Don’t panic Urmstongran, it’s very common for people to lose their sense of smell as a result of a respiratory virus, it doesn’t necessarily mean you have Covid, it’s because your nasal passage is inflamed, and should disappear as you get better. I know three families in different parts of the UK who have the evil non Covid respiratory virus at the moment, including my own children, both of whom have been quite poorly with it, my daughter for over a week so far. They have had negative LF and PCR tests, and were told there are lots of respiratory viruses around at the moment.
