Head lice are commonly seen in which group?

• A. Adults in offices.
• B. School-aged children.
• C. Elderly people.
• D. Infants.

Answer: (B)

Head lice spread mainly through close head-to-head contact and by sharing personal items like combs, hats, or pillows. School-aged children are most commonly affected because they spend long periods in close proximity and frequently exchange items, making transmission easy. In contrast, adults in workplaces, elderly people, and infants have less frequent direct scalp contact and fewer opportunities to share items, so lice are less common in these groups. This understanding helps explain why screening and preventive education are especially important in school settings and for households with children.
