Achoo! Blame pollen and mold

By Marie McCullough

Inquirer Staff Writer

As if having record-breaking, August-style heat and humidity in April isn't

uncomfortable enough, the weather is pushing tree pollen and mold counts to

unprecedented levels.

For people with both asthma and allergies, this heat spell has been not just

unpleasant, but risky, pulmonary specialists say. In the worst scenario, a

person with diagnosed allergies but undiagnosed asthma could suffer a

life-threatening asthma attack triggered by pollen and outdoor exertion,

said Gilbert D'Alonzo, a pulmonary specialist and asthma researcher at

Temple University Hospital.

D'Alonzo said his regular patients, too, are miserable - as is he: " I have

allergic rhinitis myself, and personally, this has been one tough spring. "

Schools, meanwhile, are dealing with an epidemic of sneezing, sniffling and

coughing.

" Tuesday, Wednesday and Thursday have been the worst days this year, " said

Amy Hawthorne, the nurse at Cherry Hill's Knight Elementary School.

" I've had a steady stream of customers with red, swollen eyes. I rinse their

eyes, then give them packs of ice. "

Yesterday, the tree-pollen count was 2,886 - that's how many tiny,

irritating grains passed through a cubic meter (a refrigerator-sized area)

over a 24-hour period.

Anything over 300 is high, and enough to aggravate seasonal allergies, said

Dvorin, an allergist who has taken daily pollen readings for a decade

for the National Allergy Bureau, part of the American Academy of Allergy,

Asthma and Immunology. In fact, yesterday's count was six times higher than

the highest Dvorin had previously recorded on that date.

Adding to the sylvan haze, the mold-spore count - which usually stays low

until the humidity of late summer and fall - was 3,481, more than three

times the level defined as " high. "

And thanks to the drought, there has been precious little rain to wash the

atmosphere free of pollen, the tiny granules that are produced to fertilize

other trees.

It's no surprise that people with asthma, allergies, or respiratory problems

(and, to a lesser degree, anyone who breathes) have been miserable.

Dvorin, who sees patients at the Asthma Center in Mount Laurel, has been

unusually busy.

" The tree-pollen peak seems to be one to two weeks earlier this year than

usual, " he said. " The heat and humidity really drive the pollen counts up. "

Last year, for reasons no one could explain, trees went into a reproductive

frenzy, with the pollen count reaching a staggering 6,800 in the first week

of May.

Does that suggest that in a few weeks, counts will go even higher, making

the air as thick as the green film now coating windshields?

" It's a good question, " Dvorin said. " I would not expect it to peak much

higher than it is now. There's a limit to the amount of pollen trees can

produce. "

Up to 20 percent of the population is bothered by at least one seasonal

allergen - tree, grass or ragweed pollen. Dvorin estimates two-thirds of

those sufferers are tree-sensitive.

D'Alonzo said sufferers with severe breathing problems should not rely on

over-the-counter medicines.

" This is a problem. Asthma is still being misdiagnosed, " he said. " You get a

person who, in the past, could take a cold medication or allergy medication

and control allergy symptoms. But now, they might actually need inhaler

therapy or rescue medication " to control asthma.

Besides taking allergy or asthma medications, the experts say, the best way

to find relief is to stay in air-conditioning. It cuts indoor pollen levels

by 95 percent, and kills mold spores.
