For the week ending yesterday there were 406 reported positive tests in Lane County, 178 of which were UO students or employees. As shown below, Lane county cases that are not linked to UO are decreasing, while UO cases are increasing:
Note that UO has a more rigorous testing regime for those students in the dorms than does Lane County, although this should not affect the marked difference in the changes over time much. UO has roughly 25,000 students and employees, total Lane County population is about 385,000. Data and sources here.
And I’ll add a pitch for UO’s program to provide free testing for Lane County residents at Mac and Matt Courts, info here.
