A sanitation programme for stamping-out viral haemorrhagic septicaemia (VHS) was implemented in Denmark in 1965. The programme has resulted in a dramatic reduction in the number of infected rainbow trout farms, from approximate to 400 to 26. The programme is carried out on a voluntary basis at the expense of the involved fish farm owners. The fact that financial support for the eradication of VHS and IHN may be made available from the European Union may enhance the efforts towards further eradication of the disease in Europe. The finding of a VHS virus (VHSV)-like virus in the marine environment is a matter of major concern, but improved diagnostic procedures may enable discrimination between the highly pathogenic freshwater strains and the apparently less virulent marine strains.
