Candidate, Pardee RAND Graduate School, A New Tool Helps Analyze Commercial Air Travel Involving Infected Passengers, by Russell Hanson, Christopher A. Mouton, Adam R. Grissom, John P. Godges. Together, these data sets make it possible to visualize how COVID-19 infections and commercial air travel have interacted to export infection risk across the world.

This limitation is particularly relevant if the travel patterns of air travelers from Hubei were different from the patterns of air travelers from China more broadly. The RAND Corporation is a research organization that develops solutions to public policy challenges to help make communities throughout the world safer and more secure, healthier and more prosperous.

This report and the CAT-V tool will be of interest to U.S. Department of Defense policymakers and planners at the strategic and operational levels. Traffic visualization. Together, these data sets allow the researchers to visualize and analyze the estimated transmission of the novel coronavirus via air travel, outline the resulting implications, and offer suggestions for minimizing the most-dangerous potential vectors. As of May 22, 2020: Johns Hopkins University Center for Systems Science and Engineering, "Novel Coronavirus (COVID-19) Cases," data repository, undated. Using the CAT-V tool, we estimate the global spread of COVID-19 by international air passengers prior to the March 11, 2020, declaration by the World Health Organization (WHO) that the world was officially experiencing a pandemic—defined as "the worldwide spread of a new disease." The United States, in particular, was facing importation risks from every continent except Antarctica.

However, the increase in daily exports in late February exceeded the bounds of our linear chart.

Tesla has started to roll out Software Update 2019.36.1, showing improvements to the Driving Visualization feature. The Pardee RAND Graduate School (PRGS.edu) is the largest public policy Ph.D. program in the nation and the only program based at an independent public policy research organization—the RAND Corporation. Russell Hanson is a research software engineer at the RAND Corporation. First change the url to the API's url using the variable api_url.

In reality, the number of active COVID-19 positive cases today could reflect the rate of infection up to two weeks ago. The portions of the curves shown in red highlight the convex portions, or the accelerating daily increases in COVID-19 exports. The countries with the largest numbers of likely infected inbound passengers by that date spanned Asia, North America, and Europe.

Christopher A. Mouton, Russell Hanson, et al. In particular, we estimate that the worldwide exports of COVID-19 cases began increasing at an accelerating rate on February 19, 2020, exactly three weeks before the WHO declaration.
