What is Legionella?

Legionella is a genus of potentially pathogenic (Legionnaires’ disease-causing) bacteria that live in environmental water ecosystems, inside of free-living amoebae, and within the microscopically diverse water/surface biofilms. The genus Legionella contains at least 50 identified species and more than 70 different serogroups. The species L. pneumophila is responsible for 90% of the cases of Legionnaires’ disease, with L. pneumophila serogroup 1 the cause for virtually all community-acquired outbreaks of Legionnaires’ disease. 

What is Legionnaires’ disease? 

Legionnaires’ disease is an acute pneumonia caused by inhalation of an aerosol of environmental water containing an infectious dose of L. pneumophila, or less commonly, one of the other Legionella species. The disease can be rapidly fatal if not treated aggressively with the appropriate antibiotics, especially hospital-acquired infections in immunocompromised patients with underlying health conditions. 

The first documented outbreak of Legionnaires’ disease was at the 1976 convention of the American Legion, where 221 of the attendees contracted the disease which resulted in 34 deaths. The name of the disease and subsequent genus name originate from this outbreak.  Since then, there has been a steady rise in the recognition of outbreaks of Legionnaires’ disease, including the 2015 New York City outbreak in the South Bronx. During three weeks of the 2015 summer, 133 Legionnaires’ Disease cases, that resulted in 16 deaths, were documented and traced back to exposure of a single contaminated cooling tower on top of a hotel building.  Hospital-acquired infections are more common source of infection and are typically linked to exposure to contaminated hot water loops of the premise plumbing in healthcare facilities. Outbreaks from exposure to the hot water loops in hotels have also been documented.

Legionella Management in Building Water Systems

EST and Dr. Miller have provided our customers with the highest level of Legionella services and information since 1983 and we are prepared to assist you with ASHRAE 188-2021.  We can provide guidance in establishing your “Water Management Program”.

Does ASHRAE 188-2021 apply to you?

COVID-19 and Legionella

The impact COVID-19 has had on everyone extends to building water systems, both cooling towers, and potable water systems. Inactivity and limited use can contribute to the formation of biofilm allowing for Legionella proliferation. EST can assist in developing a reopening plan for your facility, including highly effective re-commissioning disinfection procedures and follow-up validation testing.
