Ah, that makes more sense, although it is basically infect your neighbours, don't come down to Rome with your germs - and haven't travel bans been declared ineffective.
Indeed, what they mean is "containing the spread within a specific area", which doesn't help much if you're inside it.
The general medical opinion seems to be that infection rates will increase for 6-8 weeks, meaning that 'containment' within specific areas may become irrelevant, when you simply end up with adjoining containment areas with large populations.
Moving back to the pres element of our board, I wonder how various broadcast media can cope with a 'mass isolation' situation where minimum staffing levels are required to provide a service if many of the technicians and talent are stuck at home for 2-3 weeks.
Without wishing to appear to dismiss the potential seriousness of the situation, are we likely to end up with
"News at Ten, with Huw from his Sofa"
"Sophy Ridge on Sunday, from her conservatory"?
I am sure it could be done, although the techs would still need to be in place to make it all happen.
