Reminders about legionellosis :
Legionellosis (or Legionnaires’ disease) is a disease of varying severity ranging from mild febrile involvement to sometimes fatal forms of pneumonia. It is due to exposure to species Legionella.
After an incubation period of 2 to 10 days, legionellosis manifests itself as acute pulmonary infections such as pneumonia. The first symptoms resemble a flu (fever, dry cough) followed by an increase in fever which can reach 39.5 ° C. The patient then feels sensations of discomfort, as well as abdominal pain (nausea, vomiting, diarrhea), accompanied by psychological disorders (confusion, disorientation, hallucinations which can lead to delirium and coma).
The disease can progress with two types of complications: irreversible respiratory failure and acute renal failure, which are often fatal. The Legionella However, they mainly proliferate in the most fragile individuals such as immunocompromised people or weakened people (operated on, the elderly, infants).
In the whole world, Legionella pneumophila waterborne is the most common cause of infection and outbreaks. This species and related species are commonly found in lakes, rivers, streams, hot springs, and other water collections. We can find other species, like L. longbeachae in potting soil for repotting. The bacteria live and multiply in water systems at temperatures between 20 and 50 ° C (optimum temperature of 35 ° C).
The most common route of transmission of Legionella passes through inhalation of contaminated aerosols. Sources of aerosols that have been associated with this transmission are cooling towers of air conditioning systems, hot and cold water systems, air humidifiers and whirlpools.
