Fig. A.2.

Long term simulation of the population model, without implementation of seasonal variation. Although this population model is based on the population model published by SSI in May 2020 SSI (2020a), this figure cannot in any way be considered as a long term prediction from May 2020, as it was well-known at that time, that a seasonal effect was present, which would cause a decrease in infections during the summer, and the model was at that time not suited for, nor capable of long term simulations. Thus the inclusion of this figure is for the sole purpose of showing the drastic effects of introduction of a seasonal variation, and how it contributed to reducing the amount of infections in the Spring of 2020.
