FIG 1: — BRSV classification. Geographical distribution of herds classified as positive and negative for BRSV infection in Norway. The classification was based on an examination of antibodies against BRSV in the serum of an average of five calves without maternal antibodies in each herd in two samplings at approximately six months apart. If one or more of the sampled animals were positive for antibodies against BRSV, the herd was classified as positive (ArcGIS 10, ESRI Inc., Redlands, California, USA)
