Scabies is caused by an infection of scabies mites and is highly contagious, generally being transmitted through direct contact, such as sharing clothes or sleeping in the same bed with shared bedding. Typically, the itching is milder during the day and worsens at night. Symptoms include itching, peeling, and blistering between the fingers. In males, red scabies nodules may appear on the scrotum. Chickenpox, caused by the varicella-zoster virus, is also highly contagious but primarily spreads through droplets and air. Once infected, it can be treated with antiviral medications. Scabies and chickenpox are entirely different diseases and must be diagnosed and treated separately.
