Legionellosis cannot be got from water you drink that enters your stomach in the normal way – the bacterium has to get into the lungs through breathing it in. The illness is not spread from person to person.
Z legionelozo se ni mogoče okužiti s pitjem vode, ki pride v želodec po običajni poti, ampak samo z vdihavanjem bakterije, ki nato pride v pljuča. Bolezen se ne širi s človeka na človeka.
