简要总结
The overall goal of this study is to understand the immune response (IgG) to SARS-CoV-2 to fill critical knowledge gaps in the natural history of this virus and to inform the development of future infection mitigation efforts. The study team aims to assess the prevalence of circulating IgG antibodies to SARS-CoV-2 and the factors associated with sero-prevalence. These data will be used to estimate the total population that has been exposed to the virus (asymptomatic and symptomatic), the proportion of the population that may be protected by natural immunity, and the proportion that is susceptible. Data obtained from this research will be shared with the Florida Department of Health.
