Lice

Lice are small, wingless, parasitic insects that feed on human blood. They are found worldwide and infest people of all ages and socioeconomic classes. Lice infestations (pediculosis) are spread most commonly by close person-to-person contact. Dogs, cats, and other pets do not play a role in the transmission of human lice.

Types of Lice

There are three types of lice that infest humans:

• Head lice - These lice are found on the scalp. They are the most common and can cause intense itching.
• Body lice - These lice live in clothing and bedding and move to the skin to feed. Body lice infestations can spread diseases.
• Pubic lice - Also known as "crabs," these lice occur on the hair and skin of the pubic area. They also may attach to coarse hair elsewhere on the body (for example, eyebrows, eyelashes, beard, mustache, chest, armpits, etc.).

Symptoms

The most common symptom of lice infestation is itching. Other symptoms may include a feeling of something moving in the hair, an allergic reaction to the bites, irritability, and difficulty sleeping.

Treatment

Treatment for lice may include over-the-counter or prescription medications, depending on the type of lice. It's important to follow the treatment instructions exactly to get rid of the lice.

Prevention

Prevention of lice infestations involves avoiding close contact with an infested person and their belongings, especially items like hats, scarves, coats, combs, brushes, and towels.
