Which symptom set best matches COVID-19?

• A. Cough, fever, chest pain, and anosmia (loss of smell)
• B. Cough, runny/stuffy nose, and sore throat
• C. Fever and barking cough in a pediatric patient
• D. Coughing fits with a "whooping" sound and fever

Answer: (A)

Recognize that loss of smell (anosmia) is a distinctive feature often seen with COVID-19. When you see a symptom set that includes cough, fever, chest pain, and anosmia, the anosmia helps point toward COVID-19 because many other respiratory illnesses don’t usually cause this symptom. Fever and cough are common to many infections, but the presence of anosmia makes this combination more characteristic of COVID-19, with chest pain fitting as a possible manifestation of lung involvement or inflammation.

The other profiles align with different conditions. Runny nose and sore throat without smell loss are typical of many colds or other viral infections. A barking cough in a child is suggestive of croup, not COVID-19. A paroxysmal coughing fit with a whoop is classic for pertussis.

So the set including cough, fever, chest pain, and anosmia best matches the symptom pattern associated with COVID-19.
