Study on the routes of Demodex mites transmission

Background and Aim : The mites Demodex folliculorum and Demodex brevis are ubiquitous andobligatory ectoparasites typically found on man, they asymptomatically inhabit the pilo-sebaceousunits of adults. The two species mainly involve the face and the head, but Demodex brevis has awider distribution on body, these mites are affecting most commonly the perioral, periorbital areasof the face, the lids and lashes. Demodex infestation is relatively common, and is only rarelyassociated with disease. Occasionally, mite populations can expand, resulting in a condition calleddemodicosis, which causes itching, inflammation, redness, acne, rosacea, hairloss etc.Methods : after studing many articles with key words: Demodex mites, demodex transmissionand demodicosis; from databases such as Pubmed, Researchgate, google scholar and etc, data havecollected.Results : Demodex mites can be found in any age groups except the new-borns who arepresumably infested soon after birth by direct; it is more commonly encountered in young adultwhen the sebum secretion rate is at its highest. Infection can be transmitted indirectly throughhousehold items, as it was shown that the mites can long enough to remain viable outside the host,Demodex can be transferred by contaminated towels, combs, blankets, bath sponge and nightclothes. In addition, practitioners often advise patients to start washing their bed sheets andpillowcases regularly in hopes of preventing re-inoculation. In severe cases, patients may evenneed to consider replacing their pillows altogether.Conclusion : Demodex are permanent ectoparasite of dermatological importance and it has beenshown that these mites are playing an important role in the occurrence of a series of skin diseases.Because Demodex are nocturnal, it is important to limit their ability to reproduce and migrate whenthey are most active. On the other hand, Transmission of demodex has proved. Demodex infectioncan be transmitted directly by close contact with the infected people. The mites are transferredbetween hosts through contact of hair, eyebrows and sebaceous glands. In addition, Makeupcosmetics used by different individuals at short intervals (from several hours to several days) canbe a source of transmission of Demodex sp. mites. These Demodex transmission ways are commonbut overlooked. We strongly recommend if you have density of demodex remember health tips,preferentially; in hopes of preventing re-inoculation.
