Legionellosis incidents are much less frequent, but also more significant, and may lead to serious health complications, being fatal in a significant number of cases.

Some points we must take into account are:

• Identification of high-risk facilities.
• Sampling in accordance with UNE Standard 100030:2017
• Staff training.
• Documentation tailored to the establishment.
• Maintenance of high- and low-risk facilities.
• Cleaning and disinfection methods.
• Record-keeping systems.
