NPR: A Warm Winter Helped Fuel West Nile Outbreak In Dallas

Dr. Robert Haley, director of epidemiology at the University of Texas Southwestern Medical Center, and senior author on a study of the outbreak said "Everybody thought it was gone. Even CDC was saying, well, I guess we can move on and do something else." But by looking closely at the Dallas outbreak, Haley and other scientists say they've found the clues they need to solve the mystery — and perhaps save lives in the next outbreak. "This gives us a new tool for determining in what year we're going to have a big epidemic of West Nile," Haley told Shots. The results were published in JAMA, a journal of the American Medical Association.
