How do you control zoonosis of the EE's?

• A. Handwashing only
• B. Fence off farms
• C. Bird control, mosquito control, vaccinate horses
• D. Use antibiotics

Answer: (C)

Controlling zoonotic arboviruses like Eastern Equine Encephalitis involves interrupting the transmission cycle at multiple points: the mosquito vectors, the reservoir birds, and the susceptible horses. The virus cycles between mosquitoes and birds, and horses can become viremic and help amplify transmission to other mosquitoes and, occasionally, to humans. By reducing mosquito populations and bites, you directly cut the main route of transmission. Vaccinating horses lowers their risk of illness and, crucially, reduces the amount of virus circulating in horses if exposure occurs, which lowers the chance that mosquitoes pick up and spread it. Managing bird populations or their habitats around stables helps limit the reservoir amplification that fuels transmission. Put together, these strategies address the key links in the cycle and provide better protection than any single measure. Handwashing alone isn’t effective against a mosquito-borne virus because transmission isn’t person-to-person. Fencing might reduce contact with people or animals but doesn’t prevent mosquitoes or birds from reaching the area. Antibiotics don’t affect viruses and won’t prevent or treat EE.
