Effects of information-dependent vaccination behavior on coronavirus outbreak: insights from a SIRI model
Abstract A mathematical model is proposed to assess the effects of a vaccine on thetime evolution of a coronavirus outbreak. The model has the basic structure of SIRIcompartments (susceptible-infectious-recovered-infectious) and is implemented by tak-ing into account of the behavioral changes of individuals in response to the availableinformation on the status of the disease in the community. We found that the cumu-lative incidence may be significantly reduced when the information coverage is highenough and/or the information delay is short, especially when the reinfection rate ishigh enough to sustain the presence of the disease in the community. This analysis is in-spired by the ongoing outbreak of a respiratory illness caused by the novel coronavirusCOVID–19.
