What the MSF leave out of this article is the number of their staff that are actually treating Ebola patients. Without knowing this critical piece of information we can't really know what the transmission rate is to staff.

Sure, it isn't deeply informative. Their other releases discuss treating hundreds of confirmed cases (and a multiple of that of people admitted to their treatment centers), so I guess we can presume that there are at least a similar number of personnel dealing with that treatment (even if they are severely limiting actual patient contact, they are still dealing with a lot of waste and so on). The religious hospital in the article had 10 personnel involved in treatment and 10 of them got infected. That's enough to at least direct your attention towards what the groups are doing differently (it could well come down to limiting care based on the ability to carry it out very carefully rather than training).
