The COVID-19 pandemic has worsened health disparities worldwide. Across all nations, the burden of COVID-19 has fallen most heavily on the socially disadvantaged. In the United States, the COVID-19 mortality rate for Black Americans is over twice that of their White American counterparts, and people in prisons have more than double the COVID-19 mortality rate of the general U.S. population. Other social dimensions such as income, gender, sexuality, and immigration status have also played a significant role in COVID-19 infection, hospitalization, and mortality. The Social Epidemiology of the COVID-19 Pandemic provides an interdisciplinary analysis of the pandemic's effect across populations and its disproportionate impact on vulnerable groups in society, including racial/ethnic minority, immigrant, and incarcerated populations. Written by leading international scholars, this essential volume describes how the COVID-19 pandemic intersects with nearly every social determinant of health, from race and ethnicity to income inequality, and how such interactions compound existing structural disadvantages. Using examples from upper-middle and high-income countries such as the United States, contributing experts delve into the differential impacts of COVID-19 by major social determinants of health and reveal the resultant effect of pandemic-related policy on health outcomes. Together, these authors underline the urgent need for further integration of social epidemiology into public health decision-making to ensure that every population receives the care it requires. Drawing from research across epidemiology, sociology, psychology, and public policy, The Social Epidemiology of the COVID-19 Pandemic illuminates the stark disparities exacerbated by the COVID-19 pandemic and the valuable insights from social epidemiology that can inform a more equitable pandemic response.
