Summer Brings West Nile Virus Concerns

WEST RICHLAND, Wash. - Summer again brings the threat of West Nile virus.

The virus has been in the U.S. since 1999, and can be deadly for a small percentage of those infected.

It's carried by mosquitoes, whose bites can transfer the virus to humans.  Washington is one of the few states that has not yet had a human contract the virus.

This year, Benton County Mosquito Control officials have yet to find an infected mosquito.  Last year the first appeared in late summer.

Health officials want you to keep vigilant to prevent the spread of mosquitoes by eliminating standing water on your property.
