Dynamics of an Infectious Disease Where Media Coverage Influences Transmission

Abstract

<jats:p>There is significant current interest in the application of media/psychosocial effects to problems in epidemiology. News reporting has the potential to reach and to modify the knowledge, attitudes, and behavior of a large proportion of the community. A susceptible-infected-hospitalized-recovered model with vital dynamics, where media coverage of disease incidence and disease prevalence can influence people to reduce their contact rates is formulated. The media function is incorporated into the model using an exponentially decreasing function. Qualitative analysis of the model reveals that the disease-free equilibrium is locally asymptotically stable when a certain threshold is less than unity. Numerical results show the potential short-term beneficial effect of media coverage.</jats:p>

A stochastic SIS epidemic model incorporating media coverage in a two patch setting

“…As a result, a wide range of tools, including media coverage, have been deployed in an effort to control the epidemic diseases spreading [2][3][4][5][6][7]. And various models have been used to study different aspects of diseases spreading [8][9][10][11][12][13][14][15][16][17][18][19][20].…”

Analysis of variable structure of the disease spread with media impact

“…S.Samanta [11] showed the influence of media coverage with the conscious and the unconscious susceptible. Jean M [12]use exp(−M (t))λS to show the effect of media, where M (t) is symbolic function and λ is the force of infection.The mathematical model is carried out with some assumptions and ideal conditions. The models above assume that when a disease appeared, the media coverage began to affect the spreading of the disease.…”

Impacts of TV and radio advertisements on the dynamics of an infectious disease: A modeling study

“…Over the past few decades, several mathematical studies have been done to assess the effects of media campaigns for the control of infectious diseases . In previous studies, it is assumed that the number of awareness programs is implemented proportional to the number of infected individuals by considering media as a dynamic variable or transmission rate as decreasing function of number of infected individuals due to media alerts.…”
