The purpose of this paper is to demonstrate the flexibility of mathematical modelling and to prove that mathematical models can respond to a variety of biological challenges, including infectious diseases, represented here as “zombie” infections. Five different models are presented containing different variables. The first three models conclude with the fact that coexistence between humans and zombies is impossible, as this will eventually lead to the eradication of human beings. In the fourth model the existence of a cure for zombiism is taken into consideration, which enables humans to survive in low numbers. Only in the fifth model humans survive an outbreak relatively undamaged, by eradicating the zombies. Although in the different formulas different parameters were used, it becomes clear that in case of an outbreak, it has to be dealt with quickly. Despite being unrealistic, the findings of the zombie outbreak scenario can in real life be applied to examine diseases with dormant infection. As can be seen by the outcomes, mathematical modelling is very flexible.
