COVID-19 caused by SARS-CoV-2 may present with a wide spectrum of symptoms ranging from mild upper respiratory tract infection like illness to severe pneumonia and death. Patients may have severe hypoxaemia without proportional features of respiratory distress, also known as 'silent' or 'apathetic' hypoxia. We present a case of a 56-year-old man with COVID-19 who presented to the fever clinic of our institution with fever and cough without any respiratory distress but low oxygen saturation. The patient deteriorated over the next 2 days but eventually recovered of his illness in due course of time. This case demonstrates 'silent hypoxia' as a possible presentation in COVID-19 and emphasises the importance of meticulous clinical examination including oxygen saturation measurements in suspected or confirmed patients.
由严重急性呼吸综合征冠状病毒2（SARS-CoV-2）引起的2019冠状病毒病（COVID-19）可能表现出广泛的症状，从类似轻度上呼吸道感染的疾病到严重肺炎甚至死亡。患者可能出现严重低氧血症，却没有相应的呼吸窘迫表现，即所谓的“沉默”或“淡漠”型低氧血症。我们报告一例56岁的COVID-19男性患者，他因发热和咳嗽前往我院发热门诊就诊，当时没有任何呼吸窘迫症状，但血氧饱和度低。该患者在接下来的2天病情恶化，但最终在适当的时候康复。该病例证明了“沉默性低氧血症”是COVID-19可能出现的一种表现，并强调了对疑似或确诊患者进行细致临床检查（包括测量血氧饱和度）的重要性。
