Causes of Body Lice (Cont.)

Risk Factors for Body Lice

Anyone who comes in contact with clothing, beds, bed linens, or towels of an infested person is at risk for body lice. Skin-to-skin contact with someone who already has body lice also increases the risk that an infestation will be spread.
 
Body lice infestation is common, found worldwide, and affects people of all races. Such infestations spread rapidly under crowded conditions where hygiene is poor and where there is frequent contact among people.
 
In the United States and other developed countries, body lice are found mainly in homeless, transient populations who don't have access to changes of clothes or baths. Infestation is unlikely to persist on anyone who bathes regularly and who regularly has access to freshly laundered clothing and bedding.
