During the height of the flu season, researchers from Georgia Tech and Emory University took four crowded flights from Atlanta to the West Coast. They observed passenger and crew movements, took air and surface samples, and listened for anyone who was coughing. The researchers were gathering data for a new study on how infectious diseases are transmitted among air travelers. School of Mathematics Professor Howard Weiss was a co-author of the study. The results of the research continue to get mainstream media attention, including this New York Times story and an article in Smithsonian Magazine.
