Influenza researchers at five sites in the United States received funds from the American National Institute of Allergy and Infectious Diseases (NIAID) to collaborate with scientists worldwide in a network designed to advance understanding of influenza viruses – especially how they cause disease. The centers are based in Icahn School of Medicine at Mount Sinai (New York City), Emory University (Atlanta), St. Jude Children’s Research Hospital (Memphis), University of Rochester Medical Center (Rochester) and Johns Hopkins University (Baltimore).
