What is the primary vector for equine encephalitis?

• A. Ticks
• B. Mosquitoes
• C. Flies
• D. Rodents

Answer: (B)

Mosquitoes are the primary vector for equine encephalitis. This virus is transmitted by the bite of infected mosquitoes, which acquire it from reservoir hosts and then pass it to horses (and humans) during feeding. Ticks, flies, and rodents are not the main means of transmission for this virus, though they are relevant to other diseases. Knowing that mosquitoes drive the spread explains why mosquito control and vaccination of horses are key preventive measures.
