NCT ID NCT06482138

First seen May 08, 2026 · Last updated May 08, 2026

Summary

This study aims to understand why some people lose their sense of smell after a COVID-19 infection and why it doesn't come back. Researchers will collect tiny samples of tissue from inside the nose of 240 people—some with smell problems and some without. By comparing these samples under a microscope, they hope to find clues about what goes wrong in the nose after the virus.
