Recruitment notifications were sent by mail for the “Key to Oregon” research study led by Oregon Health & Science University to develop information about COVID-19 to help reopen the state, and keep it open. Study researchers expect to contact 150,000 randomly selected households who fully represent the state, including diversity in geography, socioeconomic status and communities of color. All members of a selected household over the age of 18 are eligible to join. The study hopes to enroll up to 100,000 participants. Participation in the study is voluntary. Households selected to participate will first receive a post card that will alert them of forthcoming enrollment information. A mailed letter, with specific directions to guide online enrollment, will follow shortly after.
