Then governors in the US would than have to quarantine everyone (be they at that point asymptomatic or symptomatic) that came into contact with someone like Hickox or Vinson, even if someone like Hickox or Vinson was asymptomatic, too.
No one complained. In fact, it's very rare you'll hear us saying Mayor Jackson and Governor Kasich worked together and did a good job.
So, yeah, these whiners should accept their quarantine with some dignity and class. Other people have, and it seems to have worked out just fine.
Yes, pretty much we have to do what was done back in the smallpox days. That's the point of stopping air traffic, so we don't have to get silly here because we let things get out of hand by letting these folks wander around.
When somebody got smallpox, everybody in the house was quarantined - symptoms or not.
The bit about not being infections while asymptomatic is a guess by the doctors. I doubt very much you only come infectious at the first symptom, likely it's some hours before.
Letting exposed but asymptomatic folks wander around until they vomit on the subway is not a good idea. That's why we should strive to keep the number of exposed folks in the USA to zero. How in the world are we going to help Africa if we are consumed with fighting it here?
