Gallup: U.S. flu season lasting longer

WASHINGTON, May 6 (UPI) — The U.S. flu season started slow last fall in September, October, and November, but extended longer into spring this year, a Gallup poll indicates.
The Gallup-Healthways Well-Being Index data measures the self-reports of colds and flu from 1,000 U.S. adults daily. Measuring cold versus flu is complex because of the overlapping symptoms and many Americans’ misunderstanding what symptoms constitute “the flu” versus “a cold.” The poll provides a picture of cold and flu prevalence trends.
