State officials in New Mexico are urging horse owners to vaccinate their horses against West Nile Virus. The New Mexico Department of Agriculture, in conjunction with the New Mexico Department of Health and the New Mexico Livestock Board, is advising equine owners to seek vaccination guidance from their veterinarians. Alongside West Nile virus, other mosquito-borne diseases such as Eastern and Western Equine Encephalitis present significant health threats to horses.
Horses may contract these viruses through mosquito bites. Though some infected horses may be asymptomatic, others could develop severe neurological illnesses, with severe cases potentially resulting in death. Symptoms can include fever, stumbling, muscle tremors, and altered behavior.
“Vaccinating horses against West Nile virus is one of the most effective steps owners can take to protect their animals during mosquito season,” stated Dr. Samantha Holeck, New Mexico State Veterinarian. “Prevention through vaccination is far safer – and often less costly – than trying to treat the horse after infection.”
In the year 2023, New Mexico recorded 19 confirmed cases of West Nile Virus among horses, with six of these cases resulting in fatalities. The American Association of Equine Practitioners categorizes West Nile virus vaccination as a core vaccine for horses.
