If you ask me, & some do, whether it’s wrong to get hysterical about Ebola, even though there are relatively few that are infected, being treated in the US; I’d say, it’s alright to over react. It’s what people do, rightly so, when there’s a plague. It’s a survival mechanism, to run away screaming when disease threatens life & limb.
Avoid it like the plague, is a very old cliché. It’s valid! When spewing, infected people, throwing around their bodily fluids are among the population; it really is a good idea to run the other way, yelling out warnings. I’m not sure why some think it’s best to stay calm. Not staying calm, may well save many from dying.
Someone else is now being treated for Ebola. Someone who was involved with monitoring an Ebola patient in Liberia. Someone who got on a plane with other folks & arrived back in the US.
