eastern equine encephalitis
LowTechnical/Scientific
Definition
Meaning
A severe viral disease transmitted by mosquitoes that causes brain inflammation in horses and humans, primarily occurring in eastern regions of North America.
Also known as EEE or sleeping sickness in horses, this rare but often fatal arbovirus infection affects the central nervous system, with outbreaks typically following seasonal mosquito activity patterns in specific geographic areas.
Linguistics
Semantic Notes
Always used as a noun phrase; often abbreviated as EEE in medical contexts; combines geographic origin (eastern), affected species (equine), and medical condition (encephalitis).
Dialectal Variation
British vs American Usage

Terminology is identical; both varieties use the full term and abbreviation EEE equally in medical literature.
Connotations
None beyond the medical seriousness of the disease.
Frequency
More frequent in American English due to the disease's geographic prevalence, but equally recognized in British medical contexts.
