Modelling

The graph below indicates trends on a logarithmic scale. On this scale, a straight diagonal upward line indicates exponential growth rate. Here the projected number of cases doubling in two, three and five days is illustrated with the grey dashed lines.  This illustrates that the rate of spread in the Bailiwick is starting to decline.
