How do we know they haven't?
A reporter on wfaa just commented that she was surprised a health care worker has a suspected case of Ebola yet the family in isolation has not exhibited any symptoms. Zach Thompson surprisingly replied not to be shocked if we have another case. The reporter then asked does that mean someone in the family has symptoms and Mr. Thompson did not say no but repeated again, “Don’t be shocked if there is another case”
Right we haven’t heard from his family since he died. Perhaps they have it and it is being kept secret for the CDC’s fear of a violent uprising seeing they were complicit in this happening here in the US.
