Legionella Conference

Prevention of Disease and Injury From Waterborne Pathogens in Health Care


After careful consideration, NSF Health Sciences has canceled the 2022 Annual Legionella Conference.

Due to the ongoing COVID-19 pandemic and acceleration of infection and transmissibility of coronavirus variants, such as the Delta variant, there is too much uncertainty for us to execute plans for a safe, in-person event.

The Annual Legionella Conference has been a successful partnership for several years, sharing innovative and vital information with the public health and safety community.

NSF remains committed to supporting this large public and private community in the prevention of waterborne pathogens and the pursuit of public health.

At this time, NSF will continue to focus on its core business strategies, including localized training, risk assessments and water management plan development for building owners and managers.

We ask for your understanding and thank you for your past participation in one of the largest Legionella conferences in North America.
