NCT ID NCT04153331

First seen Jun 25, 2026 · Last updated Jun 26, 2026 · Updated 1 time

Summary

This study tracked nearly 2,500 adults who came to the emergency room during flu season to see how many actually had the flu. By testing everyone with a nasal swab, researchers aimed to find flu cases that might otherwise go unnoticed. The goal is to give hospitals a clearer picture of flu's real impact on emergency services.
