It might all be smoke and mirrors, but assuming it's true, I suppose we'll find out soon if he really is the fittest president ever, as his doctor said.

Berlusconi had it a few weeks ago and started off in asymptomatic but ended up spending a few days in hospital. He's older than Trump but not carrying as much weight.

All of Trump's entourage refused to wear masks at the recent debate (against the rules, obviously) so depending on the distance they were able to keep Biden's lot might have been exposed to it too.
