Summary

This study looked at how COVID-19 infection relates to tinnitus (ringing in the ears). Researchers in Brazil followed 233 people who had COVID-19 between 2020 and 2024, comparing those who developed new tinnitus, those who had it before, and those without it. The goal was to understand how common post-COVID tinnitus is and how it changes over time.
