Scabies is a skin infestation caused by the Sarcoptes scabiei mite, which burrows into the skin and causes intense itching and rash. The areas most commonly affected by scabies include intertriginous zones, which are regions where the skin folds or comes into contact with itself, such as the armpits, groin, and between the fingers. These areas provide a warm and moist environment that is conducive for the mites to thrive.

The infestation typically occurs in these skin folds because it offers the mites easier access to the skin and is often less exposed to environmental factors that may lead to their desiccation. The characteristic presentation includes small red bumps, burrows, and crusting, which are particularly pronounced in these regions.

Although scabies can also appear on the palms and soles and occasionally affect other areas including the scalp or face in specific cases (particularly in infants), the intertriginous zones remain the hallmark locations due to their favorable conditions for the mites.
