Frequent use of pediculicides may cause persistent itching. Body lice can be vectors for diseases such as epidemic (louse-borne) typhus, trench fever, and louse-borne relapsing/recurrent fever. Violation of the integrity of the skin from a bite can lead to bacterial infection with organisms such as methicillin-resistant Staphylococcus aureus (MRSA). More commonly, infestation with lice produces social embarrassment and isolation rather than medical disease.
