The countries with control over the spread are: China, South Korea, Japan, Singapore, best for us if we move there.
The virus is spreading WITHIN each country as well as crossing borders. Effective control measures are required within each country.
Those people on the cruise ship weren't 'quarantined'; healthy people were kept in close proximity to the virus with no effective controls. That's why so many of them got sick.
It's here now, lets deal with it and leave the 'he who smelt it dealt it' to the WHO report in 2021/2

How was your plan of closing the border BEFORE they know they've got a novel virus that spreads asymptomatically going to get triggered?
