinicians and researchers have largely focused on the acute phase of COVID-19,but the long-term health consequences of the COVID-19 patients after clinical recovery remain less investigated.Several clinical cohorts demonstrated that some patients discharged from hospital still experience symptoms including fatigue,muscle weakness,chest pain,cough and breathing difficulties(Carfi et al.,2020;Lim et al.,2020;Huang et al.,2021).Moreover,severely impaired pulmonary diffusion capacities and abnormal chest imaging manifestations were observed in some convalescent patients(Huang et al.,2021).Surprisingly,residual virus(An et al.,2020;Yao et al.,2020;Kim et al.,2021)were detected in some convalescent patients. | Lunzhi Yuan Huachen Zhu Ming Zhou Jian Ma Rirong Chen Liuqin Yu Wenjia Chen Wenshan Hong Jia Wang Yao Chen Kun Wu Wangheng Hou Yali Zhang Shengxiang Ge Yixin Chen Quan Yuan Qiyi Tang Tong Cheng Yi Guan Ningshao Xia | 2022 | Protein & Cell2022,13,1: | 1 |
