COVID-19 Outbreak (Update: More than 2.9M cases and 132,313 deaths in US)

Sure, but the Flu doesn't destroy the small airways and lead to a potentially long term 25% reduction in lung capacity, right? I mean, we don't even know if that is permanent or can be treated or am I missing something?

Does this happen regularly to people who have had COVID-19? Or is this a rare outlier?
