How can I join the survey?
Households are selected at random from 15 counties throughout Washington state and are sent an invitation to participate in the mail.
Participants must be 0-85 years old. All children, teenagers, and adults of selected households are invited to provide a nasal swab for a COVID-19 test during the first collection. Children and adults ≥10 years old are invited to provide blood for the antibody test.
By collecting random samples from the general population, the survey will provide results that represent all of Washington state.
