Scientists find key reason for ongoing loss of smell in long-COVID

In a recent study published in the journal Science Translational Medicine, researchers reported that long-term anosmia following coronavirus disease 2019 (COVID-19) could be a result of persistent T-cell mediated inflammation occurring in the olfactory epithelium even after the elimination of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) from the olfactory tissue.
