Use pulldown or enter amount in box. No letters or units (e.g. enter 0.2 not 20%). This calculator estimates deaths for an epidemic or pandemic for a population size, infection rate (e.g. 30% of the population will catch it) and CFR or Case Fatality Rate (e.g. 3% of those infected will die.) It can help pandemic planning by speeding up calculations.
CFRs are all estimates. The ultimate Case Fatality Rate for COVID-19 is unknown because the pandemic is still unfolding, but 3.8% is the current global (crude) figure (16 March 2020). For Italy, it's 7.3%.
