Prove it? Do you have access to these hospitals personally? How can you account for specifically how many have died? Do you have records you can show us because as far as I know NONE of this is public information. If you work in a hospital or medical setting and you're providing this information you're breaking patient confidentiality for a start. How is a virus that has already been proven to affect 0.1-0.4% (this itself VISIBLY available on any coronavirus stats page) of the population severely somehow equating to 'full hospitals and morgues with people dying or dead from this virus'?
I took a walk through a Los Angeles area hospital when Los Angeles was the epicenter of the crisis a few months ago. It was packed, patients gasping for air on gurneys in the halls due to lack of space. Had a few nightmares of it since visiting. The median age of patients was younger than i had anticipated.
