North Dakota reports first human West Nile cases of the year

A batch of mosquitoes recently tested positive for West Nile Virus in Whiteside County. "This mosquito really likes hot and dry weather, which contradicts commonly held beliefs about mosquitoes", Hagston said. Birds pass the virus to mosquitoes, which then can infect people. The samples collected near the southwest side of the city of Springfield have tested positive for the West Nile Virus.

Most human West Nile virus infections are mild, but a small number of people become very sick. Less than one percent of infections develop into the life-threatening West Nile Encephalitis. Other clinical signs may include fever, weakness or paralysis of hind limbs, impaired vision, ataxia, aimless wandering, walking in circles, hyperexcitability or coma. These symptoms may last several weeks, and neurological effects may be permanent.

ยท No symptoms in most people. Anyone who develops symptoms should seek medical care immediately.

"This type of mosquito is most active at dusk and dawn".

Wear loose, light-colored, long clothing to cover the arms and legs when outdoors.

Doors - Make sure doors and windows are in good repair and fit tightly, and fix torn or damaged screens to keep mosquitoes out of the house. A mosquito needs only a few drops of water in order to breed and lay eggs.

Cleaning and emptying any water-holding containers on a weekly basis. Drill holes in tire swings so water drains out.
