What is the Legionnaires' Disease?

July 29, 2025

Residents of Central Harlem in New York City have been advised to exercise caution after cases of Legionnaires' disease have been identified recently, prompting health authorities to launch an urgent investigation.

About Legionnaires' Disease:

  • It is a severe form of a lung infection called pneumonia.
  • It is caused by a bacterium known as legionella.
  • Transmission:
    • Legionella is found naturally in freshwater, such as lakes and rivers. It can also be found in soil.
    • Most people who catch Legionnaires' disease breathe in the bacteria from water or soil.
    • You usually can't get infected by drinking water that contains the bacteria unless you aspirate it (accidentally breathe the water into your lungs).
    • It is not contagious, meaning it is not spread from person to person.
  • Older adults, people with weakened immune systems, and people who smoke have a higher risk of getting Legionnaires' disease.
  • Symptoms:
    • The main symptoms are fever, chills, headache, malaise, and muscle pain (myalgia).
    • Untreated Legionnaires' disease can kill.
  • Treatment:
    • Treating right away with antibiotics most often cures Legionnaires' disease.
    • But some people still have problems after treatment.
