How Covid-19 smell loss differs from the common cold

(University of East Anglia) New research is the first to compare how Covid-19 smell loss differs from what you might experience with a bad cold or flu.The main differences found are that Covid-19 patients can breathe freely, do not tend to have a runny or blocked nose, and they cannot detect bitter or sweet tastes.These findings lend weight to the theory that Covid-19 infects the brain and central nervous system.
