There is a student in the neighboring class who I overheard tell her teacher that her cousin has head lice. She was scratching her head during the conversation but mentioned that she and her cousin were treated. Fast forward two weeks later and she is scratching her head like crazy. She is not my student and when I mentioned it to her teacher the teacher said the parents already know. I didn't say anything more, especially because this teacher has decades of experience. So I am curious to know how you all treat a head lice situation?
