During disasters and emergencies (earthquakes, pandemics, economic crises etc.), we also face a second challenge, pollution of information. The transmitted information may be false, potentially harmful and speculative. Today, the main source of information seems to be the social media, which behaves as a vector via sharing news. In this presentation, the concept of the transmission dynamics of vector-borne diseases is adapted to the transmission dynamics of vector-borne disinformation [1]. The dynamical behaviour of the model is analysed, the disinformation-free and disinformation endemic equilibria of the model are found and both their local and global stabilities are presented [2]. Finally, numerical simulations are carried out to support the analytical results of the dynamical transmission of disinformation. This is a joint work with Meltem Gölgeli from TOBB Economics and Technology University.
