Scientists find key reason why loss of smell occurs in long COVID-19 #shorts #covid19

Scientists from Duke Health have identified a key reason behind the loss of smell in long COVID-19 cases. They found that an ongoing immune attack on olfactory nerve cells and a decline in their number contribute to the inability to regain the sense of smell. This insight sheds light on other long COVID-19 symptoms and their possible underlying causes. The study's findings suggest an autoimmune-like process in the nose, and researchers are now working on developing treatments to restore smell.
