Poiché le cause scatenanti sono molto diverse, e spesso rimangono oscure, la lotta si rivela molto difficile, sottolineano gli esperti.
Il batterio patogeno, denominato legionella, si moltiplica soprattutto in ambienti umidi creati dall'uomo (docce, nebulizzatori, sistemi di ventilazione), generalmente scatenando polmoniti di gravità variabile, mortale nel 5-15% delle manifestazioni.
