What Is The Driver Of The Legionella Risk Management Market?

The increasing concerns over waterborne diseases are expected to propel the growth of the Legionella risk management market going forward. Waterborne diseases refer to infections caused by pathogenic microorganisms transmitted through contaminated water, with Legionnaires’ disease being a severe form caused by Legionella bacteria. Concerns over waterborne diseases are rising due to aging water infrastructure that increases the risk of bacterial contamination. Legionella risk management aids in waterborne disease management by ensuring proactive monitoring and control of bacterial contamination, making it essential for buildings with complex water systems. It enhances public safety by preventing Legionella growth, reducing outbreak risks, and improving overall water quality management. For instance, in September 2025, according to the World Health Organization, a Switzerland-based intergovernmental organization, 60 countries reported more than 560,000 cases and over 6,000 deaths in 2024, marking a slight increase in reported cases and a notable rise in deaths compared with 2023. Therefore, the increasing concerns over waterborne diseases is driving the growth of the Legionella risk management industry.
