A bacterium that affects the respiratory system

Legionella is a bacterium that can cause an infection of the respiratory system with a variable rate of severity. In the worst cases, it can cause pneumonia (Legionnaires' disease) with a mortality rate of 10-15%, or a benign flu-like illness.

The source of infection is the environment, as this bacterium spreads through city pipes and building water systems. The micro-organism is carried by small nebulised water particles (aerosols) and can be easily inhaled through the mucous membranes of the upper respiratory tract.

Favourable conditions for the proliferation of Legionella are stagnant conditions and the presence of encrustations, sediments and biofilms (i.e. a film of microorganisms immersed in an organic matrix). In short, this bacterium proliferates in unclean environments.

How to prevent the epidemic

How to prevent the epidemic

Given that Legionella can also be spread by air, through old and unclean filters in air conditioning or heating systems, in places such as gyms and swimming pools where there are communal bathrooms and showers in the changing rooms, it is essential to ensure a clean and healthy environment for the clients, athletes and staff of these facilities.

In addition to regular testing of water samples and periodic maintenance of the facilities through disinfection treatments, cleaning of the premises plays a fundamental role. This must be done by vacuuming both the dust, where the dried bacteria is pulverised, and the liquids where Legionella can easily nest.

Equipping rooms such as gyms or swimming pools with a central vacuum system from the Sistem Air Pro professional range guarantees thorough cleaning of all surfaces, not only removing dust but also liquid residues.

In this article on our blog we have already presented the ideal product to ensure clean rooms that are protected from the spread of Legionella.
