Influenza C Virus in Cattle with Respiratory Disease, United States, 2016–2018

Abstract

We identified influenza C virus (ICV) in samples from US cattle with bovine respiratory disease through real-time PCR testing and sequencing. Bovine ICV isolates had high nucleotide identities (98%) with each other and were closely related to human ICV strains (95%). Further research is needed to determine bovine ICV's zoonotic potential.
