What is Venezuelan Equine Encephalitis?
- Venezuelan equine encephalitis virus is a mosquito borne viral pathogen that causes Venezuelan equine encephalitis or encephalomyelitis (VEE).
- VEE can affect all equine species, such as horses, donkeys and zebras.
- After infection, equines may suddenly die or show progressive central nervous system disorders. Humans also can contract this disease.
Clinical signs
- WEE viruses affect the nervous system, so affected animals will have fever, depression and changes in behaviour.
- Signs of infection may also include impaired vision, muscle twitches, circling or head pressing behaviours, the inability to swallow, paralysis and convulsions.
- For VEE, death rates are variable but can be as high as 90%.
Transmission
- The virus is transmitted to people and horses by bites from infected mosquitoes and birds during wet, summer months.
Prevention
-
Vaccines for EEE are available for horses.
-
Measures to control mosquito populations and minimize mosquito exposure will decrease chances of infection.
