Analyses conducted on the public drinking water network have detected a low concentration of Legionella bacteria at one point. To date, no link has been established between the reported cases of legionellosis and this minor contamination in the distribution network.
As a precautionary measure, the SIAEPAVID and SAUR have intensified network surveillance and control actions. These include increased chlorination, enhanced water quality checks, targeted flushing operations, and expanded sampling to peripheral areas. A disinfection protocol is also ready for deployment if further analyses necessitate it.
Legionellosis is a lung infection caused by bacteria called Legionella, naturally found in aquatic environments. These bacteria can thrive in water systems under favorable conditions, particularly at temperatures between 25°C and 50°C. Contamination occurs through inhaling tiny droplets of contaminated water, such as during a shower, and it is not transmitted from person to person.
Symptoms of legionellosis can resemble those of the flu, including high fever, cough, breathing difficulties, chills, and other signs like nausea or confusion. Prompt medical consultation is recommended if symptoms appear.
The ARS (Regional Health Agency) states that the water supplied by the public network remains safe for consumption without any restrictions. The ARS also emphasizes the importance of maintaining private installations to prevent Legionella development.
It is advised to keep domestic hot water production temperatures between 55°C and 60°C, regularly flush water systems, especially after periods of absence, and maintain hot water tanks and showerheads. No new cases have been reported to date.
