Experts say that this year's allergy season will be troublesome because pollen levels are extremely high. And many people may mistake common allergy symptoms to those of COVID-19, causing undue anxiety.

The Public Health Agency of Canada says that coughs, fever, and difficulty breathing are the most common symptoms of the coronavirus. Symptoms can also include sore throat, fatigue, headache, chills, and decreased sense of smell, among others. Many of these symptoms can also signal seasonal allergies, according to City News Vancouver.

Pharmacist Gianni Del Negro said that things like "fevers, chills, cough, muscle aches, and fatigue are more specific to the flu or COVID. Itchy, running eyes and nose are more common with allergy symptoms."

He added that allergy symptoms tend to be milder, but for some individuals, they can be debilitating. If you experience shortness of breath or difficulty breathing, always consult with a healthcare professional, he told City News.

Asthma and allergy specialist Dr. Alex Thomas told ABC7 Chicago that the main difference between seasonal allergies, allergies in general, and COVID-19 are the symptoms of fevers and body aches.

"Fever is something you would really only see with a viral infection such as COVID-19," he said. "Even though we used the term 'hay fever,' you would not get a fever with environmental allergies."

Asthma sufferers need to be cautious if they develop unusual symptoms.

"Asthma is a chronic lung disease and that also increases the risk of severe complications with COVID-19," said Thomas.

"Specifically, with asthma, if a patient is needing their rescue inhaler more than two or three times a week for acute symptoms, that is a red flag."
