James will need proof, which he will then try (in vain) to refute.
Legionnaires was isolated in the cooling towers of the air-conditioning of the building in Quebec City..
As you can see the building is little over 10 years old, and the cooling towers have been sprayed twice to kill all the pneumococcus legionella. Virtually the same situation as occurred in Philadelphia for the very first outbreak. It has nothing to do with cleanliness or dirtiness, it has to do with the wrong micro-organisms floating in on the air and contacting standing water which is cycled in order to cool the building.
Roughly 185 cases with 13 deaths.
But thanks for your care and concern, James, as if I'd make fun of a disease outbreak in Maryland.
