The bacteria grow best in warm water, like the kind found in hot tubs, hot water tanks and large plumbing systems common in office buildings, schools, hotels and hospitals. Most people are exposed to legionella regularly and do not contract legionellosis. People with weak immune systems are more susceptible to legionellosis. According to the CDC, most cases of legionellosis can be treated successfully with antibiotics."
