Final answer:
Legionnaires' disease is spread through inhalation of water droplets contaminated with the Legionella bacteria. It is not contagious and cannot be spread from person to person.
Step-by-step explanation:
Legionnaires' disease is a severe form of pneumonia caused by the bacterium Legionella pneumophila. It is typically spread through inhalation of water droplets contaminated with the bacteria. Common sources of Legionella contamination include hot tubs, cooling towers, plumbing systems, and large air conditioning units. The bacteria can multiply and thrive in warm water environments and can then be released into the air in fine droplets, which can be inhaled by people nearby.
Once inhaled, the bacteria can infect the respiratory system and cause symptoms such as high fever, cough, chest pain, and shortness of breath. Legionnaires' disease is not contagious and cannot be spread from person to person. It is important to note that not everyone who is exposed to the bacteria will develop the disease. Certain factors, such as age, smoking, weakened immune system, and underlying health conditions, can increase the risk of developing Legionnaires' disease.
