Allergy Count

The most recent count for pollen and spores are listed to the right.

The allergen counts are supplied by allergist Dr. Joseph Leija, who goes to the roof of a building on the Gottlieb Memorial Hospital campus every weekday morning during allergy season (April to October) to gather pollen samples. Pollen grains and mold spores are collected from a cubic meter sample of air and counted under a microscope.
