The Wise One flagged this up and she doesn't read the sensationalist press. But at the end of the day it seems a good idea. Better than leaving the decision to a numbskull like Boris, who took measures very belatedly and then proceeded to infect all the nursing homes. If you think about it, most countries had a blacklist of countries they wouldn't accept travellers or flights from. Some countries closed their borders altogether. What other sanctions would the WHO have against those countries who don't comply. All a bit more of the same, really. Let's hope it's never necessary.
