Which of the following is not listed as a method to control zoonosis of the Eastern Equine Encephalitis viruses?

• A. Bird control
• B. Mosquito control
• C. Vaccinate horses
• D. Quarantine of dogs

Answer: (D)

The question tests how to reduce transmission of a vector-borne zoonosis like Eastern Equine Encephalitis. The virus cycles mainly between birds and mosquitoes, with horses serving as amplification hosts and humans as incidental, dead‑end hosts. So the tools that actually cut spread are those that reduce the mosquito population or interrupt transmission in horses. Mosquito control lowers the bite rate and virus circulation in the vector, while vaccinating horses decreases the number of infected horses that can amplify the virus in the environment, reducing spillover risk to people. Quarantine of dogs doesn’t fit because dogs are not part of the virus’s transmission cycle and quarantining them would not impact the spread of the disease.
