Head lice

About Head lice

Tiny insects that live on the scalp. They feed on the blood of the infected person and are easily spread by close contact with other people. The infection can also be contracted through contact with infected furniture or by sharing brushes or bedding. There are several types of lice. Head lice live in the hair of the scalp, or eyebrows. Other types include body and pubic lice.

Symptoms

Intense itching, small bumps on the hair follicles (nits), small red bumps on the scalp.

Tests & Diagnostics

A history and physical exam will be performed. The lice may be difficult to see and more often the provider finds the characteristic eggs attached to the hair follicles (nits). A magnifying glass helps, and one needs to part the hair down to the scalp.
