I don't know the answer to your question of whether other countries fund development of Marburg or Ebola treatments. I believe at the time the DoD funded it out of pure national self-interest: regardless of geographic proximity, just one infected person on the wrong flight could present a massive national security risk. To be fair the DoD did continue funding Ebola cures with Tekmira, and Tekmira earlier this year began dosing of the first human patient. That patient is healthy and the dosing is to test the safety profile of the drug. Reportedly the WHO has not requested any emergency supplies of Tekmira's drug yet.
