Summary of serology results.

Results are reported at the serogroup level. Human studies include both clinical and seroprevalence studies, while animal studies are seroprevalence only. A specific serogroup is reported as present in a PI if it was reported from at least one study over the 1947–2017 period, meaning that studies classified as ‘weak evidence’ for leptospirosis were also included. For this reason, and because of the limitations of the MAT, results should be interpreted with caution.
