Encephalitis loss of appetite depression Altered gaits Partial paralysis Fever impaired vision head pressing aimless wandering Inability to swallow Weakness of the hind limbs coma death Reference: “West Nile Virus Guidelines for Horse Owners."

Eastern Equine Encephalitis Virus Bacteria Leaning for stability Brain Hemorage due to Inflammation
9
Vaccination administered by a veterinarian. Limit exposure House horses indoors during peak periods of mosquito activity Avoid lights inside stable during evening and overnight Topical preparations containing mosquito repellants Reference: "West Nile Virus Guidelines for Horse Owners."
10
Viruses in horses interest me because horses are amazing animals and such a high percentage fatality rate in horses infected Approximately 33% of horses exhibiting clinical signs will die Approximately 40% will have residual neurologic deficits after recovering Reference: "West Nile Virus."
11
potential introduction and monitor the spread of the West Nile Virus in Guadeloupe In 2002, antibodies to WNV were detected in horses in Mexico and Guadeloupe report and discuss the temporal evolution of WNV circulation in Guadeloupe, in hopes to increase understanding of WNV epidemiology in the Neotropics.
12
July 2002, sera from 360 horses was collected December 2002, sera from 136 horses was collected from study sites where WNV was detected In 2005, survey was taken at 7 sites with high risk for WNV with 106 seronegative equines were sampled and monitored every 6 months for seroconversion.

Conducted to look for confirmation of an acute infection Active surveillance represents the best WNV surveillance system WNV is difficult to diagnose due to the unspecific clinical signs
16
1084 horse sera samples were tested for IgM WNV antibodies Total of 12 tested positive resulting in an 0.7% seroprevalence rate.
17
Additionally, 1472 sera samples were tested for the presence of IgG WNV antibodies Total of 128 tested positive resulting in an 8.7% seroprevalence rate Criteria for selected horses was that they were not moved in the international transport nor moved between counties, ages were from 6 months to over 25 years, and had no WNV vaccination history
