The U.S. is in the midst of a stronger-than-usual spring allergy season, likely spurred by the unseasonably warm winter. More Americans report being sick with allergies on any given day so far this April (22.8%) than in April 2011 (20.8%) and April 2010 (21.8%), and even during the peak of allergy season last year, when 22.1% reported allergies in May.
The 19.6% of Americans who reported allergies in March this year is closer to the rate usually seen in April and May of past years, suggesting allergy season arrived earlier than usual.
