A second person in Dallas has contracted Ebola, a health care worker that had close contact with the guy who died last week. The CDC says that she contracted it because of a "protocol breach", but then noted they were unable to identify what the breach was:
A top federal health official says a health worker diagnosed with Ebola has been unable to identify a breach in procedures that might have led to her infection.
This goes back to my original question on this topic over a month ago: how are people who are specially trained in avoiding catching this horrible virus somehow catching it? Maybe the first US doctor who caught it over in West Africa was a victim of his surroundings - substandard cleaning areas, not enough powerful chemicals, etc. But how do you explain a worker who is literally under a microscope in how this virus is being treated in the States somehow screwed up, and did something wrong? Doesn't pass the smell test.
Either what we think we know about how this virus is imcomplete, or the virus itself is mutating.
