## **Core Concept**
Scabies is a skin infestation caused by the mite *Sarcoptes scabiei*. It is characterized by intense itching, typically worse at night, and a pimple-like skin rash. The condition is highly contagious and spreads through direct skin-to-skin contact.

## **Why the Correct Answer is Right**
