Sample animations. The animations in wmf format provided with this manuscript show different single realizations or possible scenario of an unrestricted epidemic where one initial infected person is located in Stockholm. They are provided for interest only and should not be seen as contributing results, which require the combined analysis of many more realizations. The first file, Stockholm.wmf, shows a common scenario of spread throughout the country from Stockholm.

Uppsala.wmf clearly demonstrates the benefits of stochastic modeling in that the epicenter is spontaneously translocated to Uppsala, north of Stockholm, and the epidemic is hence delayed. This is quite a plausible event that would not be captured in deterministic models.

They are provided for interest only and should not be seen as contributing results, which require the combined analysis of many more realizations. Dies_out.wmf shows the common event of the epidemic not catching on but rather dying out within a few days. All these realizations have been aborted after 60 days.

The animations in wmf format provided with this manuscript show different single realizations or possible scenario of an unrestricted epidemic where one initial infected person is located in Stockholm. They are provided for interest only and should not be seen as contributing results, which require the combined analysis of many more realizations. Biggy.wmf is similar to the first but was not aborted until the epidemic has peaked and died out due to depletion of susceptible individuals.
