An outbreak of Legionnaires’ disease that began in Melbourne last week has claimed the lives of 2 people – a man in his 60s and a woman in her 90s. It’s a rare but severe form of bacterial pneumonia and there are now 77 confirmed cases, and 75 of those have required hospitalisation. That makes it the largest outbreak since 125 people were infected at Melbourne Aquarium back in 2000… Yesterday Victoria’s Chief Health Officer Clare Looker said the outbreak may be slowing, and “hopefully we’re seeing the tail of things.” It’s thought the outbreak started in a water cooling tower in an industrial building somewhere around the western suburbs of Laverton North or Derrimut. Testing has been carried out on 54 of 100 local towers, but Looker warns the source may never be found.
