Health officials are investigating a deadly outbreak of Legionnaires' disease in a northern California county.
As part of its investigation, the county has been testing human-made water sources, including cooling towers and decorative fountains, for the presence of the bacteria that causes Legionnaires' disease.
"Our joint investigation team continues to work with Embassy Suites staff to remediate the source of exposure," Napa County health officer Dr.
None of the 12 patients diagnosed with Legionnaires' disease have been identified as having stayed or visited the Embassy Suites hotel, health officials said.
The person who died in the Napa County outbreak was over 50 and had risk factors for "severe disease," health officials said.
