Infections Including SARS-CoV-2 As Triggers for Vocal Cord Dysfunction.

Vocal cord dysfunction (VCD) is a cause of acute and/or chronic respiratory symptoms. Vocal cord dysfunction, also called inducible laryngeal obstruction and paradoxical vocal fold movement, is the functional closure of vocal cords during inspiration diagnosed by direct visualization by rhinolaryngoscopy (RLG) when the patient is symptomatic, typically induced by bronchoprovocation challenges including methacholine inhalation or exercise. Vocal cord dysfunction is a common functional disorder that is often underrecognized and misdiagnosed as asthma.
