"I remind patients that allergies can exacerbate existing lung conditions. Where it's difficult is when people have asthma, because there's a component of shortness of breath and chest tightness too. One of the things I tell patients is that you know yourself the best. If you typically feel a certain way in the springtime, or when you have allergy-related asthma exacerbation, that is probably what you have. If you have unusual symptoms, or something outside of the norm, that's when people should be concerned. The thing to remember is that COVID-19 has a very particular clinical profile: fever, sometimes a high grade one, and a dry cough. Some have reported a loss of taste or smell."
