OSU begins its Covid trace testing throughout neighborhoods in Redmond tomorrow.  Residents will be invited to take part in the research, and will self-administer the test.  Results are expected within 10 days.  Researchers at the school say their goal is to test 600 people in the city to calculate the overall presence of the virus in a specific community.  The school has already conducted trace testing in five other cities throughout the state, including Bend.  The testing in Redmond will continue through Sunday.
