In this recursive calculation of epidemic, set the following parameters:[br]- Total Population ([color=#b20ea8]P[/color])[br]- Infected Population at start ([color=#b20ea8]start[/color])[br]- chance of contraction per contact between a susceptible and an infected person ([color=#d69210]rate[/color])[br][br]In the spreadsheet, column [color=#1551b5]B[/color] and [color=#0a971e]C[/color] show the [color=#1551b5]infected population[/color] and [color=#0a971e]new infections[/color] in each day respectively.
