Basel, Switzerland โ Health authorities in Basel have reported an outbreak of Legionnaires' disease, a severe lung infection caused by the Legionella bacterium, which has led to 26 confirmed cases and one fatality. The outbreak has prompted an urgent investigation into the potential sources of contamination within the city.
We are currently observing a surge in cases of Legionnaires' disease (Legionellosis). These are pneumonias caused by the bacterium Legionella pneumophila.
Suspicion has fallen on the cooling towers of an office building, with preliminary investigations indicating they may be the origin of the bacteria's spread. The Department of Health for the Canton of Basel-Stadt stated that they are observing a significant rise in Legionnaires' disease cases, characterized by pneumonia caused by the Legionella pneumophila bacterium. Of the 26 individuals affected, nine remain hospitalized, and one is in intensive care.
Further analysis of cooling water systems in the vicinity of the outbreak has revealed alarming levels of bacteria. Out of ten installations examined, eight exceeded the legally permissible threshold for Legionella. Notably, two cooling towers located on the roof of an office building were found to contain high concentrations of Legionella pneumophila and have since been shut down. Other analyzed installations contained only non-pathogenic strains of the bacteria.
One person has unfortunately died, and another is still in intensive care.
Authorities are advising the public to seek medical attention if they experience symptoms of pneumonia, such as shortness of breath, fever, or a severe cough. The city, situated near the borders of France and Germany, is working to contain the spread and identify any further sources of contamination.
The occurrence of this cluster suggests the existence of one or more common sources of contamination.
