Frequently Asked Questions


  • What is Legionella?

    Legionella is a rod-shaped bacterium (of which there are approximately 40 different species) invisible to the naked eye. It is entirely natural and naturally present in aquatic environments such as lakes, rivers, and springs, but can easily colonize artificial systems such as water distribution networks, air conditioning systems, and domestic hot water storage facilities. In particular, the species Legionella pneumophila can cause Legionnaires' disease, a potentially serious respiratory infection contracted by inhaling contaminated water microdroplets (aerosols).

    Those most at risk are immunocompromised individuals, the elderly, frequent travelers, or hospital patients. The bacteria is not transmitted by ingestion, but by inhalation, for example, when using showers, air conditioners, decorative fountains, whirlpools, or cooling towers.


  • Is it dangerous to human health?

    Unfortunately, bacteria of the Legionella genus, particularly the pneumophila species, can cause serious infectious diseases, usually affecting the respiratory system (Legionellosis). This disease is statistically fatal in 5 to 15% of cases, with much higher fatality rates in individuals with specific conditions, such as patients already in poor clinical condition or those treated late. Those most at risk are generally the elderly, immunocompromised individuals, individuals with chronic lung disease, heavy smokers, frequent travelers, and so on.

  • How do you get Legionnaires' disease?

    First, it should be clarified that drinking water containing Legionella bacteria does not pose a risk of infection. The disease is contracted solely by inhaling tiny water droplets (aerosols) containing high concentrations of the pathogenic microorganism. Risks of inhaling the bacteria may arise near faucets, shower stalls, decorative fountains, carpet cleaners, hot tubs, humidifiers, cooling towers, air conditioners, etc. Statistically, in hotels, the areas most at risk are shower stalls and air conditioning outlets.

  • When is it necessary to sanitize?

    Legionella sanitization is particularly recommended:

  • during the seasonal reopening of hotels or accommodation facilities

  • after periods of inactivity of the water systems

  • following abnormal bacterial findings

  • as a preventive measure in healthcare facilities, nursing homes, gyms, schools and hotels.


    • Prevention is the only effective tool to avoid infections, sanctions, and operational blockades.
