Study finds association between long COVID symptoms and altered oral microbiome

Research by John P. Haran, MD, Ph.D., and Evan S. Bradley, MD, Ph.D., at UMass Chan Medical School, shows that patients with persistent long COVID symptoms have oral microbiomes with a significantly higher abundance of bacteria that induce inflammation. These findings suggest an association between the oral microbiome and long COVID that may point to dysfunction in the oral microbiome as a contributor to long COVID.
