well as long as teh children aren't sharing pillows or head gear and have seperate cubbies for things like coats they should spread to much. lice can not live off a human body for more than 24 hours. please don't use the chemical pestisides in over the counter lice treatments on your daughter unless absolutely necessary. it is true that lice like clean hair, strange because ppl view it as a dirty thing to have lice, so use plenty of product and use a nit comb and check her hair daily, it's a hassle yes but the best way to get rid of lice to to make sure to get all of the eggs out of her hair. don't go overboard on you home you only need to really wash the clothing, and towels that she uses as well as the brushes and hair things and her bedding stuffed animals and such can get put up for a couple days and be just fine. my sd used to come home from her mother's with lice weekly so it's something we dealt with for months and never ahd anyone else get. also vinegar and mayo, the real stuff works to get the nits and lice out and is safer than the rid stuff. good luck
