Science-Based Policy Analysis<\/strong><\/p>\n

Goals<\/h3>\n

The VIPRA project is an interdisciplinary multi-university effort to analyze new strategies for reducing the risk of spread of viral infections through air-travel. Our goals include disease spread during air travel and those imported through air travel. We accomplish these by integrating accurate models and new data sources with a computational infrastructure that is designed for simulation-based policy analysis on some of the most powerful\u00a0supercomputers in the world.<\/p>\n

Challenges<\/h3>\n

The VIPRA approach is based on the realization that inherent uncertainties in human behavior make it difficult to predict the consequences of any particular policy choice accurately. Instead, it is more fruitful to determine a\u00a0range of possible outcome scenarios, identify potential vulnerabilities, and evaluate the relative merits of feasible policy choices. In addition, conventional data sources do not provide the required spatial and temporal resolution. New data sources, such as social media, on the other hand, suffer from limitations such as bias and noise.<\/p>\n

Approach<\/h3>\n

VIPRA includes a fine-scale model that tracks individual passenger movement in locations with crowds, such as airplanes and airports, based on\u00a0social dynamics and empirically observed\u00a0passenger\u00a0behavioral characteristics. Sources of uncertainty are parameterized, and simulations performed to cover the range of possibilities. Results from individual flights are linked with genetic information in a\u00a0phylogeographic model to evaluate the likelihood of epidemics and to identify pathways for the spread of diseases. We incorporate results from novel data sources, such as social media data, into our models, to improve spatial and temporal resolution while accounting for demographic heterogeneity. Our analysis is validated with empirical data to ensure that the guidance offered by us is likely to be realistic.<\/p>\n

The massive computational demand of such analysis is met through computational allocations on some of the world’s most powerful supercomputers. Our models will be integrated into a software infrastructure targeted for decision support\u00a0so that decision-makers can effectively evaluate “what-if” scenarios.<\/p>\n

Outcomes<\/h3>\n

The above techniques will help achieve VIPRA’s goal of\u00a0deploying a comprehensive and accurate decision-support infrastructure\u00a0that can be used to eliminate the threat of any new outbreak of an epidemic.<\/p>\n
