Add to Preferred Sources Credit: Pixabay/CC0 Public Domain People with long COVID have distinct differences in the mix of bacteria that live in their mouths and lungs, according to a study of more than 700 people published in the European Respiratory Journal . The research also shows that these differences in the lung microbiome are linked to respiratory symptoms, as well as the cognitive and digestive problems known to occur in long COVID.
Researchers say their findings may shed light on why some people develop long COVID and could point to new ways to treat the condition.
