It seems disingenuous to imply that the effects of COVID are not worsened by a high body fat percentage and / or poor physical health.
COVID is not a fat persons disease, but as with most detrimental health episodes, the negative effects are greater in people with high body fat percentages.
I believe the initial rehousing of elderly patients back into nursing elder care facilities predates the arrival of the hospital ship and the construction of the Javitz Center hospital and triage space.
I'm ignorant on if this practice continued post arrival and construction of the added COVID treatment centers though.
