Brief summary
The co-primary objectives of this study are to: 1. Determine and compare the COVID-19 antibody positivity rate in health care workers and patients without a known COVID-19 infection 2. Determine if PCR negativity for COVID-19 early in quarantine predicts negativity at Day 14 in quarantining individuals
Detailed description
This is a prospective cohort study designed to identify the prevalence of IgG antibodies to SARS CoV-2 as well as to assess risk factors for IgG positivity. It will compare rates of positivity and risk factors among healthcare workers and non-healthcare workers and assess the ability of PCR negativity at day 3 or 4, 5, 7, or 10 to predict negativity on day 14 in individuals quarantining after a COVID exposure. In addition to having a standard of care clinical antibody test, both healthcare workers, quarantining individuals, and patients will be asked to fill out a survey to assess risk factors for COVID infection and provide a research blood sample. Quarantining individuals will also have standard of care PCR testing on days 3 or 4, 5, 7, 10, and 14 of the quarantine period. Collected blood samples will be used to assess for the presence of neutralizing antibodies and measure antibodies with a research test. An annual blood specimen and survey will be collected from each study participant for up to 2 years total after study entry.
