Minister of Information, Lewis Brown, disclosed this to reporters in Monrovia, the Liberian capital.
He said it was sad that although the late medical doctor was able to walk around on Sunday and his doctors were hopeful that he would make a full recovery, he still died.
Meanwhile, Doctor Phillip Zokonis Ireland who was in isolation along with Borbor, has tested negative and has been discharged.
Updating on progress by government on Ebola sensitisation, Brown said community residents are now actively involved and the dissemination of Ebola messages is encouraging.
The minister added that government has conducted a two-day awareness workshop in various communities to determine the response of citizens indicating that the people are now better situated in the fight to prevent spread of the virus.
