Hell...we have a problem right now in our child care services in the military because people got complacent at one Post (I believe it was Fort Gordon) and now every worker has to be vetted with 8 different types of background checks including psych screenings. Hell...its harder today to be a childcare worker in the Army civil service than it is to get a TS clearance.
People make mistakes. They miss things. Even professionals.
And as an edit...if it the infection occurred during his actual visit...it wasnt even about a lack of professionalism or complacency.
But, could be that the CDC created new protocols for American hospitals they're not up to snuff. A lot of variables here but all possibilities should be on the table with the response created and implemented to deal with the worst possible scenario.
I agree it is worrying but there are other factors to consider.
Many Journalists have been covering the Ebola crisis for some time and have been wearing protective gear, they have gone into Liberian hospitals and treatment centers and as far as I know, none of them have come down with the virus.
The incubation period is long enough that it'll be some time before we know if the infectiousness of the disease has increased, but the fact of the matter is, is that Monrovia for example has just over 400, 000 people, if this disease has become more infectious, it's gonna light up like the 4th of July within that city.
I believe that Thomas Duncan knew that ebola was in his future when he came to the US because he had contacted carriers in Africa. He believed that American doctors had success with other cases and his only chance for survival was here. In the process he is guilty of attempted murder if the health care worker recovers and murder if she doesn't, even though it's a moot point because he's dead. Jesse Jackson can stuff it.
