This may be a stupid question but Google gives me nothing and it's a wonder of mine.
If covid (a respiratory virus) stops affecting people with the lungs , so no cough or shortness of breath etc.
What is sending people into hospital? I know there is the rare side effects of it like blood clots.
But in a general speaking way, covid has always been a cough, even in vaccinated it's affected breathing , even if it's not been too serious. But this new variant isn't causing a cough and the other symptoms are mild.
So what is the symptom that leads to hospitalisation now?
