Cameroon is over a thousand miles away from Liberia. And the Congo? I have not seen anything about reported cases of Ebola in the Congo (or Cameroon, for htat matter).
So, just to clarify, what you are saying is that every person from Cameroon should be treated as a potential Ebola carrier, and avoided at all costs?
The maps I looked at they were Google maps and they showed areas where Ebola had been found. I did not avoid the woman in the post office, we talked while waiting in a very slow line. So I guess the answer to your question is No, every person from Africa should not be avoided.
Is that enough, will you let this conversation pass? You can spend the rest of the evening searching for the maps I pulled up, just to keep yourself busy.
