What the CDC Says About Lice
The CDC describes lice as tiny parasitic insects that spread through direct head-to-head contact. Head lice are not known to spread disease, but they can cause itching and discomfort.
How Lice Spread and Who Is at Risk
Lice move by crawling and are mainly spread through close contact or shared personal items like combs and hats. Children and household members of infested people are at highest risk.
CDC-Recommended Steps for Treatment and Prevention
The CDC recommends using an approved lice treatment, removing nits with a fine-toothed comb, and washing bedding and clothing in hot water. Avoid sharing personal items and check household members regularly for early detection.
