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.

Whole Genome Sequencing Versus Whole Exome Sequencing for Congenital Diarrhea and Enteropahty

This study will seek to determine if whole genome sequencing (WGS) improves diagnostic rates, and outcomes for congenital diarrhea and enteropathy (CODE) patients. The investigator will enroll 180 patients in a randomized controlled study to either WGS or whole exome sequencing (WES). This study is designed to evaluate whether CODE patients would benefit from WGS guided precision medicine.

Coupons for Safe Water Project

Guaranteeing access to safe drinking water is still a challenge in rural households in developing countries, and unsafe water sources are responsible for millions of deaths each year around the world. Coupons for free dilute chlorine solution are a cost-effective and effective way of ameliorating child health and reducing diarrhea incidence. It is still an empirical challenge, however, to see if the positive health effects will be maintained when the program is implemented at scale. In this study, investigators conduct a randomized controlled trial (RCT) at scale to study the impacts of a chlorine coupon program implemented at health clinics on child health, including self-reported diarrhea, fever, and cough incidence in the previous two weeks. Investigators further investigate the pathway of the impact, such as self-reported and objectively measured use of chlorine and frequency of visits to health clinics.
