IBR is a highly infectious respiratory disease and while it affects animal health and productivity, it can also affect the trade of animals, semen and embryos. IBR is common worldwide, including in Ireland. However, a number of European countries have managed to eradicate the disease from their herds. In Ireland, an IBR Implementation Group is currently considering the merits of a national IBR programme.

Once an animal becomes infected with IBR, it remains infected for life, despite developing immunity.
