Hamilton Public Health is investigating a group of confirmed cases of Legionellosis, with a focus in the city’s east end and Stoney Creek.

Since May 4, there have been 13 reported cases to public health of the infection, which is caused by a bacterium mainly found in warm water environments.

Health officials are working to identify possible sources of exposure. Their investigation is focused in East Hamilton and Stoney Creek.

“We have identified a cluster of legionellosis cases in the east end of the city and are focused on identifying potential sources of exposure,” said Dr. Brendan Lew, associate medical officer of health. “We are working closely with local partners and reminding residents and facility operators of the importance of properly maintaining water systems and mist-producing devices.”

A possible source of exposure being investigated is nearby cooling towers. Local hospital partners have been notified to be on alert for potential cases.
