Won't believe he has it till we see some evidence of it, or of Hicks having it.
I know it doesn't make much sense to fake covid if he's still planning on trying to win this elecion, so I'll offer the scenario that it may now be about planning on how to lose the election, the best way for him. A path to stepping down and getting some Pence pardons writting up maybe?
Donald Trump's biggest worry is how fecked he is once he loses the protection of the presidency, he might well be royally and truly fecked. He loses his usefullness to his enablers and has lines of prosecuters with ready made cases just waiting for their moment.
Trump's team knows they can't win this election through the normal voting process, the only way is to cheat it. They will already know if it is possible, they already know the result.
