Maps showing distribution of BVD-positive births during each year of the BVD eradication programme. For the current year, a map showing the distribution of BVD-positive herds is also displayed. Each hexagon represents an area of approximately 10km2. Cells with thick blue borders have low numbers of cattle (e.g. mountainous areas, lakes, rivers, towns, cities).
