FARMINGTON — The Navajo Nation Veterinary and Livestock Program has confirmed two horses have been diagnosed with the West Nile Virus.

The horses are from the Hunter's Point and St. Michaels areas in Arizona.

Horses are the main animals susceptible to West Nile Virus and become infected after being bitten by infected mosquitoes.

Navajo Nation Veterinarian Scott Bender stated two horses showed neurologic signs and symptoms such as fever, head droop, loss of coordination, weakness and seizures, according to a press release from the program.

West Nile Virus cannot spread from animals to people or from person to person.

Most people infected with West Nile Virus show no symptoms or develop mild symptoms, such as fever, headaches, body aches, feeling fatigue and nausea.

To prevent the disease, people are advised to use mosquito repellent with DEET and wear long-sleeved shirts and pants when conducting activities outdoors.

Outdoor activities should also be avoided at sunrise and sunset when mosquitoes are most active.

Especially during monsoon season, pools of water or open containers holding water should be drained because mosquitoes breed in standing water.
