Neonatal varicella and early-onset herpes zoster following maternal infection at term: a case report

This case highlights that neonatal varicella can occur despite intravenous immunoglobulin prophylaxis and strict isolation, and early-onset herpes zoster may follow perinatal exposure. Close follow-up of exposed neonates is crucial, and further research is needed to better understand the protective efficacy of intravenous immunoglobulin and the mechanisms of early varicella zoster virus reactivation in infancy.
