The COVID-19 pandemic has created diagnostic difficulties with the increase in mental health illnesses that often present with nonspecific symptoms, like hypersensitivity pneumonitis. Hypersensitivity pneumonitis is a complex syndrome of varying triggers, onset, severity, and clinical manifestations that can be challenging to diagnose in many cases. Typical symptoms are nonspecific and can be attributed to other entities. There are no pediatric guidelines, which contributes to diagnostic difficulties and delays in treatment. It is particularly important to avoid diagnostic biases, have an index of suspicion for hypersensitivity pneumonitis, and to develop pediatric guidelines as outcomes are excellent when diagnosed and treated promptly. This article discusses hypersensitivity pneumonitis with a focus on the causes, pathogenesis, diagnostic approach, outcomes, and prognosis while using a case to illustrate the diagnostic difficulties worsened by the COVID-19 pandemic.

随着精神健康疾病的增加，COVID-19 大流行造成了诊断困难，这些疾病通常表现为非特异性症状，例如过敏性肺炎。过敏性肺炎是一种复杂的综合征，其触发因素、发病情况、严重程度和临床表现各不相同，在许多情况下诊断起来很困难。典型症状是非特异性的，可以归因于其他实体。没有儿科指南，这导致诊断困难和治疗延误。避免诊断偏差、对过敏性肺炎有怀疑并制定儿科指南尤为重要，因为及时诊断和治疗的结果非常好。本文讨论过敏性肺炎，重点讨论过敏性肺炎的病因、发病机制、诊断方法、结果和预后，并以病例说明因COVID-19大流行而加剧的诊断困难。
