Disparities in Respiratory Syncytial Virus Risk Factors, Diagnosis, and Outcomes in Adults by Race, Ethnicity, and Other Social Determinants of Health in the United States.

INTRODUCTION

Respiratory syncytial virus (RSV) vaccination could improve health equity by protecting individuals who are disproportionally at increased risk of RSV infection and severe RSV-related outcomes. However, limited information is available about RSV-related disparities among United States (US) adults.

AREAS COVERED

We reviewed US-specific literature regarding disparities across adult populations in having risk factors for severe RSV disease (cardiopulmonary disease, diabetes, liver disease, kidney disease). We summarize available evidence regarding disparities in having or being diagnosed with RSV, as well as experiencing severe RSV-related health outcomes. Disparities are analyzed by race, ethnicity, socioeconomic status, and other social determinants of health.

EXPERT OPINION

RSV-related disparities are observed across all outcomes of interest, although RSV-specific data are limited in some cases. Racial and ethnic minority groups and socioeconomically disadvantaged populations are more likely to have risk factors for severe RSV disease, overall and at younger ages, yet individuals from these groups are more often underdiagnosed. Disparities in RSV-related hospitalizations, emergency department visits, and deaths are observed, especially among adults from racial and ethnic minority groups, of lower socioeconomic status, and in poorer or more crowded neighborhoods. Findings highlight the importance of RSV vaccination among these groups to improve health equity.
