Global Epidemic and Mobility Modeler - H1N1 Scenario

Global Epidemic and Mobility Modeler - H1N1 Scenario

Description:

The Epidemic Planet visualization was developed within the context of the GLEaMviz project and displays the evolution of the 2009 H1N1 influenza pandemic and enables its users to learn about the epidemic spreading on the global scale as simulated here, using GLEaM, the GLobal Epidemic and Mobility modeler.

GLEaM is a computer model that takes into account human populations connected through a network of interactions by human travel fluxes corresponding to transportation infrastructures and mobility patterns. The GLEaM simulation engine includes detailed population information and a multiscale mobility model integrating different layers of transportation networks ranging from the long range airline connections (accounting for more than 99% commercial traffic worldwide) to the short range daily commuting patterns (from the statistical analysis of census data from over countries in 6 different continents).

This visualization illustrates the spread of the H1N1 influenza pandemic based on a detailed simulation performed using GLEaM that was able to predict the course of the pandemic several weeks in advance (BMC Medicine 7, 45 (2009)) and served as a way for researchers to evaluate the potential impact of several intervention measures. Starting from the first reported cases in La Puebla, Mexico on Feb 18, 2009, the course of the pandemic is followed as it spreads around the world. As passengers travel from an infected to an uninfected city, an edge is drawn connecting them so that we may follow the path taken by the virus. As new cases are generated from this passengers arrival, the city and its surrounding gradually changes color indicating the estimated number of cases, corresponding to the colorbar.
