Allergy, cold, flu, asthma, RSV or COVID-19?

It can be difficult to distinguish the symptoms of COVID-19 from those of a cold, the flu (influenza), or even from asthma, seasonal allergies, and respiratory syncytial virus (RSV).

To get an understanding of the differences, consult the following chart (source: Asthma and Allergy Foundation of America [1]), which outlines the symptoms of each condition.

Keep in mind that these are only the most common symptoms. Their severity and intensity can vary greatly from person to person, and other symptoms may appear. In addition, allergies, a cold or the flu can lead to asthma attacks. When in doubt, or if your health is a concern or deteriorating, consult a doctor.
