Reports from the Medical Research Council's Centre for Global Infectious Disease Analysis at Imperial College, London have been providing mathematically calculated estimates of cases and case fatality rates. In February 2020, the team at Imperial College, led by epidemiologist Neil Ferguson, estimated about two-thirds of cases in travellers from China were not detected and that some of these may have begun "chains of transmission within the countries they entered". They forecast that the new type of coronavirus could infect up to 60% of the UK's population, in the worst-case scenario.
