Gastrointestinal microbiome and coronavirus disease: evidence of a bidirectional association

Abstract

The gastrointestinal (GI) microbiome remains an emerging topic of study and the characterization and impact on human health and disease continue to be an area of great interest. Similarly, the coronavirus disease 2019 (COVID-19) pandemic has significantly impacted the healthcare system with active disease, lasting effects, and complications with the full impact yet to be determined. The most current evidence of the interaction between COVID-19 and the GI microbiome is reviewed, with a focus on key mediators and the microbiome changes associated with acute disease and post-acute COVID-19 syndrome (PACS).
