Wellboat visits before suspicion

The 28 days before the case started (suspected 21 Feb 2024). Each mark is one visit. A triangle means the boat had, in the previous 14 days, been at another farm with active ISA or PD, or in a protection zone. Visits after suspicion are not included.

VisitCame from a farm with ISA/PDPrevious farm unknown (no recorded stop in 14 days)

The Food Safety Authority's disease register starts on 26 Nov 2024. For visits before then, "came from a farm with ISA/PD" may be missing, because older cases are only included if they were still open then.
