Here is a link for an interview with a doctor saying that Vitamin stores are wiped out by Ebola and other hemorrhagic fevers. There were no scientific references listed, but Dr. Levy’s book is listed at the end. I Googled “Vitamin C stores destroyed by Ebola Virus” and several things came up saying that happened, but I did not see a scientific reference on the first page.

I’m dubious.
A number of things happen in end stage scurvy that don’t happen in Ebola, teeth loosen, old fractures break again, old scars open.
The main killer in Ebola is the diarrhea and vomiting; bleeding is a factor in a minority of cases. Neither are features of scurvy.
The bleeding seems to be a result of disseminated intravascular coagulation. Micro-clots form throughout the body, using up fibrin, a clotting protein. Then there is no more fibrin, and small injuries bleed uncontrollably.
