There is an outbreak of C. difficile at a unit in the Juravinski Hospital.

Hamilton Health Sciences declared an outbreak at E3, a non-surgical medical unit, on Monday afternoon. There are four hospital-acquired cases in the unit.

E3 remains open, said spokesperson Heather Pullen. There are heightened infection prevention and control measures in place. Otherwise "the hospital is open and it's business as usual," she said.

This is the third C. difficile outbreak at a Hamilton hospital this summer. There were also outbreaks at Hamilton General Hospital's surgical trauma unit 6 South, and the Charlton campus of St. Joseph's Healthcare.

The St. Joseph's outbreak ended on Aug. 23, and the Hamilton General one on Aug. 24.

Hamilton Health Sciences has produced two videos on the subject. One gives general information about C. difficile, while the other demonstrates proper hand washing.
