I’m pretty sure it would be unconstitutional to prevent us from traveling anywhere. The US could bar licensed airlines from leaving US soil and landing in some area, but that doesn’t mean we can’t find anther way in. Like flying to canada and then to cuba in the old days.
So, your are assembling a tremendous straw man, and I’m not sure why.
"The researchers are concerned that it could mutate further so that it can spread easily from person to person, and trigger a global outbreak.
While it is not an immediate problem, they say, it has “all the hallmarks” of being highly adapted to infect humans and needs close monitoring."
It could be a something or it could be a nothing. Of course keep an outlook on it. How well did WHO do with that one? By the time its known what’s happening it can be too late.
Seems the attitutde of the public (media?) has changed since the great polio epidemics. Of course, if they became politicized at the time I probably wouldn’t have noticed it, being born in 1948 and they came to and end with vaccines around 1955.
Death rates are still low. Of course, one wonders if increased death rates will increase in a delayed manner after this second wave, or if something else is at play. One article I read said that the infected are on the average much younger now, which could indicate that the death rate wont follow the increase.
