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.
