Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been associated with prolonged post-acute symptoms in at least 10% of patients [1, 2]. The majority of published data evaluates hospitalised patients with severe SARS-CoV-2 disease (COVID-19) with symptoms and pulmonary function defects several months after discharge [1]. Most of the infected subjects develop mild symptoms and are treated as outpatients. Though they are also reported to suffer from prolonged symptoms, their lung function is studied far less. Furthermore, the prolonged symptoms and objectively measurable findings are usually not compared to a group suffering from airway infection caused by other pathogens [2]. As spirometry and other aerosol-producing procedures are minimised during the pandemic, there are no reports on lung function during acute COVID-19.

严重急性呼吸综合征冠状病毒 2 (SARS-CoV-2) 与至少 10% 的患者的急性后症状延长有关 [1, 2]。大多数已发表的数据评估了出院数月后出现症状和肺功能缺陷的严重 SARS-CoV-2 疾病 (COVID-19) 住院患者 [1]。大多数受感染的受试者会出现轻微症状，并被视为门诊病人。尽管据报道他们也患有长期症状，但对其肺功能的研究却少得多。此外，长期症状和客观可测量的发现通常无法与患有其他病原体引起的气道感染的人群进行比较[2]。由于肺活量测定和其他产生气溶胶的程序在大流行期间被最小化，因此没有关于急性 COVID-19 期间肺功能的报告。
