Who gets head lice?

Reports estimate that 10-12 million individuals are treated for head lice annually. Most cases are common, although not limited to, amongst school-aged children. Anyone who comes into head-to-head contact with an individual who already has a lice infestation is at risk. Personal hygiene and cleanliness in the home or school has nothing to do with getting lice. Head lice actually prefer clean hair. Spread by contact with clothing (such as hats, scarves, coats) or other personal items (such as combs, brushes, or towels) used by an infested person is uncommon.
