AbstractVaricella zoster virus (VZV) is a pathogenic human herpes virus that causes chickenpox as a primary infection, after which it persists for a long time and latently in the peripheral ganglia. Decades later, the virus can reactivate spontaneously, or after exposure to a number of triggering factors, causing herpes zoster (shingles). The reasons for the long-term persistence of VZV are gradually being revealed, but some issues remain unknown at the moment. Chickenpox and its complications are especially difficult in immunocompromised patients, but they are often found in people without risk factors. The most frequent and important complication of VZV reactivation is postherpetic neuralgia; encephalitis, segmental motor weakness and myelopathy, cranial neuropathies, and gastrointestinal complications often develop. The only scientifically proven effective and affordable way of mass prevention at the moment is vaccination. Chickenpox vaccines are safe and effective in preventing morbidity and mortality associated with the disease.
