==Treatment and Control==
Once a herd’s status has been established, BVDV control measures can be implemented. Previously, PI animals have been used as natural “vaccinators” to increase herd immunity, although naïve animals must endure acute infection before this is achieved. Eradication by identification and culling of PI animals is possible, having been successfully accomplished in Scandinavia. However, this gives many seronegative, susceptible animals- an imperfect solution for those units not completely biosecure or highly committed to the scheme. Killed and live vaccines afford a good level of protection providing they are used correctly and boosted regularly. A combination of eradication and vaccination gives the best level of control (Brownlie et. al, 2000), and the development of “marker” vaccines that allow natural- and vaccine-induced immunity to be distinguished will help this cause in future.
