Drift simulations: backward simulations in the Balearic Islands area (orange path), forward simulations at L’Ametlla de Mar area (blue path) and, forward simulations at the north Catalonia area (purple path). Note that points at the end of the paths indicate the particle final position. Simulations were inferred between point 1 (p1; infected point) and point 2 (p2; no signs of infection at the beginning of the simulation and infection at a known time interval of the simulation). The rectangle indicates 650 km2 buffer zone around a given point.
