Legionnaires’ disease can be very serious and can cause death in up to 5% to 30% of cases or 2400 to 5400 people will die each year as many as 16 deaths each day.

Atlanta, GA – According to Building Operating Management magazine, expert Victor Yu, MD, Professor of Medicine, University of Pittsburgh; Chief, Infectious Disease Section, VA Medical Center, Pittsburgh, PA, USA disclosed

that “Up to 70% of all buildings greater than three stories in the US may be contaminated with legionella.”

Legionella PreventionThe Centers for Disease Control and Prevention reported in 2011, Legionnaires’ disease is on the rise, increasing by 217 percent in the last decade – or 18,000 to 20,000 cases annually in the United States. However, many infections are not diagnosed or reported, so this number may be higher. More illness is usually found in the summer and early fall, but it can happen any time of year. Legionnaires’ disease can be very serious and can cause death in up to 5% to 30% of cases or 2400 to 5400 people will die each year as many as 16 deaths each day. In December, a Texas newborn, who was water birthed, developed Legionnaires’ disease and passed after being exposed to the bacteria.

Dr. Rajiv Sahay, director of laboratory services at Environmental Diagnostics Laboratory (EDLab) a CDC ELITE lab stated that our “as a result of our

CDC ELITE credentials our clients are assured of highest accuracy scientifically and legally defensible data available.”  Dr. Sahay further stated that “we look forward to continuing to work with many facilities staff in helping them build a strong proactive Legionella program in their facilities.”

The long awaited ANSI/ASHRAE Legionella standard 188-2015 entitled:Legionellosis: Risk Management for Building Water Systemshas finally been adopted 5 years after it was first released.

The standard is intended for use by owners and managers of human-occupied buildings and those involved in the design, construction, installation, commissioning, operation, maintenance and service of centralized building water systems and components.  Facility managers are charged with conducting an annual survey to determine what risk is present in their buildings.   Specific risk factors called out in the standard include:

  • Multiple housing units with one or more centralized water heaters
  • More than 10 stories (including levels below grade)
  • Healthcare facility where patient care exceeds 24 hours
  • Cooling tower or evaporative condenser
  • One or more whirlpools or spas within or adjacent to building
  • Devices that release aerosols (e.g., ornamental fountains, misters, air washers or humidifiers, cooling towers)
  • Incoming potable water containing less than 0.5 ppm residual halogen such as chlorine
  • Inpatient health care facility
  • Occupants primarily older than age 65
  • Occupants receiving chemotherapy for cancer or bone marrow transplantation

Francisco Aguirre, Director of Building Sciences at Pure Air Control Services stated “legionella bacteria is found naturally in the environment, usually inwater. The bacteria grow best in warm water, like the kind found in cooling towers, hot water tanks, misters, atomizers, plumbing systems, HVAC systems, potable water or decorative fountains and hot tubs.’
