What type of illness is Legionella associated with?

Legionella is primarily known for causing respiratory illnesses, most notably Legionnaires' disease, which is a severe form of pneumonia. This bacterium is typically found in water systems, such as hot tubs, showers, and large plumbing systems, and it can be inhaled through aerosolized water droplets. When inhaled, the bacteria can lead to symptoms like cough, shortness of breath, fever, and muscle aches, all characteristic of respiratory illnesses. Thus, understanding the association of Legionella with the respiratory system is crucial for effective prevention and control measures, especially in environments where water systems are present.
