You are correct except that it is 416 infected and 233 dead medical professionals in Africa. The procedures are inadequate. Even if 416 people who knew their lives depended on it violated procedures. The procedures should be designed so that a non-specialist working long hours and with a real-world level of training can follow them well enough to survive. Otherwise, the procedures are by definition defective.
Well, 233 is more than 100. ;-)
But I agree.
