The infection of two Texas nurses who treated Thomas Eric
Duncan, a Liberian patient with Ebola, has
exposed serious holes in the preparedness of US hospitals to
treat the virus.
The Centers for Disease Control and Prevention are now
investigating the procedures at Texas Health
Presbyterian, where the healthcare workers became infected,
including which protective equipment is being used and how
it is being put on, the decontamination process once workers
leave the isolation unit, and the training provided to hospital
workers.
The CDC still does not know how the latest Ebola patient
contracted the virus, but it is clear that even extremely minor
oversights while following hospital protocols can increase the
risk of getting Ebola.
To illustrate how easy it is to spread Ebola from patient to
worker, CNN's Sanjay Gupta demonstrated in a video how a
worker would generally suit up and then remove his or her
protective gear when following the CDC's guidelines.
Gupta uses chocolate sauce to represent Ebola.
First, Gupta puts on his full-body suit.

Next someone pours chocolate sauce into his hands to represent the Ebola virus.

Gupta rubs his hands together. The gloves would be the most likely contaminated area, he says.

The front of the gown can also be easily contaminated
if the worker smears his or her hands
across it. Gupta then demonstrates how the gown
would typically be removed, ripping it off in one
motion. If part of the glove brushed across his bare
hand as he was removing the gown, then that could
be a potential exposure, he says.If his face-shield
were contaminated, then the virus could also be
transferred to his neck as he lifts the mask over
his head.

Removing the face mask poses the same issue.

After all his protective clothing is removed, Gupta points out that he has chocolate sauce
(Ebola) on his arm.

There's also some stuff on his neck.

Gupta says this method may work in many hospital situations
but that three things "really jumped out at him" as being
problematic. First, not all of his skin was covered, which could
be an issue "if there was some splattering from a patient who
was sick." Second, Gupta says that in pictures provided by the
CDC, there is no "buddy system," or someone who checks
workers when they put on their garb and when they remove it.
Lastly, he notes that there's no specific requirement for
cleaning one's hands before taking off the gloves.
