[TD]- Tunisia is located in the main migratory corridor for wild birds going to Africa from Europe during winter migration. Migration is ongoing and this viral strain must have been carried over by migrating birds. - According to the OIE Terrestrial Animal Health Code, article 10.4.1, provision 8, this outbreak does not modify the sanitary status of the country as affected birds are wild and thus are not included in the OIE definition of poultry. - A 3-km protection zone and a 10-km surveillance zone were implemented. There is no industrial poultry farm within the protection zone, and eight broiler farms within the surveillance zone. - Surveillance measures strengthened within the surveillance zone and the whole country. - Access to Ichkeul Natural Park was suspended.[/TD]
