The analysis suggests subjective measures underestimate the true extent of scent loss and that it could be an efficient device for diagnosing COVID-19 early, the authors stated in a Monell information launch.
For the examine, the researchers reviewed beforehand printed research on COVID-19 and lack of scent.
