Legionnaires' Disease Outbreak in New York City
Legionnaires' disease is a serious lung infection caused by bacteria called Legionella.
It's not very common, but it can be severe, especially for older adults and people with weak immune systems.
The bacteria live in freshwater and can grow in man-made water systems like cooling towers, hot tubs, and decorative fountains.
People get sick by breathing in tiny water droplets with the bacteria.
Symptoms include high fever, cough, shortness of breath, muscle aches, headache, fatigue, chest pain, digestive problems, and confusion.
The disease can be prevented by keeping water systems clean and well-maintained.
In New York City, there has been an outbreak with 76 cases and 4 deaths, mostly in the Upper East Side.
