Acute Diarrhea in Children Guarino

By definition, acute diarrhea consists of a change in stool consistency (soft or liquid) and/or an increase in the number (≥ 3/d). The duration is generally less than 7 days. In Europe, children under 3 years old have 0.5 to 2 episodes of acute diarrhea per year. These are mainly Rotavirus infections, while Campylobacter and Salmonella are the bacteria most often involved.

The complication of acute diarrhea is the occurrence of dehydration. This risk is significant in children under 6 months, especially for those in the community, due in particular to greater exposure to Rotavirus. Children with chronic pathologies (immune deficiencies, associated malnutrition, cancer, chronic inflammatory bowel diseases) are also at greater risk of severe acute diarrhea.

The management of acute diarrhea is based on the use of oral rehydration solutions (ORS) ad libitum in order to prevent this risk of dehydration.
