KORMOD – a simple model of the coronavirus epidemics in Norway in Sweden
The Swedish and Norwegian coronavirus epidemics are studied by means of a ludicrously simple spreadsheet model, named KORMOD. The prevalence of infectious people is calculated as the sum of all individuals infected 3 to 9 days earlier, or by applying the gamma-shaped serial time interval distribution used by the Imperial College in their March 30 report. As it turns out, these two assumptions produce very similar results. As of April 24, 2020, the basic reproduction number is seen to be well below 1 in Norway, and well above 1 in Sweden. This seems to be true even if the incidence (and hence also the prevalence) of coronavirus infections should be grossly underreported.
