What Is Legionnaires’ Disease and How Is It Spread
Legionnaires’ disease is a form of pneumonia caused by inhaling aerosolized water contaminated with Legionella pneumophila bacteria. Symptoms—such as cough, fever, chills, muscle aches, and difficulty breathing—often appear 2 to 10 days after exposure. High-risk individuals include those over 50, smokers, and people with chronic lung or immune conditions. The illness is not spread person-to-person and can be treated effectively with antibiotics if diagnosed early.
Timeline: From Initial Detection to Rising Case Count
New York City’s outbreak was first detected on July 25, with initial reports noting 22 cases and one death. By August 4, case counts had surged to 58, and a second fatality was confirmed today. 
The outbreak has impacted ZIP codes 10027, 10030, 10035, 10037, and 10039, and includes surrounding neighborhoods. All 11 cooling towers that tested positive have since been ordered to undergo remediation within 24 hours.
