DENVER (KDVR) — Fall is officially here and with it, comes seasonal allergies. From coughing, to sneezing, and even that scratchy throat, how can you tell the difference between your allergies and COVID-19?

The answer might not be as simple as it seems. The easiest way to determine the difference is by getting a COVID-19 test.

According to National Jewish Health Allergist, Flavia Hoyte, MD, “Most people who have allergies know what their allergies feel like and when they tend to peak.”

Another good way to know the difference is that a fever does not accompany allergies. However, you can be sick with COVID-19 and not have a fever.

Here’s a look at symptoms of both COVID-19 and allergies.

Symptoms of allergies

These are the common symptoms of allergies, according to National Jewish Health:

  • Itchy, watery and/or red eyes
  • Nasal congestion
  • Runny nose
  • Postnasal drip
  • Sneezing
  • Itching of the skin

Some allergy symptoms, like nasal congestion or runny nose, also can be symptoms of viral infections such as a cold or COVID-19.

Allergies generally will not affect the lungs, but can trigger asthma in people with allergic asthma. Allergies also typically do not cause a fever or extreme fatigue, according to the National Jewish Health.
