He's fine. He's gonna be fine.
I don't think, at this stage, anyone can know for sure how things are going to turn out.
The key time, for anyone who's proved symptomatic, is a week to ten days after they first tested positive, at which point their immune system either will have fought off the virus or goes into overdrive as the infection spreads to the lungs.
Boris Johnson announced on Friday March 27 that he'd tested positive. His symptoms were comparatively mild until Sunday April 5, when he was admitted to hospital with breathing problems and moved to the ICU on the evening of Monday April 6. Until then, he was isolating in the flat at 10 Downing Street, chaired cabinet meetings remotely, and worked on his Red Boxes as best he could. That's in line with everything else I've read and NHS treatment policy, and
with your CDC guidance.
Among patients who developed severe disease, the median time to dyspnea from the onset of illness or symptoms ranged from 5 to 8 days, the median time to acute respiratory distress syndrome (ARDS) from the onset of illness or symptoms ranged from 8 to 12 days, and the median time to ICU admission from the onset of illness or symptoms ranged from 10 to 12 days. Clinicians should be aware of the potential for some patients to rapidly deteriorate one week after illness onset.
So I don't think anyone, including Trump's doctors, can know what sort of shape he's going to be in this time next week.
