Lice and human health

Lice: A Parasite That Can Bring Disease

Introduction - what they are

Lice are parasites that host humans in two ways: on the scalp and on the body. The louse that parasites the scalp is known scientifically as Pediculus capitis. This type of louse produces irritations on the scalp due to the reactions of its bites, since these cause a dermatitis caused by the saliva reaction of this unwanted and uncomfortable parasite.

Health problems caused by lice

This irritation causes the host to scratch his head intensely, causing minor scalp injuries. These can facilitate the access of germs and bacteria into the bloodstream since the head is richly vascularized.

O Pediculus humanus corporis, can live in people's bodies and clothes. This insect usually lays its eggs on clothes. Prefer to live in colder climates, but can be found in more temperate climates.

Your bite also causes great irritation to the skin, as the reaction to your saliva usually triggers a very irritating papular dermatitis.

There is also the Pthyrius inguinalis, popularly known as "boring". These tiny insects use their sucking biting mouthparts to feed on their host's blood. Its location occurs in pubic hair, armpits, chest, etc. Currently they are not so frequent due to the evolution of personal hygiene habits.

For body pediculosis, treatment consists of maintaining personal hygiene, soaking clothes in cold water containing bactericidal and fungicidal disinfectant for at least two hours. Another option is to wash all family's clothing, including blankets, comforters, and sheets with hot water, however, this option can be replaced by ironing them on both sides.

The treatment for Pediculus capitis requires more caution as it is located on the head. In this case, it is appropriate to wash the head of the infected child or adult on a daily basis, daily comb the hair and remove the nits. In general, it is indicated to give preference to methods that do not employ piolhicides.
