New York, Aug 4 : Researchers have developed a mathematical model that predicts how infectious disease outbreaks incorporate fear both of disease and of vaccines.
The model, named as Triple Contagion of disease and fears, helps better understand how pandemics can occur in multiple waves of infections, like those we are seeing with Covid-19.
Human behaviours like social distancing (which suppresses spread) and vaccine refusal (which promotes it) have shaped the dynamics of epidemics for centuries. Fear of a contagious disease can shift how susceptible individuals behave; they may take action to protect themselves, but abandon those actions prematurely as fear decays, said lead author Joshua Epstein, Professor of epidemiology at NYU School of Global Public Health.
