It appears after the initial infection, it can go dormant in the nerve, and reactivate itself decades later.
In chickenpox - the symptoms are:
characteristic skin rash that forms small, itchy blisters, which eventually scab over. It usually starts on the chest, back, and face then spreads to the rest of the body
In shingles - the symptoms are:
a painful skin rash with blisters involving a limited area. Typically the rash occurs on either the left or right of the body or face in a single stripe.
My question is: What is the name of the property of viruses can activate a second time, with different symptoms?
