The Ebola Virus hit West Africa with a peak in the autumn of 2014. A Liberian doctor named Gorbee Logan tried as a last resort the HIV- medicine Lamivudine that is a reverse transcriptase inhibitor since no therapy used until then had showed any effect.

To his pleasant surprise, it worked on 13 of a total of 13 patients that were treatable and not moribund when they presented themselves. But the Ebola virus should not have been defeated by a drug that blocks an enzyme that it should not have according to for instance Wikipedia.
There it is classified as a RNA-virus and not a retrovirus. Such a change of a virus metabolism cannot happen spontaneously. It has been made in the laboratory by splicing the genes that provides for replication in the HIV-virus into the Ebola-virus.

A little background information
The first retrovirus was found in sheep in Iceland. The virus, Visna-virus produced a disease called Visna and it caused the Sheep to waste/wizen and die typically after a couple of years. An Icelandic doctor, Bjoern Sigurdsson, who got funding from the Rockefeller foundation, isolated the virus. After Dr. Sigurdsson died at the young age of 46, American scientists continued the further research on retroviruses in American laboratories. The HIV virus is essentially a Visna-virus modified to infect humans. See link https://telegra.ph/Tamaida-Shimeras-blog-on-Coronavirus-Retrovirus-What-is-it-03-10
