Chickenpox is a highly contagious disease caused by primary infection with varicella zoster virus (VZV). It usually starts with a vesicular skin rash mainly on the body and head rather than on the limbs. The rash develops into itchy raw pockmarks which mostly heal without scarring. On examination the observer typically finds skin lesions at various stages of healing and also ulcers in the oral cavity and tonsil areas.
