MAYWOOD, IL – As spring arrives in the Chicago area, Loyola Medicine’s trusted daily allergy count is returning to help residents manage seasonal allergies. The official Loyola Medicine Allergy Count, compiled at Gottlieb Memorial Hospital, resumes Tuesday, April 1, providing weekday updates throughout allergy season.

For more than 20 years, Loyola Medicine has delivered one of the region’s most reliable pollen counts, offering timely data on tree, grass, weed pollen and mold levels. Allergy sufferers can access the latest counts by following @LoyolaAllergy on X or Threads.

“Seasonal allergies can cause much more than sneezing and congestion,” said Rachna Shah, MD, lead of the Loyola Medicine Allergy Count. “High pollen levels may also trigger coughing, wheezing and shortness of breath, especially for people with asthma. With the recent unpredictable weather, pollen counts are going to be even more important to help allergy sufferers take preventive steps and reduce symptoms.”

How the Loyola Medicine Allergy Count works

The allergy count is conducted every weekday morning using air samples collected from the roof of Gottlieb Memorial Hospital. A cubic meter of air is analyzed under a microscope to identify and count pollen grains and mold spores. Daily reports include specific counts for tree, grass, weed pollens and mold, helping patients and clinicians make informed decisions.

Dr. Shah explains the process in detail in this video, which also highlights the importance of accurate and consistent pollen monitoring.

What to expect during allergy season

In the Chicago area, allergy season typically runs from March through the end of September: 

• Tree pollen: late March through April
• Grass pollen: May and June
• Weed pollen: July and August
• Ragweed: late August through the first frost
• Mold: present throughout the season, especially during damp conditions
