INDIANAPOLIS — The state Board of Animal Health is urging Indiana horse owners to be vigilant about making sure their animals are vaccinated against the West Nile virus.
The board says three horses already have been diagnosed with the mosquito-borne disease. That's compared with 722 cases that were reported in Indiana in 2002, the year the virus was first found in the state.
State officials say the key to keeping the number of horses infected by the virus down is the widespread use of vaccinations, as well as diligence in eliminating mosquito breeding sites.
The initial vaccination requires a series of two shots, with the second to follow within three to six weeks of the first. A booster each year continues to protect horses from infection.
