Properties of virus spread that the calculation requires, such as incubation time or human contact behavior, are never known exactly. We refer to these properties as input factors. With uncertainty in the input factors comes uncertainty in the output of the calculations, i.e., it can never be predicted exactly how many new infections there will be. However, with the help of uncertainty quantification, which is mapped in the platform, it is possible to estimate with which probability the result lies in a certain range.
