@brianvastag @mackayim2022 I think the discussion is missing the point. We all learned decades ago in Medschool that these symptoms may (rarely) appear after various viral infections. What makes #LongCovid a completely new ballgame is the FREQUENCY at which the symptoms appear after one specific new virus. Reminds me of a pathology lecture I attended in the early 80s, where we were told that a sudden breakdown of the immune system in young men was nothing unusual and had been seen before….
