The Venezuelan equine encephalomyelitis (VEE) is one the most serious viral infections of the nervous system. It has a wide geographic distribution and may give rise to sequela like mental retardation, amnesia, abortion, epilepsy and hidroanencephaly in infected humans and animals. The pathology of this infection is focused mainly in two tissues: lymphohematopoietic and nervous. The VEE virus has a special cytopathic activity on the nervous cells (glia and neurons) while the lesions produced in the myelin are probably a consequence of the immunological response of the host to the infection. The alterations produced by the VEE virus in different neuronal types can originate changes in the brain concentrations of several neurotransmitters and their receptors. Some biochemical modifications that have also been reported could be due to the cytopathic effect of the virus.

UI MeSH Term Description Entries
D004685 Encephalomyelitis, Venezuelan Equine A form of arboviral encephalitis endemic to Central America and the northern latitudes of South America. The causative organism (ENCEPHALITIS VIRUS, VENEZUELAN EQUINE) is transmitted to humans and horses via the bite of several mosquito species. Human viral infection may be asymptomatic or remain restricted to a mild influenza-like illness. Encephalitis, usually not severe, occurs in a small percentage of cases and may rarely feature SEIZURES and COMA.
