This short, excellent review from Centers for Disease Control, USA is worth reading in full!

“During the 1995 Ebola outbreak in Kikwit, Democratic Republic of Congo, 80 (25%) of the 315 case-patients were healthcare personnel, and all of the healthcare personnel who developed EVD had provided care to EVD patients without appropriate contact precautions.  In that outbreak, only one additional healthcare provider developed EVD after the hospital initiated barrier nursing precautions (this provider reported inadvertently rubbing her eyes with soiled gloves). During the 2007–2008 Ebola outbreak in Bundibugyo district, western Uganda, 14 healthcare personnel were infected before implementation of standard precautions and barrier nursing; none became infected after implementation of these precautions.”
