Summary

This study looked at whether weakness in the diaphragm, a key breathing muscle, causes ongoing shortness of breath and fatigue in people who had COVID-19 but were not hospitalized. Researchers measured breathing muscle strength and used ultrasound to check diaphragm function in 25 participants. The goal was to better understand why some people still feel breathless after a mild COVID-19 infection.
