COVID-19 Outbreak Information Updates (Reboot) [over 150.000,000 US cases (est.), 6,422,520 US hospitilizations, 1,148,691 US deaths.]
My brother had this after he got it last February. When his sense of taste and smell came back, it came back all screwed up and things tasted and smelled horrible. He stopped drinking coffee completely because of it. He likened the smell/taste of a number of things to rotten onions.
It's been close to a year, but he's finally mostly returned to normal.
