Alpha-beta diversity of microbiota in the gut and oral wash of healthy controls and COVID-19 cases. (A–F) α-Diversity measurements of the gut and oral microbiota in terms of observed operational taxonomic units, Shannon, and Simpson index, respectively. (G) Unweighted (presence-absence) and (H) weighted (relative abundance) UniFrac metric for the gut and oral microbiota of healthy control and COVID-19 cases. (I) Unweighted and (J) weighted UniFrac metric for the gut microbiota of healthy control and COVID-19 cases. (K) Unweighted and (L) weighted UniFrac metric for the oral microbiota of healthy control and COVID-19 cases. #Significantly different at alpha-level of 0.05. ##Significantly different at alpha-level of 0.005. ###Significantly different at alpha-level of 0.001. **Significantly different at alpha-level of 0.005. ***Significantly different at alpha-level of 0.001.
