Misinformation makes it harder to stop pandemics according to international researchers, who say public health messages can be undermined by competing misinformation and conspiracy theories, spread virally through communities that are already distrustful of expert opinion. The team used computer models with both trusting individuals who seek better quality information and will take precautionary measures, and distrusting individuals who reject better quality information and have overall riskier behaviour. They found that as the proportion of the distrusting population increases, the outbreak becomes harder and harder to stop until it cannot be suppressed.

Misinformation can prevent the suppression of epidemics

Journal of the Royal Society Interface

During a pandemic, the effectiveness of precautionary measures, such as social distancing, depends on how closely the public adheres to health guidelines. Dissemination of incorrect information within communities distrustful of expert opinion can cause reluctance and jeopardise epidemic control. In this article, we model the entwined dynamics of disease and behavioural reaction to its prevalence in a population of individuals who either trust or distrust responsible health agencies. We show that major outbreaks cannot be suppressed once the density of distrusting individuals exceeds a threshold. Our findings highlight the importance of effective interventions to build trust and inform the public.
