New York lawmakers are now trying to better protect residents from the deadly legionnaires’ disease by increasing regulations and inspections of cooling towers after two outbreaks of the infection over the last two summers and a raft of new lawsuits.
Legionnaires’ disease is a serious pneumonia caused by a bacterium called legionella. It often comes from large air-conditioning systems, like those used in hotels, hospitals and high-rise buildings, because the cooling towers contain water to remove heat. If not well maintained, the liquid can foster the bacteria, which can then be swept into fans and circulated through the air.
