Picture of Scabies
Scabies is an infection caused by a mite called Sarcoptes scabiei. The mites burrow under the skin causing red, itchy bumps. Closer examination of the skin with a magnifying glass reveals lines under the skin, which are produced by the mites burrowing. Scabicide medications are used to treat the infestation.
