Data Collection and Reporting
This study examined the impact of variable infection risk by race and ethnicity on the dynamics of SARS-CoV-2 spread by fitting compartmental SEIR (Susceptible-Exposed-Infectious-Removed) transmission models structured by race and ethnicity to seroprevalence data from New York City and Long Island and analyzing how herd immunity thresholds, final sizes, and epidemic risk change across groups. The results highlight the importance of developing socially informed COVID-19 transmission models that incorporate patterns of epidemic spread across racial and ethnic groups.
