Here are estimates from MRC Centre for Global Infectious Disease Analysis at Imperial College: => Estimated fatality ratio for infections 1% (including those who don't go to see doctors) => Estimated Case Fatality Rate (CFR) for travellers outside mainland China (mix severe & milder cases) 1%-5% => Estimated CFR for detected cases in Hubei (severe cases) 18% The last line (18%) applies when the outbreak becomes prevalent in an area and overwhelm hospital capacity. If not contained, dozens of cities around the world may become Hubei! Ref: Report 4 here: https://www.imperial.ac.uk/mrc-global-infectious-disease-ana.. https://www.imperial.ac.uk/mrc-global-infectious-disease-ana.... From Report 6: "we estimated that about two thirds of COVID-19 cases exported from mainland China have remained undetected worldwide, potentially resulting in multiple chains of as yet undetected human-to-human transmission outside mainland China."
