Abstract:
|
COVID-19 remains a serious problem in the United States with more than 30 million cases and 553,000 deaths reported through April 2021. The epidemic has had a disproportionate effect on communities of color and persons with lower levels of socioeconomic status, and has spread from larger metro areas to smaller cities and rural communities. We will examine potential disparities in both the disproportionate prevalence of COVID-19 as well as COVID-19 vaccination rates among racial/ethnic minority groups and groups with lower levels of socioeconomic status (SES). We will analyze data from our repeated cross-sectional study of sera from national commercial clinical laboratories using data aggregated over 15 biweekly rounds of antibody testing. We will merge data on demographic and socio-economic status (SES) characteristics at the county level from the American Community Survey (ACS) separately with a) daily and weekly vaccination data reported by states to the CDC, and b) our aggregate seroprevalence data. We will develop mixed multilevel models for seroprevalence that account for the county-level variations in the demographics and SES.
