Abstract
Herpes zoster is caused by reactivation of latent varicella-zoster virus (VZV), typically occurring in older adults or immunocompromised individuals, and is rarely seen in infants. We report a rare case of herpes zoster in a 9-month-old infant, likely due to intrauterine exposure to VZV. The patient presented with dermatomally distributed vesicular lesions on the left anterior chest and back. Treatment included intravenous acyclovir, oral antiviral therapy, semiconductor laser therapy, boric acid compresses, and traditional Chinese herbal fumigation.
