The government can certainly advice, for schools to be closed, for all crowded activities avoided, for companies asking people working from home if at all possible, telling people how to use what masks etc. etc.
For anybody who has the time, I strongly recommend reading this
WHO report, which is full of lessons learnt - what was done in China and why they did it is sobering - I am not optimistic this government, or most western governments, will/can mobilise people similarly to deal with the problem.
Since the government is hardly doing anything, what I think is going to happen is more people will be infected, and die, before fear gives rise to the same restrictions, whether self imposed or otherwise. With Italy, we have a live "case study" right in front of our own eyes right now. I suspect we will be just like them, it is just a matter of time.
