A contagious viral disease with no known cure affects animals with high fever, reddened eyes, nasal and ocular discharge; later stages involve the central nervous system with seizures and death. Euthanasia is often chosen. Which disease is described?

• A. Rabies
• B. Parvovirus
• C. Canine influenza
• D. Distemper

Answer: (D)

This describes canine distemper. It’s a highly contagious viral infection that starts with systemic signs such as fever and eye/nose discharge and conjunctivitis, which fits the reddened eyes and nasal/ocular discharge. As it progresses, the virus can affect the central nervous system, leading to seizures and death. Since there’s no cure, treatment is supportive and prognosis is often poor, with euthanasia commonly chosen in severe cases. Other options don’t fit the full pattern: parvovirus mainly causes severe vomiting and diarrhea with dehydration; canine influenza is primarily a respiratory illness; rabies involves CNS symptoms but presents with different early signs (behaviors changes, hydrophobia) rather than the described ocular/nasal discharge pattern.
