At this point, unless you've been living in a cabin in the woods, it's almost guaranteed you've had at least an asymptomatic infection.
I know people who never had symptoms, but tested because a household member had tested positive (with symptoms) and found out they were positive too - it happens.
In my opinion, that is the best case scenario - you got it, didn't know it and your body fought it off like a champ.
Definitely true. But there are some people who have been very careful and/or tested multiple times with every illness in the last 4 years, and who are fairly certain they have not had COVID.
