Chickenpox, also known as varicella, is a highly contagious disease caused by the initial infection with varicella zoster virus (VZV).The disease results in a characteristic skin rash that forms small, itchy blisters, which eventually scab over.fter a chickenpox infection, the virus remains dormant in the body's nerve tissues.
