jjsheridan is exactly right. If you calculate HCW infected per patients treated, the US currently stands at 2.0, whereas west Africa is maybe 0.05. No comparison at all. African HCW are much better at controlling the spread in the HCW workforce.
Now admittedly, I’d prefer to be in the US as a patient, but that may change too. I understand they did things like intubate Duncan, which may be the sort of thing that new protocols will forbid, to limit disease spread.
Obviously the US has failed on keeping it contained, and hopefully the protocols will tighten up. But not sure the doctors to victims ratio is the way to look at it. Duncan probably had contact with numerous HCW (4? 8? 20?) I imagine that a single HCW in Liberia would see numerous patients. In one article about an Ebola ward in Liberia, of the 27 HCW it has had since it started this summer, something like 24 had died.
And of course, many of the victims in Liberia are turned away from the clinics and sent home to die.
