Natural habitat
Legionella
can be present in
any natural water source
Contact with aerosol
The risk is also related to
how people have contact
with contaminated aerosol
Diagnosis of the disease
Identified by symptoms,
laboratory testing and
surveillance of locations
affected by outbreaks of
legionella
Spreading out of the system
There aremany parts of the
systemor equipment that
produce aerosols / sprays as
cooling towers, showers, etc.
(temperature, humidity, amount
of aerosol)
(24) Process of proliferation
Host susceptibility
Gender, age, disease,
respiratory disease,
immunodeficiency, smokers
and diabetics
System contamination
Occurs by contaminated
water
Virulence
Bacterium very aggressive
to the host, and
Legionella
pneumophila sg1 requires
more care
Amplification system
There are several elements
that promote the growth
of
Legionella
(temperature,
contamination process, water
stagnation)
The possible places to have contact with
Legionella
include everything
from our own home, hospitals, restaurants, hotels, shopping malls,
clubs, offices, parks, streets, or anywhere, as the droplets of water can be
contaminated in all locations.
For
Legionella
species that are in water, the process of proliferating
respiratory diseases are as follows:
