Abstract
The coronavirus disease 2019 (COVID-19) pandemic calls for accurate and timely risk assessment. Existing COVID-19 risk assessment research has been mainly conducted at the aggregate level (e.g., at the neighborhood level, census-tract level or county level), which presumes that people living in the same area are exposed to the same level of COVID-19 risk. However, people living in the same area may have different daily activities and travel to different places, thus leading to varying COVID-19 risk and much uncertainty in the assessment of people’s COVID-19 exposure. By col-lecting 7-day GPS trajectory data from 143 participants in Hong Kong, this study assesses indi-viduals’ exposure to COVID-19 risk using both the residence-based and the mobility-based ap-proaches. The differences in participants’ exposures to COVID-19 risk resulting from individual mobility are examined. Disadvantaged groups with higher COVID-19 exposures due to their res-idences or their mobility patterns are also identified. The findings in this study can help under-stand individual exposure to COVID-19 risk and inform policymakers of the social inequality in exposure risk to improve resource allocation and develop more targeted intervention strategies for different population groups and build an equitable pandemic-ready society.
