ARNOLD, Mo. (KMOV.com) -- A Jefferson County rec center pool that closed for a second time over concerns over a possible Legionnaires' contamination has re-opened.
The indoor pool at the Arnold Recreation Center closed January 10 after the Missouri Health Department confirmed a St. Louis County man had visited the pool recently who was diagnosed with Legionnaires disease.
Thursday, officials said a second person who had visited the rec center in recent weeks was diagnosed with Legionaire's. However, workers said the pool could not be officially connected to the diagnosis, so it re-opened over the weekend.
The city shut down the pool on Jan 10 to disinfect it with a ‘chlorine shock’ but did not drain the pool. Arnold was not required to close or disinfect the pool under Missouri health codes, but out of an abundance of caution chose to do so.
The rec center, located on Missouri State Road, did not shut-down the entire building, only the pool area.
Legionnaires’ is a type of pneumonia that is spread through mist, such as from air-conditioning units in large buildings. Adults over the age of 50 and people with weak immune systems, chronic lung disease or heavy tobacco use are most at risk of contracting the illness.
