The visitors were not at the resort at the same time and were not connected, he told WMUR. The New Hampshire Department of Health and Human Services confirmed to the station that they had stayed at the resort, but noted the investigation into how and where the two contracted the disease. The investigation is looking into the resort’s water systems, and Chan said the resort’s hot tub was shut down. Legionella bacteria cause a serious type of pneumonia, Legionnaires Disease, as well as Pontiac Fever, according to the Centers of Disease Control and Prevention. Symptoms, such as a cough, shortness of breath, fever, muscle aches and headaches, can start two days to two weeks after exposure, and can even take longer, the CDC said. The bacteria grows and spreads in human-made building water systems. This includes showerheads and faucets, hot tubs, decorative fountains, hot water tanks and heaters, and in large, complex water systems. Typically, Legionnaire’s Disease is not spread through contact with other people, the CDC said.
