At least 14 cases of Legionnaires' disease have been reported in central Florida, prompting an investigation by health officials. The Florida Department of Health informed state Sen. Carlos Guillermo Smith that the outbreak is linked to a gym, although the specific name of the gym was not disclosed. However, reports indicate that a Crunch Fitness location in Ocoee, located 12 miles west of Orlando, has had members who reported cases of the disease.

In response to the outbreak, Crunch Fitness stated that it is cooperating with the health department. The gym has closed off certain areas and is testing its pool and spa systems "out of an abundance of caution." Neither the Florida Department of Health nor Crunch Fitness provided immediate comments regarding the situation.

Legionnaires' disease is a severe form of pneumonia caused by inhaling Legionella bacteria, which can be found in small droplets of water or contaminated water entering the lungs. The bacteria are naturally present in freshwater but thrive in warm water environments. According to the Centers for Disease Control and Prevention (CDC), the disease does not spread from person to person. However, outbreaks can occur if the bacteria contaminate a building's water supply, including sources like showerheads, faucets, and hot water tanks.

The prevalence of Legionnaires' disease has increased over the past decade, peaking at 2.71 cases per 100,000 people in 2018. Cases declined during the first year of the COVID-19 pandemic but rebounded in 2021. While most individuals recover from Legionnaires' disease with antibiotic treatment, those who are immunocompromised or have chronic lung conditions may face severe complications. The CDC estimates that about 10% of individuals who contract Legionnaires' disease will die from complications, with the mortality rate rising to 25% among those infected while in healthcare facilities.
