Pos-COVID-19 syndrome: we only know how little we know

Patients who underwent COVID-19 can develop persisting symptoms and sequelae. Severe cases may exhibit systemic complications of critical care and/or inflammatory/fibrotic lung injury. Imaging and respiratory function tests can assist in the evaluation of both. Nonsevere cases can also develop persisting symptoms for more than 28 days, which has been defined as the post COVID-19 syndrome. The most common symptoms in said syndrome are fatigue, headache and dyspnea, which can last for months. Its course can be oscillating or even increase progressively within the first months. The considerable range of symptoms requires proper patient assessment. Post-infectious immune disregulation is believed to be the source of this syndrome. Proper assessment and followup warrant measured symptom management and emphatic care by the attending physician. (AU)
