A "mite" seeps under the epidermis

Scabies is a parasitic dermatological disease caused by a "mite" that from its scientific name Sarcoptes scabiei hominis . This highly contagious infectious disease causes itching and skin lesions. It is not serious in itself but can be subject to bacterial superinfections.

The mite responsible for human scabies, the sarcopter, measures 300 microns and infiltrates under the epidermis. Only fertilized females cause infection because they are looking for a place to lay their eggs. Their movements under the skin are at the origin of the dermatological lesions, while their excrements cause an allergic inflammatory reaction responsible for the itching. The parasites lay about 3 to 5 eggs a day that hatch in 2 to 4 days. After two to three weeks of incubation, the larvae become adults whose life expectancy is approximately 2 months.

The major sign of scabies is a night-time rash, as females lay their eggs at night. The characteristic itching areas are at the spaces between the fingers, the anterior surface of the wrists, the elbows, the armpits, the areolas, the navel, the inner thighs, the bads, the knees and the knees. ankles.
