Reviewed by Louise Chang, MD

April 19, 2006 -- Spring is prime time for allergies, and certain U.S. cities are harder hit than others, according to the Asthma and Allergy Foundation of America (AAFA).

Every year, the AAFA lists the 10 worst cities for springtime allergies. Here are the top 10 cities on this year's list, along with last year's rankings:

  1. Hartford, Conn. (last year: 49)
  2. Greenville, S.C. (last year: 6)
  3. Boston (last year: 47)
  4. Detroit (last year: 80)
  5. Orlando, Fla. (last year: 56)
  6. Knoxville, Tenn. (last year: 11)
  7. Omaha, Neb. (last year: 17)
  8. Sacramento, Calif. (last year: 62)
  9. Washington, D.C. (last year: 16)
  10. Baltimore (last year: 58)

Curious about where your city ranks? The full list can be found at the end of this story.

About the List

The top cities on last year's list were located in the Southeast. But allergies are a nationwide problem, and the rankings can change from year to year. For instance, last year's leader -- Lexington, Ky. -- is in the 75th spot on this year's list.

Rankings are based on three factors: pollen scores, the number of allergy medications used per patient, and the number of allergy specialists per patient.

Funding for the AAFA's new list came from Procter & Gamble, Schering-Plough, and

Procter & Gamble makes allergen-reducing products. Schering-Plough makes a prescription nasal spray for nasal allergy symptoms. is a division of Surveillance Data Inc., a private company that researches health care and consults for the pharmaceutical and consumer products industries.

Seeking Relief

Consult a doctor to get your allergies diagnosed and treated.

If you're allergic to pollen, close the windows at home and in your car. If you need to cool down, run the air conditioning instead of opening the windows. Put the air on "recirculate" so you're not bringing in outside air filled with pollen.

As many as 50 million people in the U.S. have allergies, and nearly 36 million of them have hay fever (a seasonal allergy to pollen), according to the American Academy of Allergy, Asthma & Immunology.
