Some students at a University of North Carolina dormitory have been placed in isolation after officials identified a cluster of COVID-19 cases.
The university said Saturday that a cluster of at least five cases has been identified at Avery Residence Hall.
The announcement comes a day after university officials said that unvaccinated students will now have to be tested twice weekly. The initial requirement was once a week.
Earlier this month, university officials announced a cluster of cases connected to an event at the school of pharmacy.
The university says 87 percent of students report that they have been vaccinated.
