Not sure if you will find evidence to support that. I have seen many anecdotal accounts of young healthy people becoming sick.
Response to icecoast1 above. Without data I think you are just flinging poo
Anecdotal accounts of young people getting sick does not make it worse than the flu. Never said young people dont get sick. But in terms of death rate, if you are young and healthy this is no worse than the flu. Data was already posted by someone else if you want to scroll back and find it
