Herpes zoster in infancy.

Herpes zoster (HZ) in infancy is considered rare as both primary infection with varicella-zoster virus (VZV) and the reactivation of latent VZV would have to occur in the first year of life. We report a case of HZ, in an otherwise immunocompetent young infant, with a previous history of neonatal varicella. This case highlights the clinical presentation, management strategies and potential complications of infantile HZ, with a discussion of relevant literature. We advocate for a high index of clinical suspicion for infants who present with crusted lesions limited to one or two dermatomes to facilitate timely intervention, as well as long-term follow-up to improve clinical outcomes.
