To prevent body lice, a person should bathe and wash clothing regularly. Head lice can be easily spread when people share sleeping mats, combs, brushes, hats, helmets, and other headgear.
If lice are not treated promptly and effectively, the individual may have chronic itching and inflamed skin. Severe long-term untreated cases of body lice can lead to loss of energy and infections.
Both types of lice are highly contagious.
