Do you think the nurse deliberately infected herself?
Or do you think she became infected by simply being human and making a mistake...?
I suspect the protocols for protecting oneself from the disease are inadequate.
A procedure which requires the nurse to always be 100% perfect is a bad procedure.
A workable procedure should be multi-layered so that multiple things have to go wrong in order for bad things to happen. Murphy's Law should be taken into account.
Neither. I think this illness is far easier to spread than the "authorities" dare let us know. All they have been saying is how it takes direct contact with body fluids, from someone who has to be symptomatic, etc etc. The incidents of infection after almost trivial proximity, in some cases, tell a different story than the flunkies and mouthpieces.
90 health care workers in West Africa have caught the disease and died, including four doctors that we know about, and many nurses. These are people well versed in sterile precautions and protocols. Do you think they all died because they were "simply human?"
