Legionnaires’ disease: Symptoms & Treatment

Legionnaires’ disease

Legionnaires’ disease is a type of pneumonia caused by the Legionella bacteria. The bacteria can infect the lungs and cause inflammation, leading to the accumulation of fluid and pus in the air sacs. This can make it difficult to breathe and cause severe respiratory symptoms, such as coughing, shortness of breath, and chest pain. In some cases, Legionnaires’ disease can also affect other organs and systems in the body, such as the kidneys and nervous system.

Symptoms of Legionnaires' disease

Symptoms of Legionnaires’ disease usually appear 2-14 days after exposure to the bacteria and can include:

  • High fever (often above 102°F or 39°C)
  • Chills
  • Cough, which may produce mucus or blood
  • Shortness of breath, or difficulty breathing
  • Chest pain
  • Headache, muscle pain, and fatigue
  • Nausea, vomiting, and diarrhea
  • Confusion, especially in older adults

Treatment And Prevention of Legionnaires' disease

Treatment typically involves antibiotics, such as azithromycin or levofloxacin, and supportive care, such as oxygen therapy or IV fluids.

Prevention of Legionnaires’ disease involves maintaining proper maintenance and disinfection of water systems, particularly in large buildings such as hospitals or hotels, where the risk of exposure may be higher. Regular cleaning and disinfection of hot tubs, spas, and cooling towers can also help prevent the growth and spread of Legionella bacteria.
