Warmer weather means the threat of West Nile Virus is growing near. Livestock owners are being encouraged to vaccinate their horses against the disease this month. Veterinarians say it's better to get the vaccinations now, before mosquitoes become active.
There was a nationwide outbreak of the disease last summer. Officials reported 800 cases in horses and mules in Kansas last year.
Symptoms in horses include hyperactivity, depression, failure to respond, staggering and convulsions. About 30 percent of the cases are fatal.
The vaccine requires two doses over the course of three weeks.
