If not only the white blood cell level is high, but also the mental state is poor, always drowsy, often with fever and very poor milk intake, and the blood culture of the child indicates bacterial multiplication in the blood, this should be considered to be caused by sepsis, and the child should be given cephalosporin anti-infection in a timely manner.
