The spread of awareness and its impact on epidemic outbreaks

The spread of awareness and its impact on epidemic outbreaks

The article explores the impact of awareness on the spread of infectious diseases. It models the spread of awareness through social networks and links it to an epidemiological model where more informed individuals reduce their susceptibility. In a well-mixed population, awareness can lower the size of an outbreak but does not affect the epidemic threshold. However, if awareness spreads locally, it can prevent disease spread if the infection rate is below a threshold. The effectiveness of locally spreading awareness is enhanced when the social network structure and communication networks overlap, especially if the networks have high clustering. The study highlights the importance of considering individual behavioral responses and social network structure in predicting disease outbreaks.The article explores the impact of awareness on the spread of infectious diseases.
