Bears
ICH: transmission

shed in urine, 6-9 months post recovery
ICH: replication sites
Macrophages, Kupffer cells, hepatocytes, vascular endothelium
ICH: major organ targets

nasal discharge, rhinitis
severe pneumonia
ITB: diagnosis
clinical signs, PCR, serology, virus isolation
ITB: treatment
antitussives and bronchodilators
