Following epidemiological tracing and increased notification, affected backyards were identified: two in Baja California. The backyards have been depopulated and cleaning and desinfection are on-going. Active surveillance continues in these States for new cases. It was recommended that producers in the area immediately inform official veterinary personnel of the presence of typical signs of rabbit haemorraghic disease or of any wild animals found dead in the area, as well as avoid movements of rabbits. |
