As with HSV-1 and HSV-2, VZV establishes latency in sensory or autonomic ganglia following primary infection, with the ability for subsequent reactivation. The primary acquisition of VZV results in the clinical disease varicella (chickenpox) with reactivation from latency resulting in zoster (shingles). Live-attenuated varicella vaccine was licensed in the United States in 1995 and, over the past 20 years, has substantially altered the epidemiology of the disease in this country, with rates of varicella and its complications plummeting.
