According to a study in JACC: Heart Failure, which is the first of its kind to find a link between long-haul COVID-19 and chronic fatigue syndrome, many long-haul COVID-19 patients experience chronic tiredness syndrome and other breathing difficulties months after their initial COVID-19 diagnosis.
Chronic tiredness syndrome is a medical condition that develops after a viral infection and causes fever, muscular pain, and extreme tiredness. Many COVID-19 patients who were never hospitalized have reported persistent symptoms following their first COVID-19 diagnosis. Patients who have PASC (Post-Acute Sequelae of SARS-CoV-2 Infection) are termed “long-haulers.”
