It seems during conversations with people recently that it’s hard to get a handle on what some of these numbers actually look like. A small bump in an input parameter from say, 0.1% to 0.2% is actually a significant number of people. So I’ve created a little back of a napkin calculator.
The first two text boxes let you plug in two numbers and get a percentage out. In this case the gross number of infections and the number of deaths. Hit the calculate button and out pops the mortality rate. The two numbers this starts with are the two metrics for the UK as of 9th May. (Sourced from Google)
The second lot of controls (the slider and the list of percentages), show what those various mortality rates would look like based on the number of infections as controlled by the slider. The percentage shown in red, is using the calculated mortality rate from the first calculation.
