Here is the link to the report itself - <a href="https://www.imperial.ac.uk/media/imperial-college/medicine/sph/ide/gida-fellowships/Imperial-College-COVID19-NPI-modelling-16-03-2020.pdf" rel="nofollow">https://www.imperial.ac.uk/media/imperial-college/medicine/s...</a><p><a href="https://www.imperial.ac.uk/mrc-global-infectious-disease-analysis/news--wuhan-coronavirus/" rel="nofollow">https://www.imperial.ac.uk/mrc-global-infectious-disease-ana...</a><p>The report is published on March 16th.
