A National Allergy Bureau certified counter in Louisville, Kentucky performed daily pollen and spore counts.The mean daily pollen/spore count was determined and graphs were generated indicating the onset, peak, and duration of total tree, grass, and weed pollen and mold spores.These graphs were compared to the number of monthly new office visits in a large Allergy-Immunology practice.In addition, the pollen counts were compared to the monthly emergency room visits and admissions for asthma in a large children's hospital.
