Nits are louse eggs and do not necessarily indicate an active infection. Which statement is true about nit management?

• A. They always signal an active infestation
• B. They may not indicate active infection
• C. They require systemic antifungal therapy
• D. They indicate imminent spread to others

Answer: (B)

Nits are louse eggs that attach firmly to hair shafts near the scalp. Their presence does not by itself prove an active infestation, because nits can persist after the lice have been killed or can be nonviable shells that will never hatch. Thus, seeing nits isn’t a reliable sign that someone is currently infested with live lice. In practice, management should focus on confirming active infestation by finding live lice, rather than assuming infestation from nits alone. If live lice are found, treat accordingly with approved pediculicides and thorough combing to remove nits, then recheck after about 7–10 days to ensure clearance and to catch any newly hatched lice. Routine systemic antifungal therapy is not indicated for nit management, and nit presence does not necessarily mean imminent spread to others.
