One of the main ways that Legionnaires disease can spread from hot water heaters is through aerosolization This occurs when the bacteria are present in the water and are released as droplets into the air These droplets can then be inhaled by people in the vicinity, leading to infection Showers, faucets, and other sources of hot water can create aerosols that spread the bacteria, putting individuals at risk of contracting Legionnaires disease.
Another way that Legionella can spread from hot water heaters is through biofilm Biofilm is a slimy layer that can form on the surfaces of water systems, providing a protective environment for bacteria to grow Legionella bacteria can hide within biofilm in hot water heaters, making it difficult to detect and eradicate Over time, the bacteria can multiply and spread throughout the water system, increasing the risk of infection for those who come in contact with the contaminated water.
