Zhou Has Covid--What's Up?

The Zerohedge headline reads:

Biden Tests Positive For Covid After Saying He'd Consider Dropping Out If Diagnosed With 'Medical Condition'

The problem here is that Zhou say he’d drop out if he got the flu or a cold or some other virus. Medical condition means, to me, some irreversible and debilitating condition, i.e., something even worse than dementia or Parkinson’s or whatever. I don’t think Covid qualifies for that. Well, you never know.

On the other hand, is this a way to get him out of the public eye for at least a week? He’s been screwing up every time he speaks so maybe the rationale would be, he doesn’t want to speak through a mask, or something like that. Anything to prevent him from being the target of questions about the Trump assassination attempt.
