The City of Louisville Diarrhea (CLOUD) study was created in partnership with Pfizer to determine the diarrhea burden in adults in the United States attributable to Clostridioides difficile infection (CDI). Led by Dr. Julio Ramirez, Chief of Infectious Diseases at the University of Louisville, the CLOUD study is an ongoing, international study designed to generate consistent and comparable population-based incidence in the inpatient setting.
