Big buildings, hot tubs and warm weather might have led to the conditions that resulted in several local cases of Legionnaires’ disease, medical and building experts said.

A day after news broke of four cases of Legionnaires’ disease tied to two LA Fitness gyms in Orlando, Lake County health officials confirmed a seniors community in Clermont is also being investigated.

Health investigators are also focusing on hot tubs, which may help spread the deadly bacteria, at the Summit Greens community in Clermont….

Buildings with large water systems can be susceptible to Legionella growth and hot tubs can help spread bacteria, said Bill Pearson, senior vice president of Special Pathogens Laboratory in Pittsburgh.

“When the bacteria is able to find favorable conditions to multiply, it becomes a health hazard,” he said.
