>You carry on the "draconian measures" until the virus is unable to spread and dies out. It's not magic. It spreads through human contact. Reduce contact you reduce transmission.

What does this look like in practice? Do you intend to keep every national border closed until the entire planet has eradicated the disease? How long do you expect that to take? Do you believe this is sustainable for 5 years? What about 20 years? Will you also be keeping the schools closed during this time?

I think there are some countries that have no more cases, so each country would have managed same thing the issue can be solved, so a solution is to isolate only the countries that have a high risk.
