Two patients at a hospital severely criticised for its high mortality rates and poor hygiene standards are feared to have contracted life-threatening legionnaire's disease.This disease is typically spread via air conditioning or water systems, (Mayo Clinic) among other things.
Now I a not going to extensively research legionnaires' disease, but if memory serves, there are standard maintenance chores that can reduce the occurrence of this disease. This may just prove to be an unhappy coincidence, but the hospital in question was already dinged for slack maintenance.
Why? Because maintenance costs money.
