Legionella was first discovered in 1976 after a group at individuals attending a convention of the American Legion became ill with a type of pneumonia that was eventually attributed to Legionella bacteria. The disease was given the name of Legionnaires’ Disease. In fact, the same bacteria is responsible for Pontiac Fever, a milder form of the illness. In 2018, a record number of cases of Legionnaires’ disease were reported to the CDC (9,933 cases). CIH Services can obtain water and swab samples in your facility to determine the presence of Legionella and can recommend corrective actions if the bacteria is isolated. According to the CDC, there is no safe level of Legionella in building water systems.
