CIV H3N2 is characterized by which statement?

CIV H3N2 is characterized by which statement?

• A. Recently found in United States. Of avian origin and spread to 30 states by April 2016. This is the dog flu most of us are hearing about today. It is NOT seasonal.
• B. A canine-origin virus that has spread to 10 states and is seasonal
• C. A feline-origin virus that is easily diagnosed
• D. A bacterial respiratory infection not related to CIV

Answer: (B)

CIV H3N2 is a canine influenza virus, so the key idea is that this infection affects dogs, can spread across multiple states, and tends to follow a seasonal pattern like other flu viruses. The statement that best fits it says it is a canine-origin virus that has spread to 10 states and is seasonal. This aligns with how CIV H3N2 behaves in the real world: it circulates among dogs across a region and shows influenza-like seasonality, which is important for prevention and outbreak planning. The other options mix in traits that don’t fit: avian origin with a much broader spread and a nonseasonal claim, feline origin, or describing a bacterial infection—none of which describe CIV H3N2 as it’s understood in this context.
