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

After obtaining consent from the holders of parental authority, a stool collection will be requested from all pediatric emergency patients presenting as a reason for "diarrhea" consultations between June 1 and September 30, 2020. It will be given by the nurse organizing the reception, a medical information questionnaire and a stool collection container for those accompanying a child with diarrhea. If the child presents stool during the waiting period or during the medical consultation, these will be collected and sent to the medical biology laboratory of the University Hospital for a broad analysis (virological, bacteriological and parasitological). The doctor in charge of the patient will complete a pre-established clinical information sheet. In the laboratory, the stool will be taken care of and a DNA extract will be made and preserved. The search for pathogens will be carried out by molecular biology, by series, non-prospectively. The results will only be transmitted at a distance and will not be communicated to families. Therapeutic management of children included in the study will be identical to the usual practice. Microbiological analysis will not delay, prolong or disrupt the treatment of the acute episod of diarrhea.
