Cinder, good wishes being sent your way. Your snot-nosed student reminded me of a friend of mine whose kids kept coming home with head lice. She got frustrated and got permission to inspect the premises. A foreign language lab. The headphones were infested. since they were in constant use by different kids from different classes I mean grades, not social) and different ages. She went and bought whatever it would be to use to clean the darned things and started going to school and de-lousing them herself.
There ought to be something about basic sanitary habits.
In our school systems the school nurse does head checks about twice a year. If a student is found to have lice, they are sent home immediately with a note. They can't return to school until the head has been cleaned of lice and the nits. The nurse checks them again when they return.
