Just hours after the revelation that the lethal Ebola virus had spread to the United States, at least two quarantine experts were urgently dispatched to Liberia’s international airport to check for holes in its system of passenger health checks.
It was from Roberts International Airport, just outside Monrovia, that a Liberian man named Thomas Eric Duncan boarded a flight on Sept. 19, while he was still in the incubation period for the Ebola virus.
Then our friends from the CDC were quoted as saying (emphasis mine):
“We’ve already sent a team out to the airport today [Wednesday] to see if we missed something, and so far we see that we haven’t,” said Tom Kenyon, director of the Center for Global Health at the U.S. Centers for Disease Control and Prevention.
“There were no signs of any disease when the gentleman boarded the flight here – no fever or signs or symptoms or reported exposure,” Dr. Kenyon told reporters at the U.S. embassy in Monrovia on Wednesday.
We know that this information is incorrect – Duncan had direct and prolonged exposure to at least two known Ebola victims, Marthalene Williams, a pregnant lady who lived in the house where he rented a room from her parents, and her brother Sonny Boy, who was with Duncan and Williams in the taxi hours before she died when Duncan was attempting to assist her during the transport to the hospital and who remained in close contact with her when she returned home. Sonny Boy also perished days later.   The NYT (which never, ever lies to us!) quotes the family of Marthalene and Sonny Boy as stating:

“Sonny Boy, 21, also started getting sick about a week ago, his family said, around the same time that Mr. Duncan first started showing symptoms.
If the CDC is correct, and there was “no reported exposure”, then Dallas patient Duncan deliberately and fraudulently did not report his direct and prolonged contact with at least two ebola victims and also denied that he was presently symptomatic – something that the family of the deceased claims he was before he abruptly left Liberia for the US.

Or – alternatively – the CDC trained airport screeners did not ask him about “exposure” to ebola victims, which is one of the keystones of the Obama rationale for not grounding flights originating in the contagion zone.
Apparently the Obama administration solution is to put every potential passenger originating in the outbreak zone on a “Scout’s Honor” system of self-reporting and voluntary quarantine.
Read the entire article here, which also includes an embedded video about the gaps in the “airport screening” method.
Apparently the known fact that the outbreak is following an “unusual” pattern and epidemiologists back in April could not identify the source of the outbreak is no biggie.

While countries are shutting their borders and other flagged airlines are voluntarily grounding their aircraft and refunding ticket purchases in an effort to contain the outbreak stating
“The safety of our customers, crew and ground teams is always our top priority and we will keep the routes under constant review in the coming weeks”
the Obama administration in contrast to the rest of the world has doubled down and the CDC has instructed hospitals and funeral homes to “prepare” to manage large numbers of ebola patients.
Obama spokesperson Josh Earnest stated the official on-the-record US position:
The White House said Wednesday it will not impose travel restrictions or introduce new airport screenings to prevent additional cases of Ebola from entering the United States…current anti-Ebola measures, which include screenings in West African airports and observation of passengers in the United States, will be sufficient to prevent the “wide spread” of the virus.
