can I give my nine month old some orange juice?

Last night one of my husbands friends came over and he didn't tell us he had tonsillitis until after he held my son. 😑 so after he left I gave my son a bath and I'm wondering what else I can do to make sure he doesn't get it. I usually drink orange juice to get anything away. So I'm wondering if I can give him some in a sippy? Or any other recommendations would be great.
