I think this is still under study. I've heard a number of 67% of mild/asympotmatic cases having evidence of lung damage (https://www.npr.org/sections/goatsandsoda/2020/06/23/864536258/we-still-dont-fully-understand-the-label-asymptomatic https://www.npr.org/sections/goatsandsoda/2020/06/23/8645362... says 57%). I also saw an interview with an Israeli Dr. who is doing a study (that study is in progress) who said significant numbers suffer from symptoms like fatigue, shortness of breath (I think this may be the same one: https://www.timesofisrael.com/its-frightening-doctors-say-half-of-cured-covid-patients-still-suffer/ https://www.timesofisrael.com/its-frightening-doctors-say-ha... ). I think the bottom line is we don't know for sure but if needed a little more evidence this isn't just a walk in the park I think we got some.
