State Veterinarian, Dr. Keith Roehr said strict insect control is an important factor to inhibit the transmission and spread of West Nile Virus. He encouraged livestock owners to keep an eye out for standing water for mosquito populations. Roehr Recommendations also include keeping animals inside during the bugs' feeding times, which are typically early in the morning and evening, and using mosquito repellents.

The State Veterinarian's office said vaccines in horses have proven to be a very effective prevention tool. Horses that have been vaccinated in past years need an annual booster shot. If an owner did not vaccinate their animal in previous years, the horse will need the two-shot vaccination series within a three to four-week period.
