How scabies are caught

Scabies is a very contagious skin disease caused by infestation with a type of microscopic mite called Sarcoptes scabiei var. hominis. The parasite mites responsible for causing scabies can be easily contracted by entering in contact with infested persons. Scabies can also be acquired indirectly, by entering in contact with contaminated objects. Although scabies mites can live for a few days without a human host, recent studies have revealed that scabies is rarely acquired indirectly.
Once they find a human host, scabies mites quickly populate the skin, hiding in less exposed regions of the body. Female mites usually lay their eggs under the fingernails, in the skin folds between the toes or fingers, in the pubic region, in the areas of the buttocks or the upper back, in armpits and the region of the elbows. The first symptoms generated by scabies are skin inflammation, itch and rash. In later stages of the mite infestation, people can also develop skin ulcerations, lesions, blisters, pustules, crust and painful nodules. Most of the symptoms caused by scabies occur due to allergic reactions to the mites -
Treatment can be by several means, however scabies have become increasingly resistant to chemical treatments "Reported Sarcoptes scabiei (scabies) treatment failures with lindane, crotamiton, and benzyl benzoate, as well as likely emerging resistance to 5% permethrin and oral ivermectin, are of concern and advocate for the identification and development of novel acaricidal drugs"

A highly successful and natural scabies treatment is with cream, oil and soap containing Manuka and tea tree oils. The scabies mites are yet to develop any recorded resistance to these natural essential oils and they also have no known side effects.
