Lice infestation in general is known as pediculosis, and occurs in many mammalian and bird species. [55] Lice infesting other host species are not the same organism as that which causes head lice infestations in humans, nor do the three louse species which infest humans infest any other host species. [citation needed]
Body lice frequently lay their eggs on or near the seams of clothing. They must feed on blood and usually only move to the skin to feed. They exist worldwide and infest people of all races. They can spread rapidly under crowded living conditions where hygiene is poor (homeless, refugees, victims of war or natural disasters). [4]
They can cause localized skin irritations and are vectors of several blood-borne diseases. Children appear particularly susceptible to attracting lice, possibly due to their fine hair. At least three species or subspecies of Anoplura are parasites of humans; the human condition of being infested with sucking lice is called pediculosis.
Head lice have been constant, if unwanted, human companions. The parasites are rich sources of genetic information illuminating big questions in the human story.
When your child is the temporary home for these blood-sucking freeloaders, the social issue can sometimes be more overwhelming than the physical issue.
Accordingly, the infestation with head lice is named pediculosis capitis, while this with body lice, pediculosis corporis. [ 1 ] [ 2 ] Although pediculosis in humans may properly refer to lice infestation of any part of the body, the term is sometimes used loosely to refer to pediculosis capitis , the infestation of the human head with the ...
[35] [37] Human lice can also shed light on human migratory patterns in prehistory. The dominating theory of anthropologists regarding human migration is the Out of Africa Hypothesis. Genetic diversity accumulates over time, and mutations occur at a relatively constant rate. Because there is more genetic diversity in African lice, the lice and ...
The body louse (Pediculus humanus humanus, also known as Pediculus humanus corporis) or the cootie is a hematophagic ectoparasite louse that infests humans. [1] It is one of three lice which infest humans, the other two being the head louse, and the crab louse or pubic louse.
