A Study to Explore the Role of Gut Flora in COVID-19 Infection

This study examines the relationship between the gut microbiome — the community of bacteria living in your intestines — and COVID-19 infection. Emerging evidence suggested that COVID-19 severity might be influenced by gut flora composition, and this study aims to document how infection changes the microbiome and whether those changes correlate with disease outcomes. Participants provide stool samples for microbiome analysis at multiple time points around the time of their COVID-19 infection. This is an observational study — no treatments are given — but findings could inform future treatments targeting the gut.
