In table 1 we presented the guidelines for the results interpretation of the
trials on Legionella in swimming pools (Pond, 2005).

Legionella in swimming pools (Pond, 2005)
Legionella (CFU/L) Interpretation/action required

≥ 100 to £ 1000 - resampling and follow/keep it under control
- review, risk characterization, and measures – refilling and sampling the next day

- stop the use of the pool and implement the measures

Measures in the event of an outbreak of legionellosis
Epidemiological indication is defined if we identify two or more cases in the
same community within six months when Legionella is confirmed. For the con-
trol of Legionella contamination in the pools is responsible The European Le-
gionnaires’ disease Surveillance Network (ELDSNet), which is coordinated by
the European Centre for preventive actions (European Centre for Disease Pre-
vention and Control - ECDC). Network is open to all EU Member States and al-
so Switzerland and Norway. By profession, experts are epidemiologists and mi-
crobiologists (European Centre for Disease Prevetion and Control, 2019).
National Institute for public health in Slovenia must investigate and con-
firm an outbreak of Leginella spp.. We took samples for microbiological anal-
ysis and the sampler must be authorized. The samples have to be examined in
the laboratory, which is accredited to ISO/IEC 17025 standard (International
Organization for Standardization, 2005) (European Centre for Disease Preve-�
tion and Control, 2019). Than the analysis of water samples is performed. Af-�
ter the confirmation of an outbreak or epidemy, the disease must be report-
ed to the National institute of public health. The x-ray of the lungs is necessary
to confirm legionnaire’s pneumonia. An epidemiologist has to perform envi-
ronmental anamnesis (European Centre for Disease Prevetion and Control,
2019). It is necessary to prohibit the use of the infected pool (European Centre
for Disease Prevetion and Control, 2019). In order to identify potential sourc�-
es of Legionella in the pool (swimming pools, pools with swirling warm water,
showers, or all resources that contain water with temperatures above 20°C and
can release aerosol), it is necessary to inspect the facility and take samples. It
is necessary to define and determine the risk. Swimming pools do not apply as
trials on Legionella in swimming pools (Pond, 2005).
