We have an athlete in the house too, and I don’t think the reason it goes through teams is because parents take sick kids to practice. I am thinking it spreads more because kids at play actually TOUCH each other and breathe on each other, share the same ball, equipment.
My son is in a play this week and next week. So many kids have been sick. If he can hold out another week, I’ll be happy.
He says he has a habit of putting hand sanitizer on before he gets on stage, and when he comes off stage.
I also carry hand sanitizer in the car. When the get in, it goes on their hands.
We’ve been on several cruise ships, and I told them we are in cruise ship mode using lots of hand sanitizer.
