Though, the disease is not a threat to most healthy people, it is harmful to people with a weakened immune system and the elderly.
Locations of the Bacteria
Effects of Legionella
Chances of catching the diseases
A recent research study provided evidence that Legionella , can travel airborne at least 6 km from its source.
About 8,000 to 18,000 people get Legionnaires' disease in the United States each year.
Legionella affects the host's lungs which cause the host to have problems breathing.
Person to person spread of Legionnaires' disease can not happen. This means that you can't catch Legionnaires' disease from an infected person. You cannot catch Legionnaires' disease from drinking contaminated water either. To get the disease you need to inhale water droplets that contain Legionella bacteria.
Legionnaires' disease is an uncommon cause of pneumonia.
