"The US government
is not even trying to prevent the spread of Ebola to the US."
Not quite. Yesterday the CDC announced that five major international airports in the US will be using thermometers to check all passengers inbound from the hot zone, and asking them to self-monitor for a month afterwards in any case.
Not a quarantine but a slow first step probably intended to not cause panic, which would be a bigger problem than an epidemic.
Among the odd tidbits that contradict "only from direct contact" are an advisory the ebola can survive for at least six hours outside the body. You spit on the sidewalk, four hours later someone walks in it, now they've got viable ebola in their shoes. And if has been confirmed that you can get ebola from handling the dead, who by definition are already dead, so the virus is obviously surviving "outside" of a live host.
I'm not sure where the fog
of a sneeze becomes radically different from some spittle or a glob or spit but it would seem the "aerosol" question is just a matter of degree. And two? weeks ago, it was announced that even in a cured or recovered victim, the virus was alive and well in the survivor's semen for at least six weeks. So, cured isn't safe either.
As long as George Romero isn't filming on your street, you're probably safe. Right?
