The Asthma and Allergy Foundation of America (AAFA) has announced the 2011 Fall Allergy Capitals rankings, and this season Knoxville, Tennessee, was rated the No. 1 Fall Allergy Capital due to high pollen counts, high use of allergy medications by patients and too few allergists to treat the burgeoning allergy population. Top 5 Fall Allergy Capitals for 2011:
| 1. Knoxville, TN | 4. Jackson, MS |
| 2. Dayton, OH | 5. Oklahoma City, OK |
| 3. McAllen, TX |
