Clade X: A Global Health Security Simulation was a pandemic modelling exercise led by Johns Hopkins University's Center for Health Security, which occurred on Tuesday, May 15, 2018, at the Mandarin Oriental Hotel in Washington, D.C. [1] The exercise was named after a hypothetical novel virus, and simulated efforts to counter a fast-moving and deadly epidemic released on purpose by a terrorist group consisting of scientists and their rich backers wanting to reduce overpopulation. [2] [3] In the simulation, the hypothetical pandemic resulted in 900 million simulated deaths. [4] The exercise was invitation-only and nearly 150 people attended. [5]
The exercise was co-hosted by the Program for Appropriate Technology in Health (PATH), the Global Health Council, and the Nuclear Threat Initiative (NTI). [6] It was funded through a grant from Open Philanthropy. [7]
