Pediculosis is a skin affection caused by lice, small insects that act as parasites. Lice feed on human blood and multiply between hair and hair, allowing them to move easily thanks to the hooks attached to their legs.
Most common symptoms and signs
- Burning eyes
- Discoloration of the skin
- Itching in the head
- Swollen lymph nodes
Infestations with lice occur worldwide and are among scabies among the most common ectoparasites in Europe. As ectoparasites, lice remain on the body surface of their host and trigger corresponding skin symptoms. Three types of pathogens affect humans: head, feet, and body lice; Animal lice are usually not found. The lice feed on blood and inject saliva into the skin while leads to itchy skin lesions. The females lay their eggs approx. 1 cm away from the hairline or in garment seams. After 8-10 days, the larvae hatch, laying eggs themselves about 10 days later. Development from egg to adult louse takes about 14-20 days. Every few hours, the lice suck blood, and after 2-3 days away from the human body they die. The eggs can survive about 10 days away from the host. In addition to hygienic measures, especially in the case of pediculosis capitis, a local drug therapy (eg with Dimeticon ) is required. In the case of felt lice, shaving and manual removal of lice and nits are often sufficient. Clothes lice hold each other usually on the garments on, so that additional treatment of the body is not necessary.
Epidemiology pediculosis “infection”
The source of the parasite is infected, people. The transmission path is a pin. The migration of lice increases with a decrease (if the source of the pathogen is a corpse) or an increase in body temperature (the source of the pathogen is a feverish person). Infections occur when they are placed on the market, in groups (children’s institutions), families, when they live in unhygienic conditions, with ordinary things (bed and underwear). The infection with the venereal disease almost always occurs during sexual intercourse: it is one of the most common diseases that are transmitted in this way.
The disease is very uncomfortable, its treatment depends on how fast the parasites were found. Symptoms that indicate that a person has lice on their eyelashes or eyebrows are as follows:
- Severe itching on the eyelids or on the eyelash roots, more often at night, because this is the time of maximum activity of insects;
- Swelling of the eyelids, sometimes in the morning, a person with difficulty can open his eyes;
- Appearance on the skin near the eyes pustules, with pressure on which the fluid is secreted, often pimples are formed in such places (see photos.
