The DNC has just confirmed that indeed, Joe has Long COVID with no expected date of recovery before the end of this election cycle.
In all seriousness, my mother entered in patient physical therapy after being discharged from the hospital for a broken leg in October 2020. She had a clean COVID antibody test upon entering the hospital but upon entry to the in patient rehab facility she tested positive on a PCR test (using a 40 cycle threshold!) and was placed in the COVID quarantine wing even though she was entirely asymptomatic for COVID at that time. Not surprisingly, after being placed in the COVID wing she came down with symptoms within 72 hours and was in a near coma delirium by the end of a week. She survived the COVID infection but began a rapid decline into dementia from which she never recovered and was never discharged from the nursing home. She was in far better cognitive shape than Joe Biden when she caught COVID but within six months was non-verbal and nonresponsive. She died within six months of catching COVID. When I visited her in December of 2020, she could carry on fairly lucid conversations but was hallucinating people that were not in the room with us. The cognitive effects of COVID on the elderly who have even the beginning stages of dementia can be rapid and dramatic. If it has a similar effect on Joe's cognition, he may not be able to appear in public again in just a very short time.
