    The study analyzed 1001 plasma samples to assess Legionella antibody seroprevalence in Northeastern Australia from 2016 to 2023.

  • 2

    Total Legionella seroprevalence remained stable at approximately 32% between 2016 and 2023, despite changes in specific species.

  • 3

    L. pneumophila seroprevalence decreased, while L. longbeachae seropositivity increased, indicating shifting trends in Legionella infections.

  • 4

    Higher rainfall and specific land cover types were positively associated with seropositivity for certain Legionella species.

  • 5

    The study emphasizes the need to assess Legionella exposure risks, particularly for vulnerable populations in high-risk areas.
