Every study or op-ed I see seems to be focusing on uncounted Covid-19 cases.

You even have insane tier ones like that WSJ op-ed that claims millions of Americans already have it.

The problem is clear. Bad cases are more likely to be tested. Aside from first responders, and travelers, there isn't a ton of testing of asymptomatic people so we don't know how many cases are like that, and that skews mortality rates.

But how many uncounted deaths could their be? Everyone is on lock down. They just found a bunch of dead people in a retirement home in Spain. People could be dead in their houses right now, right?
