Then why the mask? Theater?
My mom works in a hospital where they send admitted elderly COVID positive patients home with mild symptoms all the time. Not admitting them for the infection but instead a lot of people catch COVID when going for other procedures. In fact, they don't even re-test people for COVID before discharging them as you can test positive for COVID 3 months after your initial symptoms. All they do is treat the mild symptoms, take a chest X-Ray, do some bloodwork, use a pulse oximeter to make sure your oxygen levels don't drop and tell those to quarantine for a couple of days if they haven't hit that 5 day marker after initial infection.
They don't really even prescribe paxlovid in a lot of cases.
So Biden being positive for COVID doesn't mean he's contagious anymore.
Is it April of 2020 again?
