That may be true, but the evidence mostly is pointing in the direction of undercounting COVID deaths. In northern Italy the official death count was less than half of "excess deaths", with the worst-hit areas having the most excess deaths. Certainly some of the excess deaths are due to people avoiding hospitals, or higher stress levels, but a lot are due to COVID deaths at home, or undiagnosed COVID deaths. Also, we still don't really understand this disease enough to know what effects it has on the body. There have been reports of people with COVID having strokes at much higher rates than would be expected for the same age demographic. It will be hard to tell which complications were coincidence and which were caused by COVID until later on when we have more data.
