And in almost a third of those outbreaks, the infections could be traced back to hotel pools, hot tubs and spas, the CDC says.
Legionella, which causes the serious pneumonia-like illness Legionnaires’ disease, as well as the less-severe Pontiac fever, was responsible for 57 outbreaks and 624 illnesses.
Pseudomonas, which results in swimmer’s ear or a skin condition known as “hot tub rash,” caused 47 outbreaks and 920 infections.
Crypto, for example, can survive even in properly maintained and chlorinated pools, and Pseudomonas and Legionella thrive in slimy areas in hot tubs, pools and water playgrounds.
