RIVERDALE, Utah - Weber-Morgan health officials are warning residents after mosquitoes have tested positive for West Nile Virus near Riverdale.

"These are the first mosquitoes known to test positive in Utah this year,” Amy Carter said, communicable disease nurse with the Weber-Morgan Health Department. “With the warm winter and rainy spring, we expect to see more mosquitoes than usual. In order to prevent human cases, it’s important for each person to take precaution.”

Officials said the best precautions include:

·         Using insect repellant that contains DEET (N,N-diethyl-m-toluamide).
·         Wearing long shirts and pants from dusk to dawn.
·         Remove standing water from around yards and homes.
·         Make sure windows, doors and screens fit tightly without holes.

“The mosquitoes that carry the virus are most active between dusk and dawn,” Carter said. “It’s important to keep that in mind if you are going to be outside during these hours you should always have a container of mosquito repellent handy.”

According to the Weber-Morgan Health Department, infected mosquitoes spread the virus when they bite humans, horses and birds.

Health officials said there is a vaccine for horses but no such preventive measure or treatment exists for humans.
