My wife didn’t have any underlying condition. We all got Covid in November 2020, and she has still not fully recovered. They say that some people lost their sense of smell for a while. She didn’t lose her sense of smell, it’s that her brain got rewired so that nothing smelled right anymore. Citrus like lemons and grapefruit, smelled like burning sulfur to her. Peanut butter was one of her favorite foods, now she cannot stand the taste or the smell. It makes her nauseous. Many examples.
