I wonder if they started to examine young kids and babies more because to my knowledge there are hardly any kids under 10 years who got infected by now.
which is odd since i.e. "common" influenza viruses severly attack younger folks (and older ones) as their immune system isn't that potent.
There must be reason for that.
All Italy should get a lockdown to actually reduce the spread, since the virus has certainly already spread all over the country at this point. We aren't anticiping the corona behavior enough.
I (from austria) regulary travel to italy and back and your idea is not manageable. Italy is a huge country with 60 million citizens, a HUGE coastline with hundrets of ports and it's one of the biggest economic powers in the EU with massive daily tradings with it's neighbours (austria, switzerland etc).
A complete lockdown would bankrupt italy within weeks and drag it's trading partners into hell too.
You can't just close the borders. Tenthousands of trucks would be stuck immediatly.
Not to talk about the hundrets of "unofficial" border crossings throughout the country. You just can't check and control them all. Since borders are officialy gone in the EU it's even harder to manage.
