Title Legionnaires’ Disease Discovered in Patients at California Health Care Facility
Introduction LA Testing offers PCR and traditional culturing methods to quickly and accurately identify the pathogen that causes Legionnaires’ disease from environmental samples.

Huntington Beach, CA, June 11th, 2019

The California Department of Corrections and Rehabilitation (CDCR) reported that Legionnaires’ disease was confirmed at a California Health Care Facility (CHCF) in Stockton. CHCF provides medical care and mental health treatment to inmates who have severe and long term needs.

According to the CDCR, a patient from the CHCF recently passed away at an outside hospital and post-death analysis confirmed the presence of Legionella in the patient. In addition to the patient who tested positive in the hospital, another patient tested positive and was receiving treatment at CHCF. As the source of the Legionella bacteria that causes the disease was investigated, CHCF provided bottled water for drinking and hygienic functions, halted the use of any aerosolizing equipment, shutting down the use of showers in specific areas and provided education to both staff and patients.

Legionella is found naturally in the environment and in manmade environments, usually in water. Legionnaires' disease can occur when people breathe in small droplets of water that contain the bacteria. Past outbreaks have been associated with plumbing systems, cooling towers, hot tubs, hot water tanks and even decorative fountains.

“The presence of Legionella in California’s correction system has occurred before,” said Michael Chapman, Laboratory Manager of LA Testing’s Huntington Beach facility. “In 2015, six inmates at San Quentin State Prison were diagnosed with Legionnaires’ disease. Quickly identifying the source of the bacteria is essential for stopping these types of outbreaks. PCR test methods exist that can give results in one day, but they do not indicate if the bacteria are alive or not. It is an excellent analytical method for rapid results, but traditional culturing methods remain the gold standard and the two testing methods can be used effectively together. At LA Testing we offer these analytical services and all of the sampling supplies necessary to help protect all residents of California.”
