Doctors say the misery stretches from Mississippi to Ohio and from Georgia to Texas, where a drought has exacerbated the problem. Forecasters and allergists blame the unseasonably warm weather, and few cold snaps, for causing plants to bloom weeks earlier than normal and release the allergy-causing particles.
In some areas, allergists say pollen counts this week are as high as they've ever recorded. A clinic at Vanderbilt University in Nashville recorded 11,000 grains of pollen per cubic meter Tuesday, the worst in the 12 years they've tracked the number. The Atlanta Allergy & Asthma Clinic says this week's pollen counts have beaten a high mark recorded there in April 1999. Their count for Tuesday was almost 9,400. Fifteen-hundred is considered very high.
