Long COVID or post-COVID Condition, defined as the persistence of symptoms at least three months post-acute COVID-19 infection, is a novel condition where a definitive diagnostic marker and treatment has yet to be found. This condition, which has been estimated to impact more than 65 million individuals worldwide, manifests with multisystem involvement, most commonly presenting with fatigue, brain fog, dyspnea and/or cough. The burden of these symptoms can range from mild to severe with many patients reporting an inability to return to usual activities. Here, we present several hypothetical but clinically representative cases to allow discussion around how we approach the diagnosis of respiratory symptoms of Long COVID in those with and without chronic lung disease.
