| Summary/Abstract |
Global public health has struggled to provide timely warning of influenza pandemics. In this study, we review the signal pattern of local media reporting associated with the 1918 type A/H1N1 influenza pandemic and subsequent return of the A/H1N1 virus in 1977 and 1978 in Philadelphia. Open source local media reports are a critical source of warning intelligence for influenza pandemics. Documentation and analysis of pandemic influenza signal patterns is essential to capture lessons in effective warning intelligence for health security.
