Gut microbiome linked to SARS-CoV-2 infection and COVID-19 severity

The gut microbiota impacts human health and contributes to regulate immune responses. Severe COVID-19 illness is characterized by a pro-inflammatory immune response. The effect of SARS-CoV-2 on altering the gut microbiome and the relevance of the gut microbiome on COVID-19 severity is unclear. This study analyses the gut microbiome associated with SARS-CoV-2 infection and COVID-19 severity.
