Maybe we need to consider a more nuanced view? Maybe restrictions on their movements, to protect the public, but not a total quarantine? Maybe easier restrictions for US medical personnel, who are educated in thsi particular area and presumably don’t want to infect their family and friends, much less their fellow-citizens, and tougher restrictions on those who are not medical personnel, who may have helped a pregnant woman thinking her illness was pregnancy-related, that sort of thing.
The reality is that Ebola seems to be more and more contagious as it progresses. So a person taking care if very ill and dying people are more likely to get it than those who have little exposure and that more likely at the beginning of the illness.
And the other question is, where will we put all these people? 150 to 200 I have heard come int the US each day. That’s a lot of people to quarantine!
