Winnipeg – Victoria General Hospital in Winnipeg has had to place five patients in isolation. The fifth floor of the hospital has been hit by methicillin-resistant Staphylococcus aureus, or MRSA, a so-called superbug that’s immune to almost all antibiotics. “We had a patient who had MRSA who was discharged,” says Ray Racette, president and CEO of the Victoria Hospital. “And then we routinely test patients on that unit two weeks later to make sure that the bug has been eliminated. It was during that surveillance testing that we discovered five patients had MRSA.” Those five patients are being treated with vancomycin, the only antibiotic that can kill MRSA. Racette says treatment could take three or four weeks. In the meantime, all visitors to the Victoria Hospital’s fifth floor will have to don gowns and masks.
