Children are prone to diarrhea due to the immature development of their gastrointestinal tract, with viral infections being very common among them. The most common virus causing diarrhea in children is the rotavirus. Initially, children may show symptoms similar to a cold, followed by watery or soup-like stools. Children can easily become dehydrated and suffer from electrolyte imbalances, so it is crucial to seek medical attention promptly. Another common virus causing diarrhea in children, similar to rotavirus but often more severe, is the norovirus. Norovirus also damages the intestinal mucosa, leading to watery stools and rapid dehydration and electrolyte imbalances. Therefore, it's essential to be highly vigilant and take preventive measures against these viral infections.
