What is it about?
The study demonstrates that individual decisions to undertake testing and isolation are influenced by a cost-benefit analysis, where perceived risk of infection, influenced by observed prevalence, plays a crucial role. This behavior, in turn, affects disease transmission and mortality dynamics. The developed analytical framework shows that failing to account for testing and isolation behavior results in an underestimation of infection propagation and fatality rates when reported disease prevalence is low, which may skew containment strategies. The findings highlight the importance of enhancing testing capacity and public health messaging as a critical countermeasure for future contagions like COVID-19.

Why is it important?
The research provides a critical understanding of the interplay between individual behavior and disease transmission. By incorporating behavioral responses into standard epidemiological models, this study offers valuable insights for managing current and future pandemics. The findings emphasize the necessity of robust testing strategies and public awareness to mitigate the spread of infectious diseases.
Perspectives
I am excited that this article is published in PLoS ONE. What began as an initial exploration of mathematical epidemiological models in March 2020 to understand the complexities of disease mortality projections, has evolved into what could be a framework for future pandemic preparedness. For many, COVID-19 is a thing of the past, and the world has moved on. However, for some like myself, the critical question is about what we have learnt from the experience and how the lessons from the pandemic can be used to control future pandemics. This piece of work has been quite satisfying as it attempted to uncover the nuances of silent spread of SARS-CoV-2 associated with symptomless infections, which was a major public health risk factor in the initial phase on the pandemic. This work was also an attempt on my part to build a much needed bridge between economists and epidemiologists - a gap that was starkly visible in policymaking around COVID-19. The paper demonstrates the usefulness of incorporating human perceptions of disease risk and related behaviors into standard epidemiological models and public health policies.
