Yet it is the only way. Nobody wanted to do this to our economy yet it was necessary, both the gov and the opposition agreed on that because all the doctors said we must do it unless we want to see hospitals collapse under numbers they can not face.
About 10% of the cases need intensive care aka machines to support their vital functions for a period yet with the level of contagion we have now the structures in Lombardy, the region with one of the best health care systems, working even above their capacity and barely keeping up with the people who needs to be cured. If this spreads any further be it in Lombardy or other regions of Italy with a worse and or less structures the doctors will have to choose who they have to save. So this total blockade.
Also this is the method used in China and now, it seems, the situation in Wuhan is almost under control. We have to make this heavy sacrifices now that it can still somewhat be contained, or at least I hope so, to come out from this crisis earlier and better.
