That is late enough in the timeline, and the testing at that time was so insufficient, that it's really hard to say.
I don't recall losing my sense of smell, but I have been struggling more with concentration issues and depression since then. Of course, that could also be due to all the stress over losing a friend to COVID, the lockdown, the political situation in the US, etc.
The biggest disappointment for me in the whole COVID response has been the complete failure of ramping up COVID testing and doing random testing or testing of those who hadn't traveled to China.
