What is Eastern Equine Encephalitis?

The Tennessee Department of Agriculture recently confirmed a case of Eastern Equine Encephalitis (EEE) in west Tennessee.  Eastern and Western Encephalitis and West Nile Virus are transmitted by mosquitoes and, in rare instances, other bloodsucking insects.  Of these, EEE is the most virulent in horses, causing a mortality rate of up to 90%.   EEE is found in eastern, southeastern, and southern states, but risk exposure varies depending on the distribution of insect vectors (mosquitoes) and virus reservoirs (wild birds and rodents).


How do I protect my horse?

We recommend vaccinating every six months with our 5-way vaccine, which includes Eastern and Western Encephalomyelitis, as well as tetanus, rhinopneumonitis, and influenza.  Additional precautions can be put in place to control the mosquito population in your area, including removing standing water and using appropriate repellents.
