Equine Encephalomyelitisby Debora Johnson
Equine Encephalomelitis is an infectious viral disease that affects the brain of the horse. The mosquito vectors the disease from hosts: birds, reptiles and rodents. The Eastern strain is the most frequently found in the United States and has the highest mortality rate. There are two other known strains: Western and Venezuelan. This disease is also called sleeping sickness. The most prevalent time for infection is midsummer to frost. Horses can transmit the disease to one another through common food, water, and contact.
Note: "To obtain further data on the potential for snakes to harbor EEEV, Unnasch and colleagues from the Department of Biological Sciences at Auburn University in Auburn, Ala., wrangled snakes at the Tuskegee National Forest (an EEEV endemic area in east-central Alabama). The researchers collected blood samples from the snakes and tested them for antibodies (infection-fighting proteins) against EEEV and genetic material specific to EEEV by a laboratory process called quantitative reverse transcription polymerase chain reaction (qRT-PCR).
Key findings of the study were:
Generally, symptoms will start to appear after five days of infectious exposure.
Make the horse comfortable. The outcome is not usually good.
