Descriptive Study of Pathogens Involved in Summer Diarrhea in Children Leading to Pediatric Emergency Room Visits (PE-DIA)

Acute diarrhea in children is a public health problem. It is estimated that children under 3 years are subject to 1 or 2 episodes of diarrhea per year in Europe. These diarrheal episodes are frequent, expensive and responsible for many consultations and hospitalizations in developed countries. The origin of diarrhea in children is viral in about 70% of cases. The diagnosis of a viral infection is often considered without microbiological evidence. However, microbiological evidence is recommended for certain categories of patients. The involvement of bacteria or parasites in the child's diarrhea does not seem negligible. The main objective of this study is to estimate the prevalence of infectious diarrhea among summer diarrhea in children leading to pediatric emergency room visits. Secondarily, we will describe the pathogens responsible for childhood diarrhea during the summer period, describe common factors that can serve as guidance on the etiology of diarrhea, and describe common factors that can be used as tools. preventive to the transmission of these pathogens.
