Description
Cali Loblundo and co-authors measured how often voice box problems follow a COVID-19 infection, in a 2026 study. Using a global electronic health record network of over one hundred and eighty million patients, the team matched adults who had COVID with similar uninfected controls, none with prior laryngeal trouble. They tracked chronic cough, swallowing difficulty, voice disorders, vocal fold paralysis, and laryngeal spasm for up to five years.
Every outcome was significantly more common after COVID. Odds peaked at about sevenfold for chronic cough and roughly threefold for swallowing problems and voice disorders, though absolute risk differences stayed small. Most outcomes peaked one to two years after infection, spasm later. Hospitalization and ventilator use raised several risks sharply. The authors conclude that new laryngeal dysfunction is a real, delayed part of long COVID that clinicians should watch for.
