121 students living in fraternity houses at the University of Washington have tested positive for COVID-19. A pop-up testing site set up last week near the Greek Row section of the campus had conducted nearly 1,300 tests as of this weekend, the Interfraternity Council said.

School officials said they are still collecting and verifying the status of cases — and warned there may be more. The university reported 213 cases across all three of its campuses as of July 5.
