I'd say the virus isn't more dangerous than the flu, it's just requiring a very specific set of equipment which we didn't need as much previously.
of course that will all depend on what the number evolves to over time.
So it is plausible that Italy (and other countries) problems are a result of a double whammy of flu and Covid19 as it is due to the severity of Covid19 itself.
They basically turned hospitals into covid19 infection parties.
All year round is basically influenza infection party everywhere yet it doesn't overwhelm our medical systems.

In the North (and particularly in Lombardy) the situation is dramatic, in the center and in the south it is not (yet) that bad.
Basically the lock-down (started on national level on the 10 th of March) seemingly - and for the moment - managed to work to reduce the spread of the infection in other regions.
The previous lock-down (limited to some cities/provinces of the north) was only a couple days before and evidently too late to be effective.
