Chickenpox is caused by the varicella-zoster virus, a form of herpes. If a person contracts the virus, has an active infection and then recovers, the virus is not actually gone from the body. It can hide in nerve cells for years or decades, then emerge again to cause shingles, a painful condition that causes a skin rash and occurs mostly in adults.
