    Why We Vaccinate - Eastern & Western Equine Encephalitis (“Sleeping Sickness”)


    Burwash Equine Services .... Eastern Equine Encephalitis (EEE) and Western Equine Encephalitis (WEE) are both neurological diseases spread to horses and humans from infected wild birds and rodents via blood sucking mosquitos. Circulating levels of the virus in an affected horse are low, however, so it is highly unlikely that a horse would be a source of infection for a human. In horses, both EEE and WEE viruses can cause fever, depression, incoordination, staggering and blindness <more>
