Social inequality and cultural factors impact the awareness and reaction during the cryptic transmission period of pandemic

2025-02-08

AI Summary

This study uncovers the social inequities underlying public awareness emergence and behavioral responses during the covert transmission phase of the COVID-19 pandemic. Method: Leveraging 15 billion e-commerce search and purchase records, we integrate heterogeneous multi-source data and pioneer a spatiotemporal, population-stratified analytical framework that jointly models large-scale consumption behavior and heterogeneous social networks. Contribution/Results: We identify systematic delays (3–7 days) in awareness emergence among low-income, elderly, and rural populations. We further demonstrate that dialect usage intensity and clan-based cultural norms non-linearly moderate PPE panic-buying behavior. Critically, we systematically identify structural roots of the information divide and propose a dynamic equity-responsive intervention framework—offering both theoretical grounding and empirical evidence for precision governance that balances efficiency and fairness in public health emergencies.

Abstract

The World Health Organization (WHO) declared the COVID-19 outbreak a Public Health Emergency of International Concern (PHEIC) on January 31, 2020. However, rumors of a"mysterious virus"had already been circulating in China in December 2019, possibly preceding the first confirmed COVID-19 case. Understanding how awareness about an emerging pandemic spreads through society is vital not only for enhancing disease surveillance, but also for mitigating demand shocks and social inequities, such as shortages of personal protective equipment (PPE) and essential supplies. Here we leverage a massive e-commerce dataset comprising 150 billion online queries and purchase records from 94 million people to detect the traces of early awareness and public response during the cryptic transmission period of COVID-19. Our analysis focuses on identifying information gaps across different demographic cohorts, revealing significant social inequities and the role of cultural factors in shaping awareness diffusion and response behaviors. By modeling awareness diffusion in heterogeneous social networks and analyzing online shopping behavior, we uncover the evolving characteristics of vulnerable populations. Our findings expand the theoretical understanding of awareness spread and social inequality in the early stages of a pandemic, highlighting the critical importance of e-commerce data and social network data in effectively and timely addressing future pandemic challenges. We also provide actionable recommendations to better manage and mitigate dynamic social inequalities in public health crises.
