As some said early on, the evidence seems to point toward improperly followed procedures. I was thinking about how one would remove a pair of latex gloves after handling an Ebola patient without contaminating oneself. Once you've pulled the right one off, how do you pull the left one off without touching it with your right hand.
So they double-glove, but I don't understand how that solves the problem. You pull the right one off, then contaminate the one underneath it when you pull the left one off. Same problem.
So they must disinfect, pull off the outer gloves, then disinfect again, then pull off the inner gloves. Or maybe they have glove puller-offers?
And that's just the gloves. How does one remove one of those outfits with headgear and gloves without contaminating something?
So after thinking about this I'm still not so sure the possibility the virus isn't more virulent than it was before can be eliminated. There
*have* been some minor genetic changes - in fact, the changes help track the pathway of the disease through human populations. Maybe it's just a little more resistant to disinfectant? Maybe it survives outside the body just a little longer? Maybe it adheres to surfaces just a little better?
