Journal ArticleDOI
Strategies for mitigating an influenza pandemic
Neil M. Ferguson,Derek A. T. Cummings,Christophe Fraser,James Cajka,Philip C. Cooley,Donald S. Burke +5 more
TL;DR: It is found that border restrictions and/or internal travel restrictions are unlikely to delay spread by more than 2–3 weeks unless more than 99% effective, and vaccine stockpiled in advance of a pandemic could significantly reduce attack rates even if of low efficacy.
ReportDOI
Synthesized Population Databases: A US Geospatial Database for Agent-Based Models.
William D. Wheaton,James Cajka,Bernadette Chasteen,Diane Wagener,Philip C. Cooley,Laxminarayana Ganapathi,Douglas J. Roberts,Justine Allpress +7 more
TL;DR: The methods used to generate the synthesized population database and the final data structure and data content of the database are described to provide researchers with the information they need to use the database in developing agent-based models.
Journal ArticleDOI
The Role of Subway Travel in an Influenza Epidemic: A New York City Simulation
Philip C. Cooley,Shawn T. Brown,James Cajka,Bernadette Chasteen,Laxminarayana Ganapathi,John J. Grefenstette,Craig R. Hollingsworth,Bruce Y. Lee,Burton Levine,William D. Wheaton,Diane Wagener +10 more
TL;DR: An agent-based model computer simulation of New York City’s five boroughs was developed that incorporated subway ridership into a Susceptible–Exposed–Infected–Recovered disease model framework, estimating that if influenza did occur in NYC with the characteristics of the 1957–1958 pandemic, 4% of transmissions would occur on the subway.
Journal ArticleDOI
Protecting health care workers: a pandemic simulation based on Allegheny County
Philip C. Cooley,Bruce Y. Lee,Shawn T. Brown,James Cajka,Bernadette Chasteen,Laxminarayana Ganapathi,James H. Stark,William D. Wheaton,Diane K. Wagener,Donald S. Burke +9 more
TL;DR: Protecting health care workers: a pandemic simulation based on Allegheny County and Influenza and Other Respiratory Viruses 4(2), 61–72 is cited.
Journal ArticleDOI
What is Threatening Forests in Protected Areas? A Global Assessment of Deforestation in Protected Areas, 2001-2018.
Christopher M. Wade,Kemen Austin,James Cajka,Daniel Lapidus,Kibri Hutchison Everett,Diana Galperin,Rachel Maynard,Aaron Sobel +7 more
TL;DR: It is found that forest loss in PAs is most commonly—and increasingly—followed by shrubland, a broad category that could represent re-growing forest, agricultural fallows, or pasture lands in some regional contexts.
