A 62-yr-old male with confirmed COVID-19 required endotracheal intubation and invasive mechanical ventilation. The chest computed tomography scan suggested that, compared with that before intubation (A), the pulmonary disease had progressed 3 days after intubation (B). This progression was more likely related to the disease itself as there were no signs of ventilator-associated lung injury. (Photographs by Dr. Haibo Qiu.)
