The rational voices seem to be coming from those who have important jobs that would have to be done anyway or those who wouldn't be paid for time off. However, there seems to be a large contingent desperate to stir this up enough so the government is forced to close schools etc and give everyone a nice holiday. Which may be good for some but will be a disaster for others.
My personal opinion is that schools will close, probably for a few days before the Easter holidays to try and get the message across that travel should be restricted during the holidays but it's far too early to impose those restrictions now, as by the time it really matters, people will have had enough and be breaking whatever rules are in place.
