HALIFAX -- Nine people who were in the Halifax Infirmary's non-COVID unit are now fighting the virus after infection seeped into their section of the hospital. "All those patients have been transferred to the COVID unit and are being cared for there," said Dr. Robert Strang, Nova Scotia's chief medical officer of health. The investigation is still ongoing, but Strang says every patient that comes into the hospital is tested for COVID-19. Still, Dr. Robert Strang indicated the virus was brought into the unit by a patient, not a staff member. "It’s quite likely that there was an individual, their first test was negative, but they were very early on an infection and they subsequently became positive and became infectious," Strang said.
