Scabies infection is caused by the Sarcoptesscabiei, the human itch mite which thrives in the human skin. Female scabies mite burrows under the first layer of skin to lay eggs and then reproduce to increase the infestation which causes irritating rashes. The rashes are a result of the immune system’s response to the mite, their eggs and the fecal matter they leave behind. The mite cannot survive off the human body for more than 72 hours which makes it highly likely that the mite can find a new host, thus scabies is referred to as communicable disease.

Diagnosis of the infection

Once the initial symptoms of scabies infection are recognized, it is advised to get a physical examination of the affected area done by a doctor. The diagnosis involves removing the itch mite with a needle, scraping off a small section of the skin to identify fecal matter and the eggs.


Scabies can be treated by getting rid of the mite and its eggs with the use of prescription ointments, creams/lotions and oral medication. The creams and ointments should be preferably applied at night when the mite moves in the skin.
