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.
