Answer

The diagnosis of body lice depends on the close examination of the patient's clothing for crawling lice and nits. The inner seams of clothing worn on the axillae and groin regions are common sites of residence. Occasionally, a body louse may be seen feeding or crawling on the skin. The number of body lice per host is usually approximately 10, although as many as 1000 lice can be present in clothing. [11]
