Cellulitis can complicate varicella and may be identified by larger margins of erythema surrounding the vesicles. One study identified patients with invasive GAS cellulitis complicating varicella. [35] The median onset of GAS infection was day 4 of varicella, with fever, vomiting, and localized swelling reported. This condition mandates antibiotic treatment and careful clinical follow-up. Untreated cellulitis in association with varicella may progress to severe necrotizing soft-tissue infections requiring surgical intervention. [36]
