HALIFAX -- The city of Fredericton remains on edge as health officials eye a cluster of cases traced back to a University of New Brunswick residence. The university has extended its campus lockdown until Sunday, after advice from public health. Two more cases have been connected to UNB’s Magee House, bringing the total to eight. Residents of another UNB building next to Magee House have also been tested, with results expected in the coming days. “As you can appreciate this situation is continuously changing. As more contact tracing and testing is completed, plans and actions are revised and this information is provided to students,” said Heather Campbell, acting director of communications for UNB. “Some of the services and supports put in place so far include enhanced cleaning and sanitation, grocery delivery, counselling services, activities for the children in Magee House, offering onsite medical support, and a plan for laundry.”
