Fubho, There are over a dozen of these studies now. You should start googling them rather than speaking out of ignorance. The first link you posted wasn't even a scientific study. Instead, it's quoting a phlebotomy technician who is reporting an observation, but there is no link to confirm the results she saw.
Moreover, I looked around for the details of the test made by Abbott, specifically for whether they also test for antibodies, but I couldn't find any. What I could conclude, however, is that Abbott's test was made for speed, so it's hard to know whether they also test for people who currently test negative for COVID-19 but may have had it in the past. Such data should be shared by Abbott, not some low-level technician.
The second link you posted isn't a scientific study, either. It's just a report on a government estimate, and it cites "studies done in Germany and Iceland" but doesn't provide any links or details.
Either way, we can already confirm that COVID-19 is more contagious than seasonal flu, and it's causing a surge in hospitalizations all around the world. To conclude that the death rate from COVID-19 is a lot lower than the numbers suggest means you'd have to assume that COVID-19 is ten times more contagious than previously thought, which is a fantastic claim given that it's already proven to be pretty damned contagious.
