Sejong City Conducts Intensive Inspection for Legionella Bacteria Linked to Influenza and Pneumonia Symptoms

Legionnaires' Disease Prevention Inspection
Completed at 15 Multi-Use Facilities for Summer

The inspection to prevent Legionnaires' disease at multi-use facilities operating in Sejong City has been completed as of July 24.

According to academic sources, Legionella bacteria are classified as a third-grade notifiable infectious disease and thrive in warm temperatures. They usually infect people through the respiratory tract by contaminating water used in air conditioner cooling towers, water supply facilities, and public baths. Infected individuals may exhibit symptoms similar to influenza, such as Pontiac fever, or develop pneumonia, requiring careful attention.

From June 30, the city health authorities collected Legionella samples from 15 locations, including general hospitals, nursing hospitals, large buildings, and fountains, over four rounds of inspection. The samples were sent to the Institute of Health and Environment for testing. As a result, no Legionella bacteria were detected in any of the samples.

In particular, facility managers of multi-use establishments were provided with guidelines on managing Legionnaires' disease for each facility and equipment type, and were instructed to consistently maintain a clean environment. If Legionella bacteria are detected in the future, the relevant facility will undergo thorough cleaning and disinfection, and a re-inspection will be conducted in cooperation with the Institute of Health and Environment to ensure strict hygiene management.

A public health center official stated, "Although Legionella bacteria were not detected in the inspections, it is important to continuously maintain a hygienic environment," and added, "We will do our best in infectious disease prevention and hygiene management so that citizens can have a safe summer."
