If a child has 3-5 white blood cells in the stool, this is an abnormality. The increase in white blood cells in the stool of children is usually caused mainly by bacterial enteritis. The exact cause of bacterial enteritis is mostly caused by eating poorly, often due to children grabbing things with their hands and licking their fingers with their mouths, which leads to bacteria entering through the mouth, resulting in increased white blood cells in the stool. In addition to leukocytosis, children often have abdominal pain, diarrhea, mucus and pus and blood in the stool. At this time, the child can be given timely anti-infection treatment with cephalosporins. If cephalosporins are used, third-generation cephalosporins need to be applied, and the course of treatment is mostly 7-10 days. If the treatment is not complete, it will lead to recurrence of fever and prolonged enteritis in children, which is more troublesome.
