Let’s go back to 1976 for a brief review of…
Legionnaires’ Disease & Legionella
Legionella (101) – The Science Basics

The cause of Legionnaires’ disease was a common aquatic (water) bacteria!
It Was Soon Discovered . . .

• Mild, flu-like illness—without pneumonia• Appears w/in 24 hours to 3 days after
exposure• Lasts up to 5 days, generally less• Does not require hospitalization or
antibiotics• Susceptibility: ~95% (±) of those
exposed
Legionellosis: Pontiac Fever

Legionellosis: Legionnaires’ Disease

Disease Cause & Transmission Sources

Legionellosis is not transmitted from person to person – It is not a contagious disease *
• Inhalation (into the lungs) of water aerosols or soil containing LB, can cause disease
• Aspiration (into the lungs) of water/fluids resultant of gagging/swallowing/etc. problems, can cause disease
*Probable Person-to-Person LD transmission reported in N Engl J Med. 2016;374:497–8. (Son/48-Mother/74; Portugal; Oct/2014)

• Gram negative, rod-shaped, aerobic bacterium
• 60+ species and 70+ serogroups have been described for the genus Commonly found, natural inhabitant of
fresh waters, muds and some soils Survives and multiplies as intracellular
parasites in certain Protozoa (amoebae)

What filter size would you use for a Legionella control strategy?
Legionella Bacteria are …
Very, very, very, very …
small bacteria0.3–0.9 µm (by)
2–20 µm
![Page 24: Disclosure of Commercial Interests - MemberClicks](https://reader036.vdocuments.net/reader036/viewer/2022071816/62d49a129b339615cd22dd87/html5/thumbnails/24.jpg)
• Legionella is not ubiquitous (everywhere) in water systems or devices • It is a common bacteria and natural inhabitant of fresh waters, muds
and soils – generally, in very low levels and not causing disease• Scientific evidence: a wide variance, but found in ~30-70% of premise
plumbing (man-built) systems – if/when favorable conditions present • That’s what ASHRAE Standard 188 is about – managing building water
systems that can/could harbor Legionella!
Let’s Not Misunderstand ‘Ubiquitous’

1.Enter the host, penetrating deep into the alveolar regions of the lungs …
2.Macrophages come to ingest and destroy the invading bacteria;
However, Legionella survive & multiply within the macrophage, as they do in nature – living within host Protozoa (Amoebae) …

3.The Legionella ultimately lyse (burst open) the macrophage cell, killing it, while releasing many new Legionella and worsen the infection

• The potable (domestic) water distribution systems of large buildings, including hospitals and hotels, are considered the primary source of Legionella and disease as supported by peer reviewed research data and expert sources, such as the CDC
• Cooling Towers - long thought to be the major source for Legionella and disease - are considered an overemphasized exposure source according to current data.

Who Would Think – A Grocery Store?• An ultrasonic mist-maker device
was operating over one section of the produce display …
• No one at the grocery store was familiar with the operation or maintenance of the device …

► State Health Officials hold the keys to Legionella prevention …
• Regulations are ultimately needed for facilities to implement WMPs, state officials hold the keys to preventing Legionnaires’ disease – as states are the entities most likely to regulate.
• The CDC won’t establish regulations. It has influence but does not issue regulations.• The EPA focuses on water distribution up to the street tap, not on systems within
buildings.• Water treatment professionals, engineers, and consultants can continue talking about
better methods and procedures – but the information won’t prevent disease unless it changes the way building water systems are designed, operated, and maintained – which, will invariably depend on regulations to do so.
Ultimately, then, it’s up to health departments or other state agencies.

► Regulations based on a Standard can be established quickly …
• CMS simply issued a memorandum that hospitals and nursing homes must implement a WMP that reduces the risk of Legionnaires’ disease
• The entire memorandum was less than 3.5 pages, primarily background information. The directive itself consisted of only three sentences!
• With just the stroke of a pen, CMS did more to increase Legionellaprevention in hospitals and nursing homes than had been accomplished with decades of guidelines, warnings, standards, articles, speeches, conferences, seminars, webinars and e-courses!
CMS could not have established the requirement so simply or quickly without a standard (ASHRAE 188) to reference as a guide for WMPs.

►ASHRAE Standard 188 is the best standard on which to base Legionella regulations – why?
• It is ready – here and now – waiting for a “better” standard will cost health and life.
• It is in continuous maintenance – there is a formal process for accepting and considering comments and making changes.
• 188 outlines the essential elements and framework for a WMP – states can monitor documentation for specific procedures and performance criteria they deem imperative.
• ASHRAE has proven trustworthy …

SummaryLegionella is a common bacteria in man-built water systemsDisease causation is not simple – involves many factors:
• favorable conditions for LB growth, means of transmission (aerosols) and exposure route to susceptible persons
Cooling water and potable water systems all important There IS a ‘standard of care’ – not ‘best practice’ – that has
gained recognition and is required by certain AHJs for Legionellosis Risk Management in Building Water Systems –ASHRAE Standard 188.
