Recent cases of Legionnaires' disease have been reported in Central Harlem, New York City, prompting local health authorities to issue a public health advisory.

What is Legionnaires' Disease?

Legionnaires' disease is a severe form of pneumonia, an infection that affects the lungs and can be fatal if not treated promptly. The disease is caused by the bacterium Legionella, which thrives in freshwater environments such as lakes, rivers, and soil.

Transmission of Legionnaires' Disease

  • Legionella bacteria are found naturally in water sources and can contaminate water systems like cooling towers, hot tubs, or plumbing systems.

  • Inhalation of aerosolized water containing Legionella bacteria is the primary means of infection. People usually breathe in the bacteria when it is dispersed in small droplets, such as those from a shower, air conditioning units, or humidifiers.

  • Drinking contaminated water doesn’t generally lead to infection unless the water is accidentally aspirated (inhaled into the lungs).

  • Legionnaires' disease is not contagious, meaning it cannot be transmitted directly from person to person.

Symptoms of Legionnaires' Disease

Common symptoms of Legionnaires' disease include:

  • Fever and chills

  • Headache

  • Malaise (a general feeling of illness or discomfort)

  • Muscle pain (myalgia)

If left untreated, the disease can progress to more severe symptoms, such as:

  • Severe pneumonia

  • Respiratory failure

  • Organ failure

In severe cases, Legionnaires' disease can be fatal. Therefore, early detection and treatment are essential.

Risk Factors for Legionnaires' Disease

Certain groups of people are at a higher risk of contracting Legionnaires' disease:

  • Older adults, especially those over the age of 50

  • Individuals with weakened immune systems (such as those with HIV/AIDS, undergoing chemotherapy, or taking immunosuppressive drugs)

  • People who smoke or have a history of smoking

  • Those with chronic lung diseases (like COPD)

These individuals may have a harder time fighting off infections, making them more vulnerable to complications from Legionnaires' disease.

Treatment of Legionnaires' Disease

  • Antibiotics are the primary treatment for Legionnaires' disease. When treated promptly, the disease can usually be cured with antibiotics, such as macrolides (azithromycin) or fluoroquinolones (levofloxacin).

  • However, even with treatment, some individuals may still experience lingering symptoms, such as fatigue and breathing difficulties, after recovery.

Precautions and Preventive Measures

To avoid Legionnaires' disease, it's important to maintain and clean water systems, especially in large buildings, where water sources like cooling towers or humidifiers can harbor Legionella bacteria. Regular inspections, cleaning, and disinfection of plumbing and cooling systems can help reduce the risk of contamination.
