What is Legionnaires’ Disease?

Legionnaires’ disease is a form of pneumonia caused when Legionella contaminated water is aerosolized and inhaled. People exposed to Legionella will not all develop Legionnaires’ disease. Some might develop a milder infection called Pontiac fever. In most instances, exposure risks to Legionella contaminated water can be prevented with the use of copper silver ionization secondary water treatment solutions.

The World Health Organization (WHO) acknowledges a lack of appropriate methods to diagnose the infection or sufficient surveillance systems to determine the exact rate of Legionella-related occurrence is unknown.

Legionnaires’ disease cases reported to CDC has risen since 2000. In 2018 alone, health departments reported nearly 10,000 occurrences of Legionnaires’ disease in the USA. Additionally, the CDC believes that these reported numbers are underestimated because Legionnaires’ disease is likely to be under-diagnosed and under-reported to the health authorities. A recent 2021 study estimated that the actual number of Legionnaires’ disease cases might be as high as 1.8–2.7 times higher than what was reported.|CDC|

Legionella is a waterborne bacteria that can be found globally. In addition to untreated evaporative cooling towers, both hot and cold facility potable water distribution networks are commonly identified to be the source of Legionella related Legionnaires’ disease outbreaks. It is estimated that larger facility potable water networks, with no secondary water treatment such as a commercial or medical grade copper silver ionization water treatment solution, account for over 80% of Legionnaires’ disease cases compared to less than 20% for cooling towers.
