The source of the outbreak was traced to the air-conditioning cooling towers on the nursing homes roof.In an outbreak in lower Quebec City, Canada, 180 people were affected with 13 resulting deaths  due to contaminated water in a cooling tower.In November 2014, 302 people were hospitalized following an outbreak of legionellosis in Portugal, and seven related deaths were reported. All cases emerged in three civil parishes from the municipality of Vila Franca de Xira in the northern outskirts of Lisbon, and were treated in hospitals of the greater Lisbon area. The source is suspected to be located in the cooling towers of the fertilizer plant Fertibéria.Twelve people were diagnosed with the disease in an outbreak in the Bronx, New York, in December 2014; the source was traced to contaminated cooling towers at a housing development. In July and August 2015, another, unrelated outbreak in the Bronx killed 12 people and made about 120 people sick; the cases arose from a cooling tower on top of a hotel. At the end of September, another person died of the disease and 13 were sickened in yet another unrelated outbreak in the Bronx.
The contaminated droplets likely spread to the people in and beyond the park.In July 2019, 11 former guests of the Sheraton Atlanta hotel were diagnosed with the disease, with 55 additional probable cases.In September 2019, 141 visitors to the Western North Carolina Mountain State Fair were diagnosed with Legionnaires disease, with four reported deaths, after a hot tub exhibit is suspected to have developed and spread the bacteria. At least one additional exposure apparently occurred during the Asheville Quilt Show that took place a few weeks after the fair in the same building where the hot tub exhibit was held. The building had been sanitized after the outbreak.In December 2019, the government of Western Australias Department of Health was notified of four cases of Legionnaires disease.
