This paper describes viral diseases reported in northern ungulates and those that are a potential threat to these species. The following diseases are discussed: bovine viral diarrhoea/mucosal disease (BVD/MD), alphaherpesvirus infections, malignant catarrhal fever (MCF), poxvirus infections, parainfluenza type 3 virus infection, Alvsborg disease, foot-and-mouth disease, epizootic haemorrhage disease of deer and bluetongue disease, rabies, respiratory syncytial virus infection, adenovirus infection, hog-cholera, Aujeszky's disease and equine herpesvirus infections. There are no significant differences in antibody prevalence to BVDV among deer in habitats with high, intermediate and low density of cattle. In addition, sequence analysis from the BVDV isolated from roe deer (Capreolus capreolus) showed that this strain was unique within BVDV group I. Disrinct BVDV strains might circulate in free-ranging roe deer populations in Germany and virus transmission may be independent of domestic livestock. Similar results have been obtained in a serological survey of alpha-herpesviruses in deer in Germany. Malignant catarrhal fever was studied in fallow deer (Cervus damd) in Germany: the seroprevalence and positive PCR results detected in sheep originating from the same area as the antibody-positive deer might indicate that sheep are the main reservoir animals. Contagious ecthyma (CE) is a common disease in domestic sheep and goats caused by the orf virus. CE has been diagnosed in Rocky Mountain bighorn sheep (Ovis canadensis), mountain goats (Oreamnos americanus), Dall sheep (Ovis dalli), chamois (Rupkapra rupicapra), muskox {Ovibos moschatus) and reindeer (Rangifer tarandus). Most parainfluenza type 3 virus infections

“…Lambs infected on the mouth may transmit the infection to their mothers during suckling. Regular use of salt blocks by bighorn sheep also appears to be important in maintaining the disease (Blood, 1971). …”

“…Contagious ecthyma (soremouth) has commonly been diagnosed in domestic and bighorn sheep (Blood 1971, Campbell 1980, Samuel et al 1975. Although some biologists think this condition has minimal impacts on bighorn sheep (Blood 1971), it has been responsible for numerous deaths, primarily oflambs (Campbell 1980).…”

“…Although some biologists think this condition has minimal impacts on bighorn sheep (Blood 1971), it has been responsible for numerous deaths, primarily oflambs (Campbell 1980). A species of lungworm common to domestic sheep was responsible for deaths in a captive herd of bighorn sheep Davies 1976, 1977).…”

“…This is especially important where flying insect vectors are involved. Attractants such as salt stations should be used sparingly because they tend to concentrate use by all ungulates and increase the possibility of disease transfer (Blood 1971, Samuel et al 1975. Likewise, water sources and feeding stations should be placed so they are never used at any time by both domestic and bighorn sheep ( fig.…”
