My wife and I both caught COVID in early 2020. We both lost our sense of smell when we first caught it. Mine came back within a week. My wife’s never did.
I now have it again, so far my wife does not. This time my sense of smell doesn’t seem to be affected.
I’ve heard that Omicron does not cause loss of taste and smell. That may be what you have. Also heard 95% of new cases are Omicron.
