Normally, if be tempted to say "not many, probably" but The median fatal case in Italy is an 81-year old with 2 comorbidities (typically two of: heart disease, COPD, diabetes, obesity). An 81-year-old has a ~10% chance of dying in any given year, and an 81-year-old with serious underlying medical conditions is even likelier to die. If you're an 81-year-old with serious underlying health issues, you have a material chance of death generally in a 2-month period (which the coronavirus has been there). On top of that, for those folks, every illness is a high-risk occurrence (even a simple cold). The situation in Italy now is bad enough that there are definitely many COVID deaths that wouldn't have happened without COVID. But it is almost certainly the case that a meaningful number of these patients would have died in those two months anyway. (Roughly 2% of all 80+ population would have died in that time if the virus didn't exist; it seems very likely that that 2% would be disproportionately inclusive of those with serious underlying health issues -- which are the people most killed with COVID.
