Which symptom combination is typical of COVID-19?

• A. Cough, fever, chest pain, and anosmia (loss of smell)
• B. Cough, runny/stuffy nose, and sore throat
• C. Barrel chest, pursed-lip breathing, cyanosis, and dyspnea on exertion
• D. High fever, drooling, stridor, and tripod position in a child

Answer: (A)

Recognizing a symptom pattern most characteristic of COVID-19. Cough and fever are common in many respiratory infections, but the addition of anosmia (loss of smell) is especially telling for COVID-19, making this combination more specific than others. Chest pain can occur with COVID-19 as the illness progresses, but the presence of anosmia alongside cough and fever helps differentiate it from other illnesses.

The other symptom groupings point to different conditions: a milder upper respiratory pattern with runny nose and sore throat fits many colds rather than COVID-19; signs like barrel chest, pursed-lip breathing, cyanosis, and dyspnea on exertion suggest chronic lung disease or acute respiratory distress rather than COVID-19; and a child with high fever, drooling, stridor, and a tripod position would raise concern for an acute airway obstruction such as epiglottitis or croup.

So the combination including anosmia is the best match for COVID-19.
