Legionnaires' Disease

An early test found evidence of Legionella pneumophila bacteria in the water distribution system in a building in the Melrose Houses in the South Bronx. This is a separate incident from the broader South Bronx outbreak that occurred in July and August, and has been declared over by the Health Commissioner

The Commissioner’s Order issued in response to the July/August outbreak is still in effect. All owners of buildings with cooling towers must disinfect their towers and follow other requirements in the order.

What is Legionnaires’ disease?
Legionnaires’ disease (or Legionellosis) is a type of pneumonia. It is caused by bacteria (Legionella) that grow in warm water.
Is the disease contagious?
No. Legionnaires’ disease is not spread from person to person. People only get sick by breathing in water vapor containing the bacteria. People who are sick cannot make others sick.
Who is at risk?
Groups at high risk include people who are middle-aged or older—especially cigarette smokers—people with chronic lung disease or weakened immune systems and people who take medicines that weaken their immune systems (immunosuppressive drugs).
What are the symptoms of Legionnaires’ Disease?
Symptoms are like the flu and can include fever, chills, muscle aches and cough. Some people may also have headaches, fatigue, loss of appetite, confusion or diarrhea.
What should I do if I think I have Legionnaires’ disease?
If you have flu-like symptoms, seek medical attention right away, especially if you have a medical condition that affects your breathing, like emphysema, or if you are a smoker.
What is the treatment for Legionnaires’ disease?
The disease is treated with antibiotics. Most people get better with early treatment, although they may need to be hospitalized. Some people may get very sick or even die from complications of the disease. That’s why it is important to get medical help right away if you develop symptoms.
