A nurse is assessing an older patient and notes a cluster of fluid-filled vesicles on the right thoracic area. The nurse suspects HZ (Herpes Zoster). The patient asks the nurse. "I really don't understand how I got shingles. I don't even know anyone who has this infection." The nurse includes which of the following in formulating a response to the patient?

HZ is caused by a reactivation of dormant varicella zoster virus within the sensory neuron of the dorsal root ganglion

HZ is caused by the same virus as chickenpox and requires direct contact with an individual with HZ

HZ is caused by the same virus as chickenpox and requires exposure to an individual with active chickenpox

HZ is caused by the varicella zoster virus and occurs only in individuals who were never previously exposed to the virus
