Summary

This study aimed to understand why some COVID-19 patients lose their sense of smell. Researchers compared cells from the noses of 26 people—some with COVID-19 and some without—to look for differences in smell-related cells and immune responses. The goal was to uncover the biological causes of smell loss, not to test a treatment.
