He's over 70 and fat, which isn't great. But otherwise his health seems fine, likely from having good genetics rather than a healthy lifestyle or diet. He's not diabetic, he doesn't have heart disease, and no auto immune problems or cancer. So his risk factors are pretty low. Worse case scenario he'll suffer a moderately bad illness, maybe needing a brief hospital stay with low flow oxygen support. More likely he'll suffer a mild cold. He'll be taking preventatives, an anti-viral, a prophylactic antibiotic in case of secondary infection, and he'll be put on Dexamethasone on any indications of respiratory impairment. They'll be constantly monitoring his vitals, particularly his blood oxygen saturation. Boris Johnson got sick because he was pre-diabetic and likely insulin resistant due to his weight, and that's the primary concern for Trump, along with his age. Anyway I don't think there's much chance that the orange man will be meeting his maker.
