The impact of deniers on epidemics

In the wake of COVID-19, we have witnessed a spread of misinformation about the virus, which has created groups of deniers of the situation. What can be their effect on the spreading of the virus?

In their new work, our Prof. Maurizio Porfiri along with Lorenzo Zino (University of Groningen, now Polytechnic University of Turin) and Prof. Alessandro Rizzo (Polytechnic University of Turin) studied the epidemic spreading of a disease in a population divided into two groups: cautious and deniers. This division was formed on the basis of people’s attitudes towards adopting or not adopting public health measures in different degrees, depending on the polarization of the public debate. The researchers showed that even small groups of deniers can have a significant effect on the spreading of the virus, when the public debate is highly polarized.
