The Flu as an Epidemiological Model

The 1918-1919 outbreak has continued to intrigue investigators at Johns Hopkins and elsewhere. They have given the war-related outbreak new purpose: understanding and preparing for deadly flu pandemics in the present. The post-9/11 world has created anxieties about the possibility of biological warfare. Outbreaks of SARS and H1N1 have also reminded Americans that the spread of unusual strains of influenza remains a real and frightening possibility. As the biggest flu pandemic in modern history, the 1918-1919 outbreak’s numbers and movement have become useful models for thinking about potential future scenarios. In 2006, Derek Cummings and Donald Burke of the Bloomberg School of Public Health mined data from the outbreak and used computer technology to map its movement and magnitude. They were developing a tool for thinking about the potential movement of 21st-century avian flu pandemics across the globe.
