OSU says it’s going to be trace sampling this Friday through Sunday in Redmond to determine the prevalence of the Covid 19 virus.  Researchers at the school plan to test up to 600 residents in 30 neighborhoods.  In addition, members of the city’s Public Works department will be testing sewage samples so they can be genetically evaluated.  The OSU Covid research began in April, and since then has conducted trace sampling and analysis in multiple cities throughout the state, including in Bend.
