The COVID-19 pandemic has exacerbated inequalities related to the digital divide. With the wide adoption of remote working and learning, telehealth, and virtual events and social activities, the technology have-nots and know-nots experienced substantial marginalization and elevated risks of COVID-19 exposure in daily lives. This study discusses the pathways through which digital exclusion could aggravate the impacts of the pandemic and explored the linkage between digital access and COVID-19 outcomes in U.S. counties. It finds that counties with higher percentages of digitally excluded populations have seen higher COVID-19 case and death rates throughout the pandemic and lower vaccination rates by January 2022.
