Legionella are bacteria that cause various clinical illnesses in humans, from flu-like symptoms to severe pneumonia. They are globally spread environmental germs, which in small numbers are natural components of surface and ground water. Legionella reproduce best at temperatures between 25 °C and 45 °C. Above 60 °C they are usually killed off and below 20 °C they hardly reproduce at all. Especially in artificial water systems such as water pipes in buildings the pathogens find good growth conditions at appropriate temperatures. Legionella can multiply particularly well in deposits and coatings of the pipe system.
The regular (at least twice a week) standardised flushing of the water tapping points (taps, showers, e.g.) prevents water stagnation and the potential health hazard of legionella. However, there is no danger during normal use of your rented apartment.
Legionella can cause two different diseases:
The pathogens are transmitted by atomized, nebulized water. The pathogen-containing droplets can spread in the air and be inhaled. This means that there is only a risk of infection when water containing the pathogen reaches the lungs via the windpipe. Possible sources of infection include showers, whirlpools, humidifiers or taps. There are also many other possible sources of infection. In rare cases, infection is possible when drinking water that accidentally enters the lungs via the windpipe when swallowed. Important: Legionella are not transmitted from person to person.
Sediments of chalk and corrosion particles favour the growth of microorganisms. For this reason, shower heads and hoses as well as aerators should be decalcified regularly, e.g. with diluted vinegar essence.
During longer periods of absence (holidays, business trips, e.g.) the water pipes in the apartment must be flushed regularly (twice a week) so that no water standstill occurs in the pipes and thus legionella reproduction is prevented. If the tenant is absent, this must be ensured by the 3rd person.
FIZZies are informed and aware that he/she is responsible for regular hygienic flushing of the water points (taps, showers, e.g.) in the apartment. In case of absence, they can register themselves to the house management to include them in our hygienic plan, which is regularly carried out by one of our trustworthy staff on site.
Live long and prosper ✌️
