Wellboat visits before suspicion

The 28 days before the case started (suspected 26 May 2026). 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.
