Diarrhea, Infantile

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.

This study will establish a clinical cohort of children with congenital diarrhea and enteropathy (CODE), mine biomarkers of CODE through multi-omics technology and construct a clinical risk prediction model.

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.
