Respiratory disease outbreak in a veterinary hospital associated with canine parainfluenza virus infection.

A cluster of canine parainfluenza virus infections was identified in a veterinary referral hospital. While hospital-associated outbreaks of canine parainfluenza virus infection have not been previously reported, veterinary hospitals possess some of the same risk factors that may be present in traditional high-risk sites such as kennels. Hospital-associated transmission of canine respiratory pathogens, therefore, must be considered.
