| Upper airway symptoms | Chest symptoms | Somatic symptoms | |
|---|---|---|---|
| *Moderate or severe symptoms in previous week, defined as: upper airway: two or more of: irritated nose, throat, voice, or taste disturbances; chest: two or more of: cough, wheezing, chest tightness, breathlessness; somatic: two or more of: fever, headache, dizziness, tiredness, nausea. | |||
