Citation required (I've looked, and all I can find are annual mortality rates per capita, which are higher, certainly, but not double the rate for a year). Even if you're right, a doubling of baseline mortality per day is certainly something plausible for influenza in specific scenarios. Italy as a whole is now seeing new cases per day roughly twice that observed in the spring, and yet deaths are up a tiny fraction of what you would expect from the Lombardy example. So it's not clear that Lombardy represents a typical outcome, even for Italy: http://opendatadpc.maps.arcgis.com/apps/opsdashboard/index.h... Point being, again, it's difficult to draw conclusions from data points that are on the extremes of the distribution. The IFR is a measurement of average behavior. |

Testing was awful in the spring, serological surveys were made in June and estimated that only 15% roughly of the cases were caught and other surveys estimated even lower percentages (as low as 6%). The territorial distribution is also much more even this time, so it is easier to cope for the healthcare system.
My point is that any a priori estimate of the IFR falls apart if the healthcare system fails and the purpose of lockdown is to avoid that. You don't lock down because it's the only way to keep the IFR down; you lock down when you realize that tracing is failing to capture and/or isolate many cases, and therefore lockdown is the only remaining way to keep the IFR down.
