Eastern Equine Encephalitis Virus

Locally Acquired Eastern Equine Encephalitis Virus Disease, Arkansas, USA

To the Editor: Eastern equine encephalitis virus (EEEV) is an arbovirus (family Togaviridae, genus Alphavirus) transmitted to humans primarily from Aedes, Coquillettidia, and Culex mosquitoes. EEEV is maintained in a transmission cycle between Culiseta melanura mosquitoes and birds in freshwater hardwood swamps (1). Affected humans and horses are considered to be dead-end hosts; that is, they u...

Eco-Epidemiology of Eastern Equine Encephalitis Virus

Eastern Equine Encephalitis virus (EEEV; family Togaviridae, genus Alphavirus) a highly pathogenic mosquito-borne virus is endemic to eastern North America. The ecology of EEEV in Florida differs from that in other parts of the USA. EEEV in the Northeastern USA is historically associated with freshwater wetlands; however no formal test of habitat associations of EEE in Florida has been reported...

Antigenic Variants of Eastern Equine Encephalitis Virus

A study by hemagglutination-inhibition test showed that 19 strains of eastern equine encephalitis virus grouped themselves in two main types, which have been designated North American and South American. The former consists of ten strains from the eastern half of the United States, from Massachusetts to Florida; Jamaica, the Dominican Republic, and, subject to confirmation, Thailand. The South ...

Noncytopathic replication of Venezuelan equine encephalitis virus and eastern equine encephalitis virus replicons in Mammalian cells.

Venezuelan equine encephalitis (VEE) and eastern equine encephalitis (EEE) viruses are important, naturally emerging zoonotic viruses. They are significant human and equine pathogens which still pose a serious public health threat. Both VEE and EEE cause chronic infection in mosquitoes and persistent or chronic infection in mosquito-derived cell lines. In contrast, vertebrate hosts infected wit...
