Researchers have made a connection to areas in Connecticut that have been experiencing a higher occurrence of Legionnaires’ disease dating back to 1999 to the proximity of these locations to certain rivers and watersheds. The study, published in The Journal of Infectious Diseases, found an increased number of sporadic Legionnaires’ disease cases were related to elevated rainfall and greater stream flow. Researchers concluded that their findings confirmed a possible link between weather conditions and the incidence of Legionnaires’ disease.

Legionella is commonly found in a variety of natural and building water sources. Exposure occurs when it is aerosolized and then inhaled or aspirated by susceptible individuals. Symptoms of Legionellosis vary, including fever, chills, and coughing for Pontiac Fever to a very serious form of pneumonia with long term health effects for Legionnaires’ disease.

“EMSL Analytical, Inc. has been on the forefront of Legionella testing and works to maintain up-to-date certifications in order to provide quality Legionella analysis,” said Christopher Goulah, Ph.D., Legionella Technical Manager at EMSL Analytical, Inc. “EMSL has 20 CDC ELITE proficient Legionella laboratories within its network, which spans across the United States and Canada.”
