Hypersensitivity pneumonitis (HP), also known as extrinsic allergic alveolitis, is an immunologically mediated disorder that typically presents as a case of interstitial lung disease (ILD) in response to any identified or unidentified antigen. We present a case of a 46-year-old female with HP, who presented with fever and shortness of breath. Although negative by real-time reverse transcription-polymerase chain reaction (RT-PCR), her condition was initially diagnosed as COVID-19 clinically as a result of anchoring bias due to similar symptoms and radiologic features presenting in the pandemic. A detailed further probing into history revealed the diagnosis of HP due to cat hair, and hence, was managed accordingly.
过敏性肺炎（HP），也称为外源性过敏性肺泡炎，是一种免疫介导的疾病，通常表现为间质性肺疾病（ILD），由任何已识别或未识别的抗原引起。我们报告一例46岁患有HP的女性病例，她表现出发热和呼吸急促。尽管实时逆转录聚合酶链反应（RT-PCR）结果为阴性，但由于大流行期间出现的类似症状和放射学特征导致的锚定偏差，她的病情最初在临床上被诊断为COVID-19。进一步详细询问病史后发现是由于猫毛引起的HP，因此进行了相应的治疗。
