- South Korean study reviewed pre-existing research on role of gut microbiome
- Hong Kong-based scientists examined blood and stool samples from patients
- Both studies indicate a gut microbe imbalance is key in severe Covid-19
The study concludes the gut microbiome may be involved in the ‘magnitude of Covid-19 severity possibly via modulating host immune responses’.
The authors found that patients with Covid-19 had depleted levels of several gut bacteria known to modify a person’s immune response.
