Urban and Rural Disparities in COVID-19 Outcomes in the United States: A Systematic Review.

Abstract

This systematic review investigates disparities in COVID-19 outcomes (infections, hospitalizations, and deaths) between urban and rural populations in the United States. Of the 3,091 articles screened, 55 were selected. Most studies (n = 43) conducted national analyses, using 2020 data, with some extending into 2021. Findings show urban areas had higher COVID-19 cases and hospitalizations in 2020, while rural areas saw increased cases in 2021 and mixed hospitalization results. Urban areas also had higher mortality rates in 2020, with rural rates rising in 2021 and 2022. Most studies did not explore reasons for urban/rural differences. The few that did found that vulnerable groups, including racially and ethnically minoritized populations, older adults, and those with comorbidities and lower socioeconomic status and vaccination rates, experienced exacerbated disparities in rural regions. COVID-19 outcomes varied over time and by area due to population density, healthcare infrastructure, and socioeconomic factors. Tailored interventions are essential for health equity and effective policies.
