The state will pick 1,200 households randomly from across the state. These Ohioans will receive a postcard, followed by a letter notifying them of their selection, and when to expect a team of ODH workers to visit their home. During the visit, one adult will be randomly picked for testing.
Participation is voluntary. Anyone who is picked can opt out of testing by phone or email beforehand, or turn away ODH workers in person.
