The most current theory is a result of a recent study that suggests it is caused by a pegivirus, referred to as Theiler's disease-associated virus (TDAV). [2] Eight horses that had received prophylactic botulinum antitoxin and developed subsequent signs of Theiler's disease were subjected to a test for a viral infection based on RNA sequencing techniques.
Equine infectious anemia or equine infectious anaemia (EIA), also known by horsemen as swamp fever, is a horse disease caused by a retrovirus (Equine infectious anemia virus) and transmitted by bloodsucking insects. The virus (EIAV) is endemic in the Americas, parts of Europe, the Middle and Far East, Russia, and South Africa.
Ideally, horses that are showing symptoms should be completely quarantined. The recommended quarantined period is at least 21 days. [11] Another facet of EHV-1 control is to be aware of the potential for spreading the virus via equipment, and transmission, via human contact, between horses.
While health officials say there is no human vaccine for the mosquito-borne EEE disease, people can take precautions. What you should know. Serious viral disease EEE found in upstate NY horse.
Equine encephalosis virus (EEV) is a species of virus the Orbivirus genus, and a member of the Reoviridae family, related to African horse sickness virus (AHSV) and Bluetongue virus (BTV). [ 1 ] First described in South Africa over a hundred years ago by Arnold Theiler , EEV is the causative agent of equine encephalosis ( EE ), an arthropod ...
The virus which causes EVA was first isolated in 1953, but the disease has afflicted equine animals worldwide for centuries. It has been more common in some breeds of horses in the United States, but there is no breed "immunity". In the UK, it is a notifiable disease. [3] There is no known human hazard. [4]
Eastern equine encephalitis (EEE), also called triple E and sleeping sickness, is a viral disease caused mainly by the Eastern equine encephalitis virus (EEEV). Most infections in humans are asymptomatic, but about 5% of the time the infection progresses to severe neuroinvasive disease.
Animals may show systemic signs such as anorexia, lethargy and pyrexia (fever). Disease usually resolves within two weeks, and animals usually recover completely. [2] Cases of human infection with vesicular stomatitis virus have been described. Most of these cases have been among laboratory workers, veterinarians, and livestock handlers.
