Two Community Clusters of Legionnaires’ Disease Directly Linked to a Biologic Wastewater Treatment Plant, the Netherlands

摘要

A biologic wastewater treatment plant was identified as a common source for 2 consecutive Legionnaires’ disease clusters in the Netherlands in 2016 and 2017. Sequence typing and transmission modeling indicated direct and long-distance transmission of Legionella , indicating this source type should also be investigated in sporadic Legionnaires’ disease cases.
