My best friend’s two college age sons got vivid about 6 weeks ago. She sequestered them in the in law suite in the basement. Left their food by the door. They had the equivalent of mild head colds and lost sense of smell and taste. 3 days later they were fine. Took awhile to get back smell and taste. She and her husband never caught it.
It’s been almost two months for me, and I still don’t feel like my sense of smell is 100%.
