Canine influenza virus (CIV) infection can lead to a range of health consequences in dogs, from mild symptoms to severe illness. Here’s a breakdown of the possible outcomes:
🐶 Common Symptoms
- Persistent cough (lasting 1–3 weeks)
- Runny nose and eye discharge
- Sneezing
- Fever
- Lethargy
- Loss of appetite
⚠️ Severe Complications
- Pneumonia: Some dogs develop serious lung infections, especially if secondary bacterial infections occur.
- High fever: Temperatures can spike to 104–106°F in severe cases.
- Secondary bacterial infections: These can worsen the illness and increase the risk of pneumonia.
- Death: Although rare, the mortality rate is estimated at 1–5%.
🧪 Asymptomatic Spread
- Around 20% of infected dogs show no symptoms but can still shed the virus and infect others.
🏥 Recovery and Contagion
- Most dogs recover within 2–3 weeks, but they can remain contagious for up to 4 weeks after exposure.
- Dogs are most contagious 2–4 days after infection, often before symptoms appear.
🐾 Risk Factors
- Dogs in close-contact environments (e.g., kennels, shelters, dog parks) are at higher risk.
- Unvaccinated dogs are more vulnerable to outbreaks.
