Title Sonoma County Resident Dies after Contracting Legionnaires’ Disease
Introduction LA Testing provides analytical services and all of the sampling supplies needed to identify Legionella and other environmental pathogens.

Huntington Beach, CA, February 2nd, 2018

Recently, the Press Democrat published a story about the death of a Sonoma County woman who had been diagnosed with Legionnaires’ disease. According to the report, there have been other cases of the severe form of pneumonia in the county, but it was the first recorded death in the area for 2017.

Legionnaires' disease is caused by a type of bacteria known as Legionella. Symptoms usually begin 2 to 14 days after exposure. Legionnaires' disease can have symptoms similar to other forms of pneumonia, making it hard to diagnose. Signs of the disease may include a high fever, chills and coughing. In addition, some people may also suffer from muscle aches and headaches. Chest x-rays are often needed to find the pneumonia caused by the bacteria.

According to the Centers for Disease Control and Prevention (CDC), “Each year, between 8,000 and 18,000 people are hospitalized with Legionnaires' disease in the U.S. However, many infections are not diagnosed or reported, so this number may be higher.” There is a 5% to 30% of mortality rate for those infected.

“This is not the only time Legionnaires’ disease recently made the news in California, late last year, there was an outbreak in Orange County,” said Michael Chapman, Laboratory Manager at LA Testing’s Huntington Beach facility. “Legionella is found naturally in the environment and can also be present in manmade environments, usually in water. Legionnaires' disease can occur if 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.”

To help prevent new cases of Legionnaires’ disease or to pinpoint the source of an existing outbreak, LA Testing offers environmental Legionella testing services and all of the supplies necessary to submit samples. Both rapid PCR and traditional culturing methods are available.
