Lice are obligatory parasites surviving on blood meals obtained from the host, with their mouthparts modified to enable piercing and sucking. The infestation with body lice, also known as pediculosis corporis, is a common worldwide problem that affects people of all races. Body lice are preferentially seen in cold climates, under conditions of poor sanitation and crowding. Pediculosis corporis is not only a disease in itself, but it can also be a source of bacterial infections. The hallmark of pediculosis corporis is pruritus and pyoderma of clothing covered areas. A more general reaction of fever, headaches, a diffuse rash, fatigue, and myalgias may appear a few weeks or months after the beginning of the parasitism. Treatment is comprised of improved hygiene and laundering of all the infested clothing, bedding and linens in hot water. Medical treatment involving pediculicides is required in large-scale infestations.
虱子是专性寄生虫，靠从宿主获取的血餐生存，其口器经过改造以实现穿刺和吸血。体虱感染，也称为体虱病，是一个影响所有种族人群的全球性常见问题。体虱在寒冷气候、卫生条件差和人群拥挤的情况下更容易出现。体虱病不仅本身是一种疾病，还可能是细菌感染的源头。体虱病的标志是衣物覆盖部位的瘙痒和脓皮病。在寄生开始几周或几个月后，可能会出现更普遍的发热、头痛、弥漫性皮疹、疲劳和肌痛反应。治疗包括改善卫生状况以及将所有受感染的衣物、被褥和床单用热水清洗。大规模感染时需要使用杀虱剂进行药物治疗。
