Its being downplayed ... but the possibility exists that "Ebola Mary's" are out there. These would be people who actively carry ebola, but show no symptoms of the disease. Just like "Typhoid Mary" in New York, such folks could cause a bunch of problems. They probably DO exist. We have NO IDEA how to spot them. And any one of them can get on an airplane and go anywhere in the world. They will never be detected because they have no signs of fever.
