I contracted Legionnaires’ disease in a hospital. They sent me home with a low-grade fever and a cough. 1 week later my daughter found me on the floor of my bedroom, unconscious and covered in feces. I was taken to the hospital by ambulance and admitted into ICU, where 3 days later they diagnosed me with legionnaires’ pneumonia. What I don’t understand is why the hospital was not held responsible for my illness (they did a test on their HVAC system and found Legionnaires’ in the water).
It is possible that the hospital water distribution system was the source of the Legionella. You should contact your public health department for information; they might have cultured the hospital water supply.
