Right. Infected and infectious are two different things.
However, there are grey areas here. Low risk of infection is not zero risk of infection. When dealing with a disease with a mortality rate of 50% or more, and such variable incubation times, “low risk” has a somewhat different meaning than if we were talking about initial stages of a low mortality disease.
Moreover, what if a low risk carrier comes into contact with a high risk (say, a compromised immune system) recipient? How many virons does it take to infect such a person?
Yes, that is correct, what about those people? Children, old people, people who are already sick in some way?
They really are making only the most cursory attempts to keep people with ebola out of the country.
And this idea of: we can contain it, it won’t be widespread, well that’s not a lot of help to anyone, like that poor nurse, who DOES get it.
Britain stopped flights, France stopped flights, the Saudis wouldn’t let anyone come there for the Haaj (very good idea and I’m glad they did it), so you know, what’s the problem?
I’m sorry, nobody needs to come here from Liberia, etc. right now. Come later.
