I was wondering if there are any laws prohibiting school districts from sending home a letter to parents when lice is found in the classroom. Obviously, confidentiality would be protected. Is there anything that states we need to have 3 or more students with lice before a letter can be sent? I am located in the state of WI, btw. I get both sides- parents want and should be alerted with cases of head lice, but also, confidentiality should always be a priority. Any help from school nurses about laws/policies regarding this would be greatly appreciated.
