Alterations in human intestinal microbiota in the course of SARS-CoV-2 virus infection.

There is an interaction between the bacteria and the host at the genetic, metabolic and immunological levels. The intestine is the largest immune organ in the human's body, and the microbes present in it influence the immune response. An imbalance in the type and the number of bacteria can affect human health. The study attempts to review the current reports on intestinal dysbiosis in the course of SARS-CoV-2 infection and the impact of the composition of the intestinal microbiome on the course and severity of COVID-19 disease.
