The outbreak of pneumonia of unknown origin, declared in Argentina and which claimed four deaths and eleven more affected, was caused by the Legionella bacterium. This was stated by the president of the Senate Health Commission, Pablo Yedlin. He has also assured that after sending the patient samples to the Malbrán Institute in Buenos Aires, they determined the positive for Legionella.
The Argentine Minister of Health, Carla Vizzotti, He has indicated, after clearing up doubts about what could have caused the outbreak of pneumonia, that this information is preliminary and that “it remains to be advanced in the final diagnosis is with serology». For his part, he has stressed that three of the four samples are respiratory and one is a biopsy. «A bacterium called Legionella is being isolated in the PCR and the last name of that bacterium is being typified. The suspicion is that it is pneumophila. From a health point of view, it is confirmed that it is an outbreak ofe pneumophila”detailed Vizzotti.
The outbreak of pneumonia – then of unknown origin – occurred on August 18 in a private clinic in Tucumán, which is located about 1,300 km north of Buenos Aires.
What is Legionella?
Legionella bacteria are naturally found in living environments. fresh water, such as lakes and streams. These bacteria can become a health concern when they multiply and spread in buildings’ artificial water systems, such as:
Shower heads and sink faucets
Cooling towers (structures that contain water and a fan as part of the centralized air cooling system in buildings or industrial processes)
Fountains and decorative accessories with water
Hot water tanks and water heaters
Large and complex piping systems
air conditioning systems from cars and houses that don’t use water to cool the air; therefore, they do not present a risk of multiplication of Legionella bacteria.
However, Legionella bacteria can multiply in the windshield washer fluid reservoir of a vehicle (for example, car, truck, van, school bus or taxi), particularly if the reservoir contains water rather than genuine windshield washer fluid.
how the bacteria Legionella they affect the water systems of buildings and people.
How it affects building water systems
Four key steps must be distinguished that can lead Legionella bacteria to multiply in water systems from buildings and spread to people.
After bacteria grow and multiply in a building’s water system, the water containing them can disperse in droplets small enough to be inhaled by people. People can get the disease of legionnaire or pontian feverc when they inhale droplets containing the bacteria.
Another less common way people can get sick is by breathing in drinking water that contains Legionella bacteria. This happens when water accidentally enters the lungs while drinking. Among the people most at risk of inhaling them are those who have difficulty swallowing.
Legionnaires’ disease and Pontiac fever are not usually spread from person to person. Nevertheless, this might be possible in rare circumstances
