COVID-19 is caused by a virus and therefore contagious, whereas allergies are caused by an excessive immune response to a triggering allergen. However, COVID-19 symptoms are often similar to symptoms of seasonal allergies, so it is important to know how to tell the difference. 

If you are unsure whether your symptoms indicate a COVID-19 infection or allergies, however, it is best to get tested just in case to ensure that you receive timely treatment and avoid spreading the disease.

COVID-19 vs. allergy symptoms: chart

Allergies cause persistent symptoms, such as sneezing and wheezing, that can linger for several weeks. COVID-19 causes symptoms such as fever, body aches, and coughing, which are uncommon in seasonal allergies.

How to distinguish between COVID-19 and allergies

COVID-19 can be contracted in addition to seasonal allergies. If your typical seasonal allergy symptoms seem to be much worse this year or you are having any new or unusual symptoms, you should contact your doctor. They may advise you to get tested for COVID-19. 

The following may help you understand what is causing your symptoms:

• Symptoms: 
  • Both allergies and COVID-19 can cause coughing and loss of taste and smell. However, allergies can cause an itchy nose, eyes, and ears, which are unusual COVID-19 symptoms.
  • COVID-19 can cause flu-like symptoms, such as body pains, chills and fever, which are not usually linked with allergies.
• Medical history: 
  • Your medical history can help you figure out what is causing your symptoms. You may be suffering from allergies if you: 
    • Have had seasonal allergies previously, and your present symptoms are similar to those you have had in the past.
    • Have had an allergy test and discovered that you are allergic to ragweed, mold, pollen or another airborne allergen.
    • Recently relocated to a new area with high seasonal pollen concentrations.
• Tests: 
  • If you do not have a history of allergies or are experiencing symptoms that are not consistent with allergies, you should be tested for COVID-19. 
  • If your COVID-19 test results are negative and you still do not know what is causing your sniffling and sneezing, you may consider being tested for seasonal allergies.

What are prevention strategies for COVID-19 and allergies?

Protecting yourself from COVID-19
