The source of the outbreak has been traced to the hotel’s cooling tower, the Georgia Department of Public Health now says.
Public health officials also traced the Legionella bacteria to a decorative fountain in the atrium.
In a statement, the agency said remediation to the entire hotel water distribution system, including the cooling tower and decorative fountain has been made and sampling and testing will continue at the hotel.
Following a complete inspection, the hotel was cleared to open Thursday. It will begin taking additional reservations on Friday.
In a statement Thursday, the hotel said it closed voluntarily on July 15, and for the past month has worked closely with public health officials.
There have been 13 lab-confirmed cases ”of Legionnaires’ disease, including one death, and 66 probable cases of Legionnaires’ disease related to this outbreak, according to the department.
What is Legionnaires’ disease?
Symptoms can include coughing, shortness of breath, high fever, muscle aches and headaches, and can begin two to 10 days following exposure to the bacteria.
It usually isn’t spread from person to person. Because the bacteria often live in warm water, people usually come down with it after being exposed to faucets, showers, bath tubs, and fountains where the germs may have been.
The CDC says about 1 in 10 human cases prove fatal.
Nationwide, the number of cases has risen 550% since 2000, with 7,500 US cases in 2017. Those statistics are due in part to a true rise in the number of actual cases, but also a rise in reporting cases.
