I remember getting my head checked in school nearly every year. There were always one or two kids sent home that were found to have some. Course we lived out in a small town and most of those kids were either around farm animals or wildlife which is how they usually got it.
There was a feeling of shame if you were one of those found with it. Even though it wasn’t really anything they did wrong. and of course the other kids made fun...with the boys it led to some of the ‘best’ fights. With the girls it often was the harbinger of friendship changes.
