Which viral family is responsible for Malignant Catarrhal Fever, and what is a typical presentation?

Malignant catarrhal fever is caused by a herpesvirus in the family Herpesviridae, most often the Ovine herpesvirus 2. This virus leads to a fatal disease in cattle and other ruminants, typically after exposure to persistently infected small ruminants. The classic presentation includes marked depression with mucosal involvement, producing oral and nasal discharge, along with dyspnea. Eye involvement is common, with keratoconjunctivitis and corneal opacity. This combination of systemic illness, mucosal discharge, respiratory signs, and eye clouding is characteristic and helps distinguish it from diseases caused by other viral families, which tend to present with different patterns such as primarily respiratory symptoms without the same mucosal/ocular involvement, fever with jaundice, or diarrhea.
