ARNOLD, Mo. (KMOV.com) -- A Jefferson County rec center pool has re-opened after it closed this past weekend over concerns over a Legionnaires' contamination.
The indoor pool at the Arnold Recreation Center closed last Thursday after the Missouri Health Department confirmed a St. Louis County man had visited the pool recently who was diagnosed with Legionnaires disease.
The city shut down the pool 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 rec center, 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.
The rec center re-opened Sunday morning.
