I was under the impression that the Spanish flu was very different from the regular flu and COVID-19, because it was the young/old people that survived it and the healthy 20-50 year old that died the most. Most people died of the Spanish Flu because of their immune response. It looks like COVID-19 is really mild* for lots of people in that age group.
Am I missing something? Did the Spanish flu start like COVID-19 and evolved later?
