Dr. Ioannidis: This is still a major challenge. COVID-19 has become a notifiable disease so it is readily recorded in death certificates. What we do know, however, is that the vast majority of people who die with a COVID-19 label have at least one and typically many other comorbidities. This means that often they have other reasons that would lead them to death. The relative contribution of COVID-19 needs very careful audit and evaluation of medical records.

 In terms of numbers of lives lost, so far the COVID-19 impact is about 1% of the 1918 influenza. In terms of quality-adjusted person-years lost, the impact of COVID-19 is about 0.1% of 1918 influenza, since the 1918 influenza killed mostly young healthy people (average age 28), while the average age of death with COVID-19 is 80 years, with several comorbidities.

...

The predictions of most mathematical models in terms of how many beds and how many ICU beds would be required were astronomically wrong. Indeed, the health system was not overrun in any location in the USA, although several hospitals were stressed. Conversely, the health care system was severely damaged in many places because of the measures taken.
