The Franklin County Mosquito Control District announced Wednesday another batch of mosquitoes have tested positive for the virus.

David Dorsett, director, said the mosquitoes were found on North Wahluke road in the Northwestern part of Franklin County.   Areas where mosquitoes are known to be found or active are tested weekly, and they are closely monitored by districts in Franklin, Benton and other counties.

This is the second such discovery of infected insects this summer.   The district immediately plans aerial and ground treatments in affected areas, and those surrounding them, for the rest of the mosquito season.

West Nile Virus usually only affects about 1 in five people who are bitten by a carrying insect, most will not develop symptoms.  However, if a person does contract the virus there is no vaccine or treatment.   In some cases, especially in very young infants, elderly or those in very poor health, people can develop a serious and sometimes fatal neurological illness.  

The Franklin County Mosquito Control District recommends people cover their arms and legs if they are going to be outside for prolonged periods of time, especially in areas where mosquitoes are prevalent.   They also recommend use of repellants and other proven products to ward off the insects.  The virus and infections have been documented in virtually every state of the U.S.

Homeowners can also prevent mosquito activity and cut down on other insects around their home by removing or eliminating any sources of standing water,  excessive shrubs, weeds or other plant cover, and applying safe, approved insect treatments in suspected areas.
