At times of national crisis of course we look to our gov for direction.
They have the birds over view of what's going on. Medical experts, business /commerce /education / and so on will all be Chipping in.
However, we on the ground also have to trust our instincts and further distill gov information.
I'd happily start self isolation now with my dc, but I'm concerned about punitive fines and loosing my job.
As time goes on I have to balance that fear with the risk of myself and dc falling ill.
I strongly feel the gov should be supporting those who want to pull their dc, or work from home etc.
I have colleagues whose dc are going on a planned trip to northern Italy?
It may even be slightly over the border into France I'm not sure. Another co worker has elderly neighbours just returned from Italy skiing.
Etc etc. The office windows are tightly shut, and everyone every laissez faire about it.
