Official IBR eradication plan: There is a voluntary IBR eradication program. Herds are classified in four different categories:
Status I1 : unknown status, no controlled vaccination nor serology
Status I2 : intensive vaccination of all animals older than 8 months, repeated vaccination every 4 to 7 months
Status I3 : all animals are gE negative (two serologic controls of all the animals older than 12 months with an interval of 5 to 7 months, followed by yearly control of a selected number of animals)
Status I4 : all animals are gB negative (two serologic controls of all the animals older than 12 months with an interval of 5 to 7 months, followed by yearly control of a selected number of animals)
IBR-free certification: There are two types of IBR-free certification depending on the type of test used (gB or gE). See above the procedure to achieve IBR-free certification.
IBR herd/individual prevalence: 66% of herds contain IBR carriers, 30% of animals are gB positive.
Vaccination: Only IBR marker vaccines are allowed (live and inactivated).
