Well the fact of the matter is, is that quite a number of Ebola patients have been treated in the west and so far, only these two in Texas and the Spanish nurse have fallen ill
In America, only in this Texas hospital did the patient, Duncan, initially walk into the hospital all on his own, on Thursday, September 25th, and touch and contaminate surfaces and come in contact with healthcare workers who were not suspecting he had Ebola and weren't wearing protective gear.
In the other hospitals the patients entered under the standard CDC protective protocols.
In all of the U.S. hospitals, many healthcare providers treated the patients.
In Texas, we are still within the 2 to 21 days incubation period
since Duncan walked in the first time on Thursday, September 25th.
If there was a breach in protocol of caring for an Ebola patient, a breach due to communications problems or whatever in the Texas hospital, we'd likely have a whole lot more than two of the 76+ healthcare workers who treated Duncan since his "official" Ebola entry on Sunday, September 28th, who'd be exhibiting symptoms by now.
No article I've read presents that "all healthcare workers who came in contact with Duncan on Thursday, September 25th, were immediately quarantined" and it is perhaps likely that the two healthcare workers who've come down with Ebola were contaminated on Thursday, September 25th, during their normal rounds.
The CDC is so "busy" focusing on care Duncan received while admitted to the hospital that they appear to be ignoring the very real possibility these workers contracted the virus on Thursday, September 25th, not on or after Sunday, September 28th.
Perhaps it's because the CDC can present the illusion of being in control of making changes in the former scenario or can blame it on personnel making a mistake, but are simply at the mercy of the circumstances of who picked up the virus on Thursday, September 25th, in the second scenario, something over which they have no damage-control "don't panic" line they can present at this point, that the CDC continues to talk about the post-9/28/14 contamination possibility .. but are completely ignoring the 9/25/14 contamination possibility which is the common method by which epidemics occur.
Friday, October 17th, will be 22 days after Duncan first walked into the hospital on Thursday, September 25th.
Then we'll see if any more of the 76+ healthcare workers who treated Duncan come down with Ebola.
