Malignant Catarrhal Fever (MCF) or Bovine Malignant Catarrh are actually two diseases caused by separate herpes viruses that are almost always fatal to cattle, deer, bison, occasionally pigs, rabbits, and certain exotic ruminants. Neither virus causes disease in their principal hosts, either the wildebeest or the sheep.

Feline Herpesvirus (FHV-1), also known as Feline Viral Rhinotracheitis (FVR), is an important cause of upper respiratory disease (URD) and eye inflammation in cats and other members of the cat family worldwide. FHV-1 is an alphaherpesvirus which contains double-stranded DNA.

It is likely that most cats will be exposed to the infection during their lifetime. There is only one serotype of the virus and all isolates are genetically similar.
