9 May
Summary
- Hamilton Public Health is investigating 13 legionellosis cases since May 4.

- High-risk groups include adults over 50 and those with weakened immune systems.
Hamilton Public Health has launched an investigation into a cluster of 13 confirmed legionellosis cases reported since May 4. The affected areas are primarily in the city's east end and Stoney Creek. Legionellosis is a lung infection caused by legionella bacteria, which can lead to Legionnaires' disease or Pontiac fever.
Officials are working diligently to identify any common sources of exposure, though none have been confirmed as of the latest update. The bacteria commonly thrives in warm water environments and can be found in systems like cooling towers, hot tubs, and humidifiers. Public health reminds residents that the disease is contracted through inhaling contaminated water droplets, not through person-to-person contact.
Symptoms of legionellosis include fever, chills, cough, and shortness of breath. Individuals experiencing these symptoms are advised to consult a healthcare provider. Hamilton Public Health has alerted hospital partners and is examining potential exposure sites, including nearby cooling towers. They also advise regular maintenance of household water systems. Certain groups, such as adults over 50, smokers, and individuals with compromised immune systems or underlying health conditions, are at a higher risk for severe illness.
