Transboundary Emerging and Exotic Animal Disease/ Exotic Animal Disease Practice Exam

Which strain of canine influenza was associated with clinical cases of respiratory disease in cats during outbreaks?

1. The outbreaks caused by H5N1

2. The outbreaks caused by H3N8

3. The outbreaks caused by H1N1

4. The outbreaks caused by H3N2

The correct answer is: The outbreaks caused by H3N2

The strain of canine influenza associated with clinical cases of respiratory disease in cats during outbreaks is H3N2. This strain not only affects dogs but has also shown the capability to infect cats, leading to respiratory symptoms in these animals. The H3N2 avian influenza variant is known for its adaptability and transmission potential between different species, making it a significant concern in the study of transboundary and emerging diseases. Understanding the impact of H3N2 is essential, particularly in the context of animal health surveillance and management, as it highlights the need for vigilance in monitoring diseases that may cross species barriers. Other strains such as H5N1 and H1N1 are primarily associated with birds and humans, respectively, and H3N8 is largely recognized for its effect on dogs but has not been implicated in feline respiratory disease during outbreaks. Thus, H3N2 stands out in the context of respiratory illness among both dogs and cats during these infectious disease events.
