I think that Trump has been part of the Plan since he entered NYMA where he was educated to become a key person in the overthrow of the Cabal. By the time he proved himself in business, he was likely selected as one of a very short list to fill the role of President commanding the military force which would take out the criminals. By that time the epidemic plans would also have been known.
So, I think his aversion to germs was all kayfabe, setting the stage for today. They thought that they could use his aversion to reinforce the epidemic, but it turns out, Trump has no such fear.
