Preventing the spread of lice in a school setting primarily revolves around minimizing direct or indirect contact that allows lice to transfer from one person to another. By educating children not to share personal items such as hats, scarves, and combs, the likelihood of lice transmission is significantly reduced. Lice are adept at moving from one host to another through shared items, which is why this preventative measure is crucial.

The other options, while relevant to the management and treatment of lice, do not address the immediate need for prevention in a communal environment like a school. Reapplication of treatment, boiling or steaming bedding and clothing, and using nit combs are all important steps in managing an infestation, but they do not actively prevent lice from spreading within the school setting. Focusing on personal hygiene and avoiding sharing items is the first line of defense against the transmission of lice.
