  • Bovine viral diarrhea (BVD) is most common in young cattle (6–24 mo old). The clinical presentation can range from inapparent or subclinical infection to acute and severe enteric disease to the highly fatal mucosal disease complex characterized by profuse enteritis in association with typical mucosal lesions. BVD must be distinguished from other viral diseases that produce diarrhea and mucosal lesions. These include malignant catarrhal fever (see Malignant Catarrhal Fever), which usually is a sporadic disease in more mature cattle, bluetongue (see Bluetongue), and rinderpest (see Rinderpest), which is currently considered to be eradicated worldwide.
