Distributed via the CDC Health Alert Network November 15, 2019, 1430 ET (2:30 PM ET) CDCHAN-00422 Hot tub displays at temporary events may pose a risk for Legionnaires’ disease, a type of pneumonia caused by inhaling mist containing Legionella bacteria. The Centers for Disease Control and Prevention (CDC) is alerting environmental and public health practitioners about the public health need to maintain, clean and disinfect hot tubs properly to reduce potential exposure to Legionella. This Health Advisory provides guidance for environmental and public health practitioners to minimize risk for Legionella exposure from hot tub displays at temporary events (e.g., fairs, home and garden shows, conventions). Environmental health practitioners should work with event planners and hot tub vendors to minimize the risk of Legionella exposure even if the hot tub is only for display.
