Wellboat visits before suspicion

The 28 days before the case started (suspected 19 Jul 2024). Each mark is one visit. A filled triangle means the boat had, in the previous 14 days, been at another farm with an active ISA or PD outbreak. An open triangle means it had only been at farms in a protection zone, with no outbreak there. Visits after suspicion are not included.

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