p16: "In the most effective mitigation strategy examined, which leads to a single, relatively short epidemic (case isolation, household quarantine and social distancing of the elderly), the surge limits for both general ward and ICU beds would be exceeded by at least 8-fold under the more optimistic scenario for critical care requirements that we examined. In addition, even if all patients were able to be treated, we predict there would still be in the order of 250,000 deaths in GB, and 1.1-1.2 million in the US."
EDIT to rrss's comment:
First, note that ~60k is how many people died and tested positive AND were coded as COVID-19. It's not necessairly how many people died because of a COVID-19 infection. We will not know the real #'s until all-cause death is examined. There appears to be a significant drop in "normal" pneumonia deaths for example. It also ignores the error bars on the testing false/positive/negative rates.
Second, I'll restate: The US beat every single explicitly enumerated via a integer expert pre-peak total deaths prediction; by a lot.
If the authors had given a table for the US, we could see what their model predicted, but they did not, and _you_ assuming that the US is a linear relation to GB may or may not be accurate.
