Transmission of Body Lice

Can Body Lice Transmit Disease?

Unlike head lice, which do not transmit disease, body lice can, in some cases, spread diseases. Epidemics of typhus and louse-borne relapsing fever have been caused by body lice, for example.
 
Though typhus is no longer widespread, epidemics still occur under the following conditions:
 
  • During times of war
  • During civil unrest
  • During natural disasters
  • In refugee camps
  • In prisons where people live crowded together in unsanitary conditions.
     
Typhus still exists in places where climate, chronic poverty, and social customs prevent regular changes and laundering of clothing.
