Risk factors for body lice infestation include close, crowded living situations (eg, crowded buses and trains, prison camps) [11] and infrequent washing and/or changing of clothing. P corporis can be acquired via bedding, towels, or clothing recently used by an individual infested with lice; thus, individuals who are homeless, who are impoverished, or who are living in refugee camps are at high risk for infestation.
