The authors cited studies suggesting that only 7 percent to 10 percent of long Covid patients fully recovered two years after developing long Covid. They added that “some manifestations of long Covid, including heart disease, diabetes, myalgic encephalomyelitis and dysautonomia are chronic conditions that last a lifetime.”
There was that study a week or two ago that suggested every covid infection comes with about a 3.5% risk of long covid if you’re immunized, and 7% if not. As a TTRPG player I can’t help but equate ~5% to rolling a Nat 1 on a D20.
