How many of the 240 that you cited or from doctors without Borders? According to their statements, only three. Are you aware how many healthcare professionals from poor Third World countries are currently treating Ebola victims?
Twenty-three MSF staff have been infected with Ebola since March, seven of whom have recovered. The vast majority of these infections were found to have occurred in the community.

I am aware that many healthcare workers from poor third world countries are treating Ebola patients. I know that many organizations like the Red Cross, WHO, Doctors Without Borders, Samaritan's Purse and others are working diligently to train local health care workers and provide upgraded facilities. This is a breakdown of their current staffing in the specific countries:
MSF Staff on the Ground (as of October 21, 2014)
Guinea: 54 international, approximately 360 national (+48 from Ministry of Health)
Liberia: 109 international, around 1,241 national
Sierra Leone: 107 international, around 1,417 national
Total: 270 international, around 3,018 national

* Doctors Without Borders/Médecins Sans Frontières (MSF) does not separately publish (or I could not find) numbers of trained health care workers in country vs support personnel. However, it is well known, and published on their site, that DWB/MSF internationally recruits only highly trained and qualified healthcare workers for field work. They prefer to hire support personnel locally. It is also known that the pool of qualified health care workers in Guinea, Liberia, and Sierra Leone has been decimated by disease. It is likely that 10% or less of their medical personnel are local. Therefore, Doctors Without Borders likely has less then 300 doctors and nurses on the front lines. ***Of those 300 likely healthcare workers, they have reported that 23 have contracted Ebola with 16 dying from it. Although it is a very small sample and probably not statistically significant, their mortality rate is 70%. The US mortality rate for US acquired infections is 0%.
***The 10% estimate is my educated opinion based on medical staffing and support information that I have access to but can not link here. In this setting, I will state that it is my opinion only.
