Abstract

In conclusion, the two aforementioned studies underline the critical importance of the population being examined. It is key that BAL and less invasive methods be compared prospectively in a cohort of consecutive patients with suspected SARS-Cov-2 infection who have been enrolled based on criteria decided beforehand, preferably across a wide spectrum of disease severity. This would allow us to decide reliably when it is clinically useful to perform an invasive procedure that, in this specific setting, implies organizational complexity and risks to the health-care staff.
