## Abstract

PROJECT SUMMARY/ABSTRACT
To have an optimal response to the COVID-19 epidemic, it is important to understand the proportion of adults
in the United States may have the virus that causes COVID-19, and how many have had it in the past and may
have immunity. Currently available data are limited because the impact of asymptomatic and mildly
symptomatic cases is unclear and many people are unable to access a test due to rationing, or may be
otherwise unwilling to go for testing or care. This study will address this problem by conducting a national
probability sample, where each address may be selected by chance, to develop estimates of the proportion of
adults in the United States that are infected with the virus that causes COVID-19, and the proportion that has
had the disease in the past and may now have immunity. We will use home-based testing techniques to
facilitate participation in this national study. We will also use surveys to better understand participants in our
sample. With these estimates, we will conduct disease modeling to understand different scenarios of the
epidemic. We will also develop a website to provide information and data to the public.
