Holiday Water Line Rinsing Required to Prevent Post-Vacation Legionnaires' Disease

Legionella, the bacteria responsible for Legionnaires' disease and Pontiac fever, is not contagious and does not spread from person to person [1]. While it can occur in cold water, it does not multiply significantly below 20 degrees Celsius [2].

Legionnaires' disease, a severe form of the infection, can cause confusion and pneumonia, which typically develops rapidly with chest and head pain, cough, chills, and high fever above 40 degrees [3]. Pontiac fever, a milder form, presents with symptoms similar to the flu, including fever, malaise, headache, muscle aches, and chest pain and cough [4].

Individuals with weak immune systems, certain chronic illnesses, and older people are at a higher risk of contracting Legionella [5]. It's essential to be aware that in about one in ten cases, Legionnaires' disease can be fatal [6]. Moreover, Legionella can lead to a urinary tract infection [7].

To reduce the risk of Legionella infection, it's advisable to thoroughly flush all water pipes with hot and cold water for several minutes after a long absence [8]. This practice helps disrupt biofilm buildup and remove water where Legionella bacteria can thrive. Specifically, flushing taps involves running water for several minutes until the temperature stabilizes at safe levels and ensuring that water is flowing from all outlets, especially those infrequently used [9].

Cleaning faucet aerators and shower heads regularly is also important, as they can trap biofilms, which protect Legionella bacteria [10]. Routine cleaning or replacement reduces this risk.

Maintaining water system hygiene by regular disinfection or chlorination where applicable, and conducting risk assessments to identify vulnerable or unused parts of the water system, supports Legionella control [1].

A consistently high water temperature throughout the year is the best protection against unwanted Legionella multiplication [11]. At water temperatures above 55 degrees Celsius, Legionella growth is effectively inhibited, and above 60 degrees Celsius, the germs die off [12].

Opening windows and doors can help avoid exposure to contaminated aerosols, a common transmission route for Legionella infections [2]. Drinking Legionella-containing water is typically harmless, as the bacteria are killed by stomach acid [13].

AOK Service Region Manager Jörg Kock advises flushing water pipes before first use after a long absence to prevent Legionella growth [14]. He emphasizes the importance of following these safety measures to protect yourself and your family from this potentially dangerous bacteria.
