Gut microbiota could predict severity of COVID-19

The COVID-19 pandemic is spreading to every corner of the world. But not everyone is falling sick at the same rate. A new study published on the preprint server medRxiv in April 2020 suggests that the composition of the gut microbiome could partially explain the difference in susceptibility. This adds a new dimension to what is currently known about the disease.
