Most people have no obvious long term symptoms from infection. Some % have symptoms like no or distorted sense of smell, heart issues, lung issues, etc for more than a year. Vaccination seems to reduce the odds you'll have these problems. My guess is serious lingering symptoms 5% for kids and more like 10% for sub-50 adults. Hard to get good data though, the best I've seen is this survey from the UK: https://www.ons.gov.uk/peoplepopulationandcommunity/healthandsocialcare/conditionsanddiseases/bulletins/prevalenceofongoingsymptomsfollowingcoronaviruscovid19infectionintheuk/1april2021 https://www.ons.gov.uk/peoplepopulationandcommunity/healthan... All this to say there will be fortunes built on the expansion of the market for chronic disease management tools.
