Abstract
We report a 40 day-old infant with late onset group A cellulitis and sepsis presented with fever and neck swelling with redness and tenderness. He was seriously affected and ventilated. Group A streptococcus (GAS) was isolated from blood within 24 hours. He was dramatically improved with proper antibiotics and discharged home in good condition. Mother was healthy. We believe that the source of GAS was one of his brothers with tonsillitis, but no evaluation was done to confirm it.
