Every year we hear about outbreaks of Legionnaires' disease that seriously affect the public, without knowing exactly what risks we are exposed. With this article we try to clarify the most common questions we are when it comes to Legionella and its consequences:

 

WHAT IS IT?

Legionella pneumophila is a gram negative bacterium environmental shaped bacillus is able to survive in a wide range of physicochemical conditions. Its natural habitats are ecological surface waters, which are part of the bacterial flora. Ideal conditions of temperature for the multiplication is between 20 and 45 ° C. From these natural reservoirs, the bacterium can colonize other areas through the distribution network of water.

 

HOW CAN AFFECT?

This species is the cause of legionellosis or Legionnaires' disease. Can appear as pneumonia or a febrile illness called Pontiac fever. The entry of Legionella occurs in the human body through the respiratory tract by inhalation of aerosols of water containing a sufficient number of bacteria, and can eventually lead to serious pulmonary complications. Therefore, the origins of the infections always find all those systems or devices that generate aerosols of water which can be inhaled by people, such as cooling towers, humidification systems, public fountains, irrigation systems Machine ...

 

Preventing proliferation?

Through effective prevention and control programs achieve significantly reduce the incidence of disease in the population. These programs, developed and implemented by accredited companies as established by law, involving among other actions:

· Carry out risk assessments following the technical guidelines of the Ministry of Health, Social Services e Equality.
· Having an efficient self-monitoring plan based on risk assessment, the scheme of the installation and the identification of critical points.
· Maintenance, cleaning and disinfection of the system elements.
· Prepare an analytical program that considers measures to take in case of occurrence of Legionella. Samples must be analyzed by accredited laboratories.
