Horse owners are urged to check with their veterinarian to make sure their animals have received current vaccinations and booster shots against WNV and EEE, and that these shots are kept up to date.

There are ongoing efforts to keep the mosquito populations down, but because there is no foolproof method to prevent the diseases, vaccinations are critical.
