In Italy, the proportion of infected people dying from the novel coronavirus — 10 percent according to the latest figures — seems through the roof. Unsurprisingly, there is more to this terrifying figure than meets the eye. You do not need to be an expert to calculate the mortality rate. It is one number divided by another — the number of people who have died from the virus divided by the total number of confirmed cases. In the case of Italy, 7,503 dead divided by 74,386 infected gives a mortality rate of roughly 10 percent. But that does not mean that one in ten people who contract the virus will die, despite what the scaremongering media would have you believe. The first reason why is that the first, smaller number — the number of deaths from Covid-19 — is impossible to underestimate. People are either alive or dead, and usually as soon as a person dies they will quickly find their way into the national statistics.
