The Influenza Containment-United States and Great Britain project examined whether pandemic flu could be mitigated in the United States, assuming containment in SE Asia failed. This project was developed in collaboration with the DHHS and consisted of three studies: the Imperial Assessment study, the Epicast assessment, and the EpiSims assessment. The Imperial Assessment study consisted of two models: one describing disease transmission in the United States and the second describing transmission in GB. The GB model served as a counterpoint for the United States model, suggesting some interesting influences of geography and national patterns of behavior on disease spread.
