An Introduction to Eastern Equine Encephalitis
Eastern
equine encephalitis is a rare disease that is spread to horses and humans by infected
mosquitoes. It is one of several mosquito-borne viral diseases that can affect the central nervous system and cause severe complications, including death.
Eastern equine
encephalitis is found mainly along the eastern seaboard of the United States and on the eastern Gulf Coast. Currently, there is no specific treatment for eastern equine encephalitis; caregivers focus on relieving the symptoms. Prevention of eastern equine encephalitis centers on controlling mosquitoes and avoiding mosquito bites.
Eastern equine encephalitis is among the most serious of a group of mosquito-borne viral diseases. Other similar diseases include:
Eastern Equine Encephalitis Virus
Eastern equine encephalitis is caused by the eastern equine encephalitis virus, an arbovirus. Arbovirus is short for
arthropod-
borne
virus.
Arboviruses are viruses that are spread by certain invertebrate animals (arthropods), most commonly blood-sucking insects. In the United States, arboviruses are spread mainly by infected mosquitoes. Birds are the source of infection for mosquitoes, which can sometimes transmit the infection to horses, other animals, and, in rare cases, people.
