A lot of the asymptomatic cases had pneumonia in their lungs too. They were however still able to expel CO2 and so did’t feel shortness of breath.

- pbhjpbhj 7y agoI've heard this more recently that it's a characteristic which means that people who think they're getting better will then suddenly have a turn for the worse, because they don't feel as sick but their blood oxygen level is actually quite low -- they try to exert themselves, go upstairs say, and then faint. Happened that way to a close friend of mine.
