[Diagnostic protocol for febrile lung infiltrates during the COVID-19 pandemic]. / Protocolo diagnóstico de los infiltrados pulmonares febriles durante la pandemia de la COVID-19.

Chest x-ray and computed tomography (CT) scans are important pillars for the diagnosis of lung involvement in COVID-19. The radiological image is typically characterized by peripheral, bilateral ground glass opacities (GGO), mainly located in the lower lobes. The limited sensitivity and specificity of these imaging techniques and possible atypical morphological or topographical presentations make it necessary to always rule out other infectious and non-infectious diseases. Therefore, it is fundamental to consider the patient's clinical and analytical data and the epidemiological circumstances.
