I had COVID in August. Didn't really lose sense of smell, but my sinuses were so stopped up, I was probably not at 100%. Really bad cold for me, wife actually had it worse, with even a fever.
BTW, tests were useless. I had symptoms of cold, then next day she did. I took test negative, 2 days later she was positive, 2 days later, I was negative, 2 days later, she was still positive. Pretty similar symptoms.
I have the more sensitive nose for dangers (natural gas, electrical fire, etc.) while wife is more sensitive to aromas, etc.
I did think I had an issue on last camping trip when I couldn't smell the propane, but turned out my tank was empty and I needed to open the other valve...
